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 breadtli 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 eoronatum. (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 tibiae and the ovipositor marked with ferrugino-testa- 

 ceous; tips of the claws blackish. The lateral carinae of the head 

 below the eyes rendered conspicuous by about half a dozen slightly 

 appressed, 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 an 

 exceedingly slight impressed line. Ovipositor longer than the body, 

 equal, 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) antennas, 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 (fiiAos, xeyaXvj) nov. gen. 



Allied to Conocephalus. Body stout. Head of the general form 

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

 cylindrical thorn, tapering apically, bearing an inferior basal tooth, 

 but no lateral teeth ; eyes small, not very prominent. Prosternum 

 bispinous ; fore coxae 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, slightly 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
