Page 400 - At night I experienced an attack (for it deserves no less a name) of the benchuca, a species ofReduvius, the great black bug of the pampas. It is most disgusting to feel soft wingless insects, about an inch long, crawling over one's body. Before sucking they are quite thin, but afterwards they become round and bloated with blood, and in this state are easily crushed.
Page 331 - Male, 7 to 9 mm. long; caudal bursa with short dorso-median lobe, which often appears as if it were divided into two lobes and with prominent lateral lobes united ventrally by an indistinct ventral lobe; common base of dorsal and dorso-lateral rays very short; dorsal ray divided to its base; its two branches being prominently divergent and their tips being bipartite; spicules long and slender.
Page 182 - The sigmoid flexure was uniformly thickened. In tracing the bowel upwards the thickening became less marked and more patchy. The coats of the caecum and appendix vermiformis were uniformly hypertrophied, the mucous membrane presenting small patches of ulceration and necrosis. The lower end of the ileum was thickened in patches, and the mucosa congested over corresponding areas.
Page 308 - The position of the adult worms within these tumours is very remarkable. The greater length of their coiled-up bodies is embedded in the connective stroma, but the posterior extremity of the male with its copulating organs, and the anterior extremity of the female with its vaginal opening, are free in one of the spaces for the purpose of copulation and parturition.
Page 400 - Chili and Peru) was very empty. When placed on a table, and though surrounded by people, if a finger was presented, the bold insect would immediately protrude its sucker, make a charge, and if allowed draw blood. No pain was caused by the wound. It was curious to watch its body during the act of sucking, as in less than ten minutes it changed from being as flat as a wafer to a globular form. This one feast, for which the benchuca was indebted to one of the officers, kept it fat during four whole...

One which I caught at Iquique (for they are found in Chili and Peru) was very empty.

It was curious to watch its body during the act of sucking, as in less than ten minutes it changed from being as flat as a wafer to a globular form. This one feast, for which the benchuca was indebted to one of the officers, kept it fat during four whole months; but, after the first fortnight, it was quite ready to have another...
Page 159 - Fasciolopsis rathouisi (Poir.). The mouth at the top, and under it the genital pore and ventral sucker, behind which again is the uterus. The vitelline sacs are at the sides, and posteriorly in the central field the ramified testes ; the ovary is in front of the right one. (After Claus.~) ova of Fasciola hepatica are met only here and there in the bile-ducts and gall-bladder.
Page 289 - Many flowers which open early in the morning are only visited by particular butterflies which leave their nocturnal haunts at the same hour ; other flowers do not open till sunset, and they are visited by hawk-moths, silk-moths, owlet-moths and other Noctuae, which commence their ramblings when dusk sets in.
