Without any positive statement of the fact to rely upon, 

 I believe there can be no doubt that the Diura Typhosus of 

 G. R. Gray (which De Haan, Orth. Orient, p. 128, has, as 

 it appears to me, improperly regarded as the male of Cypho- 

 crania Goliath) is the legitimate partner of Tropidoderus 

 Childrenii. The amount of development of the wings seems 

 to be subject to some variation in this species, as Mr. 

 Fortnum brought from Adelaide specimens of the female 

 measuring 5^ inches in the length of the body, with the 

 wings expanding fully 9 inches, and with the tegmina 

 broader than in the type figured by Mr. G. R. Gray. I 

 cannot, however, discover any real specific character be- 

 tween these different specimens. It is true, that those from 

 Adelaide have the basal portion of the costal area of the 

 wings of a beautiful rose-colour ; the under surface also of 

 the whole of the costal area is of the same colour, with the 

 longitudinal veins pale yellow, and the tegmina also tinged 

 with rosy; whilst another specimen of the female, measuring 

 5 inches long, with the wings only expanding 6^ inches, has 

 the basal portion of the costal area half rosy and half pale 

 yellow.

The above is all the description of this supposed new 

 species which its author has thought it necessary to 

 give us. 



Genus 37. PRIS0PUS. 



Prisopus, Servi/le, Ene. Meth. t. x. 



Burmeister ; De Ilaan. 

 Prisopus et Platytelus, G. R. Gray. 



Body of the male somewhat linear, of the female broad 

 and subdepressed ; terminal segments of the body gene- 

 rally furnished with membranous lobes at the sides ; anal 

 styles moderately long. Head subquadrate and subde- 

 pressed ; ocelli wanting. Antennae long, pubescent, multi- 

 articulate. Prothorax and mesothorax of nearly equal 

 length. Tegmina elongate-ovate, generally about two- 

 thirds of the length of the wings. Wings very broad and 

 rounded, generally not quite covering the extremity of the 

 abdomen. Legs, especially the anterior and posterior pairs, 

 with dilated membranous sinuated lobes on the femora, the 

 margins of which are strongly ciliated ; tibife dilated, the 

 anterior pair with two small membranous detached lobes 

 at the base ; basal joint of the tarsi of moderate length. 

 Abdomen of the females with the ovipositor flattened, and 

 not extending beyond its extremity. 



The general habitat of these curious insects appears to be 

 South America, although Amboyna was given as that of 

 the typical species by its first describers. Whether the 

 "habitat in Indiis," given by Lichtenstein to Ph. Ohrt- 

 manni, be intended for India, appears to me very doubtful. 

 Two pupse are, however, figured by Stoll, one of which is 

 stated to be from Samarang, Java, and the other from 

 India. Some credibility seems to be given to these locali- 

 ties by that of the Cape of Good Hope given by De Haan 

 to Ph. Horstokkii (which may possibly be doubtful), and 

 also possibly by that of the Isle de France given as the 

 country where the unique specimen of Pr. Marchali (Xe- 

 roderusl Marchali, ante, p. 103) was taken by M. Marchal 

 himself, who resided in that island. 



Hitherto the characters of the genus have been derived 

 from females alone, no specimen of the opposite sex 

 having hitherto been described by any previous author : 

 Burmeister indeed considered the genus Xerosoma as the 

 males. The males of several species are described below. 



1. (437.) Prisopus flabelliformis. 

 Depressus, obscure virescenti-cinereus ; abdomine lato, 

 fulvo, segmentis 6 1 ", 7 mo et 8 T0 lobatis ; thorace brevi, depres- 

 siusculo, prothorace 2-spinoso ; elytris viridibus obscure ne- 

 bulosis, apice magis brunneis ; alis albo-cinereis, venis basi 

 viridibus, fusco undatis, costa pallida in medio maculis 

 magnis fuscis, apice brunnea ; pedum anticorum et posti- 

 corum femoribus late membranaceo-marginatis sinuatis ;
