CATALOGUE OF ORTIIOPTEROUS INSECTS. 



length of the metathorax. Wiugs twice the length of the 

 tegniina, scarcely extending beyond the extremity of the 

 metathorax, with a large pale semitransparent patch, desti- 

 tute of veins, near the base of the costal area. Legs, espe- 

 cially the four posterior, short ; the anterior pair strongly 

 dilated and foliaceous ; the femora strongly emarginate on 

 the inner margin ; the four posterior lobed ; tarsi with 

 small compressed joints. Abdomen of the female with the 

 sixth segment strongly dilated on each side ; oviduct ex- 

 tending far beyond the extremity of the body. 



I am induced to follow M. Serville in separating the 

 curious insect upon which he has founded this genus from 

 the preceding group, although it is certainly very closely 

 allied to such species as Haplopus micropterus {angulatus, 

 Burm.) and n. S2)inipes, G . R. Gray {Ph. angulata, Pal. B.) ; 

 the dilatation of the legs, the lobed condition of the hind 

 ones, the curious mirror-like patch at the base of the costal 

 area of the wings, and the dilated sides of the sixth abdo- 

 minal segment seem to warrant this step, which will, I have 

 no doubt, be fully confirmed when the male shall be dis- 

 covered.

The accompanying figure was made by me from the type 

 specimen described by Byrmeister in the Royal Museum of 

 Berlin. The male is unknown. 



Plate XXXVI. Fig. 1. The female, of the natural size.

 Haplopus, B, Burmeister, o. c. p. 577. 

 Haplopus, A, De Haan, u. c. p. 127. 



Body elongate ; abdomen much longer than the head 

 and thorax. Head armed with two long compressed por- 

 rected horns in both sexes ; ocelli distinct. Tegmina elon- 

 gate-ovate. Wings of the male very large, of the female 

 more than half the length of the abdomen. Legs long ; 

 tibise armed on the outer edge, with a small spine before 

 and another beyond the middle. Abdomen of the female 

 truncate at the tip ; oviduct not extending to the extremity 

 of the dorsal segments ; anal styles minute. 



I have been compelled to establish a new genus for the 

 reception of the two African insects described below, as I 

 cannot perceive their close affinity with Haplopus, suggested 

 by Burmeister and De Haan.
