cephalad and caudad of the transverse sulcus, which latter is well 

 impressed; collar with a fairly complete elliptical carinate figure, 

 which touches the transverse sulcus caudad; surface of the entire 

 pronotum acute tuberculate. Tegniiua slightly more than one and 

 one-third times the length of the pronotum, elongate-ovate, subhya- 

 line proximad in the sutural section, remainder opaque; costal margin 

 broadly arcuate, slightly flattened mesad, sutural margin moderately 

 arcuate, apex rotundato-rectangulate; costal veins numerous, stigma 

 small, linear, placed slightly proximad of the middle. Wings about 

 equal in length to the combined length of tlie head and pronotum, 

 opaque; costal margin straight in tlie proximal two-tliirds, strongly 

 arcuate in the distal third, the immediate apex rounded acute- 

 angulate, sinus distinct and mod- _ 



erately deep. Apex of abdomen 

 missing. Cephalic coxa? distinctly 

 compressed; dorsal margin with 5 

 to 6 teeth, between which are in- 

 tercalated one or more smaller den- 

 ticles ; ventral face thickly denticu- 

 late, the dcnticulations adpressed : 

 external margins finely denticulate ; 

 internal face of the coxje wdth a few 

 tubercles: cephalic femora slightly 

 shorter than the pronotum, the 

 greatest depth of the femora con- 

 tained four times in the length of 

 the same; dorsal femoral margin 

 straight, finely crenulato-denticu- 

 late; external margin with 5 spines, 

 of which the distal is very small 

 and placed on the genicular lobe; 

 internal margin with 14 spines, the 

 distal one on the genicular lobe and ^^^- 7.-€aijdomaxtis hosia. dorsal \tewof 

 the formula? reading proximad being 



iliililililili; discoidal spines 4 in number: cephalic tibise, exclu- 

 sive of apical claw, slightly less than half of the femoral length, 

 armed on the external margin with 7 spines placed on the metlian 

 and distal portions, internal margins with 11 spines increasing 

 in size distad: cephalic tarsi slightly longer than the tibiae, exclu- 

 sive of claw, the metatarsi slightly more than half of the entire 

 tarsal length. Median and caudal limbs moderately slender; median 

 femora nearly three-fourths the length of the pronotum; median 

 tibiiE slightly shorter than the femora; caudal femora but slightly 

 shorter than the pronotum ; caudal tibiae slightly exceeding the femora 

 in length.
