Genera and Species of Hymenoptera. 537 



This does not appear to me to be L. Humbertianus, a 

 Ceylon species recorded by Bingham from Burma and Tenas- 

 serirn. The metanotal furrow is certainly not "supra bi- 

 spinosa," but the apical teeth are distinct enough and luteous 

 in colour. The scutellum in our species can hardly be said to 

 be divided in the middle by a furrow, except, perhaps, be- 

 tween the yellow marks, which have the appearance of being 

 slightly raised. 



Bingham (' Fauna of India,' Hym. i. p. 348), it may be as 

 well to point out, omits from his generic and specific descrip- 

 tions one of the most characteristic features of this genus, 

 namely, that the posfscutellum is armed witli a stout erect 

 spine. It is possible that the Burmese examples described 

 by Bingham as Humbertianus may be different from Saussure's 

 species, which was from Ceylon.

 from Britain and Two Species of Pompilus /iwn India. 



Haekeria, gen. nov. 



Radial nervure abbreviated, not reaching to the apex of the 

 stigma, the radial cellule therefore confluent with the cubital; 

 the cubital nervure almost entirely obliterated, only indicated 

 by a stump beyond the first transverse cubital, which is rather 

 faint, but not bullated. The first cubital cellule is confluent 

 with the first discoidal, through the obliteration of the cubitus 

 at the base; the transverse median discoidal nervure is not 

 interstitial with the marginal discoidal, being received shortly 

 beyond it; the second discoidal cellule is completely enclosed, 

 it and the costal and the median cellules are the only complete 

 cellules. Stigma linear, elongate, narrow ; the pterostigma is 

 distinct. In the hind wings there is only one nervure, which 

 is probably the subcostal, which ends in what may be a 

 stigma. Antenna} filiform, 19-jointed. Occiput margined. 

 Mandibles ending in a longish sharp tooth. Eyes prominent. 

 Parapsidal furrows distinct at the base. Scutellum large, 

 roundly convex. Median segment large; it has a gradual 

 rounded slope to the apex, which has a large distinctly defined 

 area, rounded at the top on either side, and between them in 

 the middle a narrower one, which is not very distinctly defined 

 on the top. Abdomen with a distinct petiole, which is about 

 four times longer than broad ; its apex is triangular and ends 

 in a short projecting ovipositor. 



This genus belongs to the Euphorides. It comes nearest 

 perhaps to Microtonus, with which it agrees in the paucity of
