9. Head, pronotum and limbs more decidedly marbled with the 

 paler and more reddish brown. Abdomen dark brown, faintly and very 

 widely punctate with a paler shade. Tegmina very dark brown with a 

 buffy marking filling the brief exposed portion of the dorsal field. 



MEASUREMENTS (IN MILLIMETERS) 



The series before us, in addition to the type and allotype, 

 may be considered paratypic. 



Specimens examined, 5 ; 3 males and 2 females.

McNeill's description and figures leave little room for doubt 

 as to the synonymy of his TV. specnli with the present species. 

 The two adult males described by him agree in all essential 

 details with those before us. That author gives 3 and 3 spines 

 for the margins of the caudal tibiae and 6 spurs, apparently 

 overlooking the absence of the ventro-internal spur, a charac- 

 teristic of the present genus. The specimens are given as 5 

 mm. in length. 



When compared with H. alleni and H. liura, the present 

 species is found to be a smaller insect, agreeing in the robust 

 form and nearly quadrate dorsum of the pronotum. It is much 

 paler in general coloration, but the males before us have the 

 lateral lobes of the pronotum broadly banded with blackish
