Genus Anisopodus, White.

Char, emend. Body elongated and extremely flattened. Pro- 

 thorax even on its upper surface, its lateral spines placed near 

 the hind angles. Elytra oblong-oval, flattened, without centro- 

 hasal ridges ; their apices sinuate-truncate and mucronate, their 

 sides each furnished with a sharp lateral carina extending from 

 the humeral angle to the tip. Thighs abruptly clubbed; the. 

 hind legs elongated, in the males of some species excessively so. 

 Ovipositor of the female not apparent. 



The last genus ( Ozineus) seems to form the connecting link 

 between the groups allied to Alcidion and the present genus, 

 some of the species of Ozineus (e. g. 0. mysticus and 0. rotundi- 

 collis) having very much the general appearance of Anisopodi. 

 The absence of the centro-basal ridges of the elytra, and the 

 elongation of the hind legs, however, amply distinguish Aniso- 

 podus from the four preceding genera. 



1. Anisopodus phalangodes, ^richs. 



Leptoscelis phalangodes, Erichson, Consp. Ins. Col. Peruana, p. 145. 



A. " oblongus, planus, badius, dense cinereo pubescens, infra lateri- 

 bus nigro vittatis : elytris seriatim fusco punctatis, apice mucro- 

 natis : pedibus posticis fortiter elongatis, femoribus abrupte cla- 

 vatis. Long. 5^ hn." (Erichs. I. c.) Eastern Peru. 



This species is distinguished from its congeners, to some of 

 which {A. arachnoides, A. cognatus) it is very closely allied, by 

 the sides of the breast and the abdomen being marked each with 

 a streak of a sooty-brown hue (extending to the deflexed margin 

 of the elytra), which, from the silky nature of the pile that 

 clothes the under surface of the body, is fainter in some lights 

 than in others, and in small examples is scarcely perceptible. The 

 site of the centro-basal ridges of the elytra is marked by a small 

 rounded tubercle coloured black. The male is much larger than 

 the female, reaching 5^ lines in length, the female being seldom 

 longer than 4^ lines. The hind legs in the male are sometimes 

 10 lines long. Besides the black spot on the elytra over the 

 centro-basal tubercle, there is, in the males, a larger and irre- 



medio late cano fasciato, fascia fusco maculata, postice sinuata et 

 fusco marginata. Corpus subtus testaceum. Pedes rufescentes, tibiis 

 apice tarsisque nigro maculatis ; tibiis anticis medio intus tuberculo 

 conico instructis. Long. 3^ lin. Hob, Rio Janeiro. Coll. Bakewell, 

 Bates, &c.
