lum, though particularly distinct in having the margins of the male 

 pronotum crenulate. The margins of the male pronotum are entire, 

 with no trace of denticulation, in both vitrea and venosa.

This material, compared with specimens which we consider rep- 

 resentative of H. vitrea (StoU), shows that very close affinity exists. 



We separate the material here recorded by the more numerous 

 (twelve to fourteen) ^^ and closely placed spines of the cephalic 

 margin of the cephalic coxae, which increase somewhat irregularly 

 but strongly in length distad (particularly in females, length of 

 longest spine, cf .8, 9 1.3 mm.). The costal margin of the tegmina 

 is distinctly, moderately strongly serrulate. In the females the 

 pronotum has the margins of the collar and cephalic half of the 

 shaft strongly denticulate, the shaft with medio-longitudinal carina 

 subobsolete or weakly defined. In this sex the tegmina reach only 

 slightly beyond the apex of the abdomen, with marginal field pro- 

 portionately broader than in females of vitrea and with stigma more 

 ample (length 3.7 and 4.9 mm.).

The width of the marginal field of the tegmina in the male is 4.4, 

 in the females 5.6 and 5.8 mm. 



In the specimens at hand the cephalic trochanters are brown at 

 the apex, the femora above this point, above the first discoidal 

 spine and above the first and fifth larger spines of the ventro-internal 

 margin are flecked with brown. These markings are decided in 

 one female, very faint in the other two specimens. The larger 

 female has the stigma with small brown suffusions proximad and 



** Interspaced with additional very small nodiform spines.
