REHN AND HEBARD 231 



Size larger. Head with the occij)ut elevated but little dorsad of the pronotal 

 disk; fastigium with angle in profile slightly more acute than in male, faintly 

 more projecting cephalad, when seen from the dorsum of similar form, but 

 distinctly broader; frontal costa not specially narrowed between the antennal 

 bases, but faintly compressed ventrad of the median ocellus, with very faintest 

 indication of a median carinula dorsed:" eyes much less i)rominent, very sharp 

 ovate in basal outline, the apex dorsad, the cephalic margin flattened arcuate, 

 the caudal margin strongly arcuate, the ventral margin subangulate, greatest 

 depth of eye one and one-third times that of the infra-ocular portion of the 

 genae: antennae approximately subequal to the dorsal length of the prono- 

 tum, distinctly shorter than in the male, distal section rather more broadly 

 spatulate than in the male when compared with the slender proximal portion. 



Pronotum as a whole proportionately deeper than in the male, the dorsum 

 more tectate in transverse section: cephalic margin of disk arcuato-truncate, 

 caudal margin of disk subtruncate with a shallow, broad, median emargination; 

 dorsal carina moderately elevated, much more distinct than in the male; in the 

 region of the lateral carinae are present low, short, disconnected carinulae, 

 which in general are sHghtly divergent caudad: lateral lobes with cephalic 

 margin distinctly oblique truncate to the ventro-cephalic angle. 



Cephahc femora about one and one-third times as long as the disk of the 

 pronotum. Median femora subequal in length to the median femora. Caudal 

 tibiae faintly longer than the femora. 



Measurements {in millimeters). — These figures are of maximum and mini- 

 mum specimens and of others noteworthy for special features.
