This most remarkable genus belongs to the Conocephalidae, but is 

 not closely allied to any of the known genera ; its laterally tubercu- 

 lated and apically bidentate vertical spine allies it to Vestria Stal, 

 but the extreme breadth and shortness of this spine, and the extraor- 

 dinary flatness of the front of the head, distinguishes it at a glance 

 from every other genus. 



12. Lirometopum coronatum. (Figs 1-2.) Uniform tes- 

 taceous (but doubtless green in life), the prominences of the head, 

 front of mandibles, labrum and the parts above it, as far as a line 

 uniting the bases of the mandibles, piceous; the apices of the princi- 

 pal cross veins on the posterior border of the tegmina, the spines of 

 femora and tibi^ and the ovipositor marked with ferrugino-testa- 

 ceous; tips of the claws blackish. The lat(>rai carinse of the head 

 belov/ the eyes rendered conspicuous by about half a dozen slightly 

 a])pressed, short, blunt, conical tubercles of about the size of the api- 

 cal portion of the vertex ; front with a few broad, slight, vescicular 

 elevations in the central portions and some scattered rugosities be- 

 tween them and the coronate edges of the face. Pronotum with au 

 exceedingly slight impressed line. Ovipositor long-er than the body, 

 e([ual, excepting close to the tip, where it tapers by the excision of 

 the lower side, terminating in a blunt point. 



Length of body, 38 mm.; of (broken) antenna?, 60 mm.; of tegmina, 

 35 mm.' of hind femora, 19 mm.; of ovipositor, 26 mm.; height of face, 

 16.5 mm.; breadth of face, 12.75 mm, 1 ?, Greytown, New. Gra-

Belocephalus (^'fAf^c, xs<fa.hj} nov. gen. 



Allied to Conocephalus. Body stout. Head of the g-eneral form 

 of that of Conocephalus, the vertex greatly produced as a stout sub- 

 cylindrical thorn, taperin.g apically, bearing an inferior basal tooth, 

 but no lateral teeth ; eyes small, not very piT)mineut. Prosternum 

 bispinous; fore coxaa armed with a slender pointed thorn; pronotum 

 equal, arched, the front and hind border equally rounded, the latter 

 not produced and with a scarcely perceptible humeral excision, the 

 lower anterior angle of the lateral lobes distinct, the lower edge 

 nearly horizontal, shghtly and roundly excised in the middle; fore 

 and middle femora of about equal length ; hind femora slender, 

 tapering very gradually throughout, the lower terminal lobes with a
