 Hab. Moreton Bay. Sent by Mr. Diggles. 



Of this magnificent insect I know but two specimens — one in my 

 o^\^l collection, the other in the cabinet of Mr. Bakewell. 



Genns Trichotheca. 



Caput (fig. 5 c) exsertum, valde deflexum, fere pei-pendiculare ; ociiHs pro- 

 minulis, oblongo-ovatis, intus obsolete sinuatis ; antennis corporis longi- 

 tudini fere aequalibus*, gi-acilibus, filiformibus, ad apicem vix incrassatis, 

 articido tertio quarto breviori ; ^;ft^j/.')- viaxiUanbus articido ultimo ovato, 

 ad apicem attenuato. Thorax subcylindricus, lateribus nou marginatus ; 

 antepectoris sepiiento antero-laterali (fig. 5 b) subtrigonato, angulo pos- 

 tico trimcato. ScideJlum trigonatum, lateribus sinuatum, apice trim- 

 catum. Elytra thorace multo latiora, oblonga, parallela. Pedes modice 

 elongati, graciles ; femoribus anticis (fig. 5 (T) incrassatis, subtus dente 

 valido productis, intermediis subtus dente parvo armatis ; tarsk graci- 

 libus, articido primo duobus sequentibus longitudine «quali, secimdo 

 elongato-trigonato ; unijne elongato, arcuato ; nngidculo (fig. 5 e) basi 

 dente valido armato. Corpus elongatmn, subcylindricum, hirsutum. 



Type, Trichotheca hirta, Baly. 



This genns ought to stand close to Adoxus, Kirby ; its elongated 

 body, slender filiform antennas, and incrassated anterior pair of 

 femora will separate it from the latter.

 T. elongata, subcylindrica, pallide fidvo-fusco, pilis concoloribus suberectis 



* In tlie figure of this insect, as well as that of Epiphi/raa intestinortiin, the 

 artist has drawn the antenn* rather too long in proportion to the bod}'.
