 the prozonal carintc compressed ; doraum forward between the 

 shoulders I'ather roundly elevated, cristate ; median carina strongly 

 sinuate, but continuous throughout ; dorsum profoundly fossulate- 

 reticulate ; lateral carinse sinuate and serrulate, bearing spiniforra 

 tubercles backward, and near the apex abruptly narrowed acuminate, 

 the apex curved upwards ; lateral lobes of pronotum widely laminate 

 expanded, sub ti^ansverse, erose, behind produced in spiniform tubercles. 

 Anterior and middle femora strongly trilobate-spinose, superior tibial 

 margins bituberculate ; posterior femora having the apices trispinose 

 and bearing a large triangular lobe, the antegenicular spine produced, 

 the superior margins bearing a denticle near the middle, siiperior 

 area of the external pagina multigibbose or nodulose, the external 

 carinpe armed with one tubercle above and two below distinctly 

 evident when viewed from above ; hind tibiae obscure fuscous with 

 pale annulations near the knee ; the third pulvilli of the first tarsal 

 articles flat below, the first and second very small and little acute.

 (Not in preceding table.) 



Related to Cladonotus, Saussure, but having the pronotum truncate 

 anteriorly, and destitute of ramose process, the dorsum gibbose for- 

 ward in the middle, but not gibbose on each side of summit as in 

 Cladonotella ; the lateral lobes having the posterior angles somewhat 

 scabrous, laminate and obtuse, truncate obliquely behind, the margins 

 of lobe minutely armed with setae. Body tomentose, not bearing 

 spiniform tubercles ; stature very small, face nearly vertical ; vertex 

 very wide, bearing a tubercle on each side next to the eyes, but not 

 acute, middle dentate-carinate produced. Pronotum shortened, 

 truncate anteriorly, the dorsum compresso-gibbose forward, pos- 

 teriorly flattened declivous, apex truncate-emarginate ; prozonal 

 carinse small and little compressed. Elytra and wings wanting. 

 Anterior and middle femora strongly compressed, margins distinctly 

 lobate, superior tibial carinas lobate, posterior femora having the 

 proximal half crassate, the distal half reduced, superior external area 

 and external surface below nodulose and scabrous, antegenicular 

 lobes very large, triangular but not acute, the genicular lobes less 

 prominent ; first articles of the posterior tarsi little longer than the
