This species very closely resembles H. pteromalus. Mars., 

 but it is considerably larger, the external thoracic lateral 

 stria is longer, the inner subhumeral elytral stria is rather 

 fine but distinct, it does not quite reach the apex and ante- 

 riorly it does not quite reach the middle, the second dorsal 

 stria is complete, and the mesosternum anteriorly is very 

 distinctly emarginate. It also very closely resembles H. di- 

 visifrons, Sch., but it again differs as regards size ; it agrees 

 with the latter in having rather a longer external thoracic 

 stria behind the anterior angle, and in having an internal 

 subhumeral elytral stria. In H. dt'vistfrons the subhumeral 

 stria is longer and much deeper. The dorsal striae in 

 Schmidt's species are much stronger, and the third dorsal is 

 widely interrupted in the middle ; in H. bfahminius the third 

 dorsal is only basal, that is, there is no appendage. The 

 mesosternum is anteriorly sinuous in H. pteromalus, slightly 

 emarginate in H. divisifrons, and distinctly emarginate in 

 H. brahminius.

This species is, I have no doubt, the same as H. niponicus, 

 Lew., 1895. Reitter's name of nanus is a misprint for 

 navus, Mars.

L. 51 mill. 



Oval, rather convex, black and shining ; the head is feebly 

 divided into two lobes by a median impression, which widens 

 out triangularly behind the stria, stria strong and straight 

 anteriorly, surface inclosed by the stria is punctulate ; the 

 thorax, marginal stria fine and interrupted in front behind the 

 head, outer stria very short, little irregular, and confined to 

 the region behind the anterior angle, inner stria complete, 

 rather strong, and sinuous laterally, and at the base it turns 

 away from the posterior angle, the scutellar point is small and 

 on the basal edge ; the elytra, striae, outer humeral wanting, 

 oblique basal fine and nearly reaching the middle, a line of
