 peculiar type found in the allied species, the median carina of the

 with five principal and six minor projections; prozonal crest moder-

considerable distance, the (X -2-) 

 greatest width of the prono- 

 tum, i.e., between these angles, is slightly greater than the length 

 from the cephalic margin along the median line to the caudal margin 

 exclusive of the projections; lateral lobes of the pronotum longer 

 than deep, ventral margin sinuate cephalad, ventro-caudal angle 

 rectangulate, caudal margin with three projecting tubercles, diverted 

 lateral carinse of the prozona strongly marked. Tegmina about 

 two and one-half times the greatest absolute length of the pronotum; 

 apical margin acute-angulate with the immediate apex rounded. 

 Wings about four-fifths the length of the tegmina. Prosternal ridge 

 lamellate, arcuate with the concavity cephalad, the greatest depth 

 mesad. Interspace between the mesosternal and metasternal 

 lobes very strongly transverse. Caudal femora slightly more than 

 four-fifths the length of the tegmina, the genicular lobes and the 

 medio-genicular process acute, medio-dorsal carina with three low 

 rounded lobes, ventro-lateral carina distinctly but not greatly 

 produced; caudal tibiae with eight spines on the lateral margins, 

 ten on the internal margins. 



General colors cinnamon, wood-broAvn, and seal-brown, 

 marbled and mingled together, lined, streaked and washed 

 one on the other. Head with the face darker than the vertex, 

 fastigium and genae, the carinse of the same region lined with 

 seal-brown; eyes raw umber; antennae Vandyke brown edged 

 with cinnamon. Pronotum with the disk and lateral lobes of the 

 prozona with seal-brown predominating, crest dirty wood -brown;
