494 ON THE GENUS HYMENOTES. 



membrane qui recouvre le corps s'eleve au dessus du thorax, d'environ 

 quatre lignes ; chaque face laterale presente de six a sept nervures trans- 

 versales saillantes, assez egalement espacees : cette membrane est d'un 

 brun feuille-morte, transparente dans son premier tiers, opaque ensuite, 

 son bord superieur est presque arrondi, sinueux dans quelques endroits ; 

 la partie qui deborde la tete, finit en pointeet forme une sorte de grande 

 crochet, la partie posterieure de la membrane de passant l'abdomen est 

 tronquee droit et carrement, a son extremite. Antennes et pattes de la 

 couleur du corps; cuisses posterieures fortes, elargies : carenes superieures 

 des deux dernieres jambes munies de fines epines. Je n'ai pas pu dis- 

 tinguer le sexe.

Another species from Africa has also recently been present- 

 ed to the British Museum by the Rev. D. F. Morgan, of which 

 the following are the characters. 



Species 4. — Hymenotes platycorys. Hym. fusca, granulosa, pronoto supra 

 in folium maximum integrum rotundatum elevato, angulo postico inciso, 

 femoribus foliaceis posticis margine supero, (nisi ad apicem) integro.

The colour, in one specimen, is entirely of a dark rusty 

 brown, with the tips of the thighs darker ; but in the other, 

 the elevated leaf of the pronotum is varied with paler colour, 

 as in my figure. The head is elevated into an irregular tooth- 

 ed ridge between the eyes, the centre being impressed, (fig. 

 67, 5 a, the head seen sideways). The pronotum is elevated 

 into a nearly semicircular leaf, produced into a deflexed point 

 before the head, and extending considerably beyond the ex- 

 tremity of the body behind ; it is very finely granulose, and 

 with slight irregular veins ; its edge at the posterior part is 

 finely serrated, and the posterior angle is notched : its lower 

 division is composed of two leaves, which slightly open for 

 the reception of the back, but in its upper portion these two 

 leaves are soldered together into one plate. The antennce 

 (fig. 67, 5 b) are short and 14-jointed, very slender, except 

 the two basal joints, which are thickened, and the two or three 

 terminal joints, which form a very slight club : they are con- 

 siderably shorter than in Hym. rhombea. The prosternum is 

 produced like a cravat over the hinder part of the mouth. — 

 The four anterior femora are dilated and scalloped on the 

 lower edge, the two posterior are much thicker, serrated on 

 the under side with several larger blunt teeth ; they are entire 

 on the upper side, except near the tip, where they are irregu- 

 larly spinose : the four anterior tibia are dilated at the base;
