20 Cameron, Hymenoptera Orientalia. 



Myzine bengalensis, sp. nov. 



Long. 15 mm. $. 



Hab. Poona, Bengal ( Wroughton). 



Bingham (/.r.,p.65) has been unable to assign the males 

 of the Indian species to their respective females, and 

 describes 7 males and 7 females as distinct species. 

 Doubtless direct observation will be necessary to unite the 

 sexes correctly ; and, in default of this information, there 

 is no course open but to treat them as distinct species. 

 Of males, no species is described with red on the abdomen ; 

 but of females, there are three with the abdomen red 

 wholly or in part. Of these the present species comes 

 nearest to M. mandalensis Magretti, but that has segments 

 1-5 of the abdomen red and both wings hyaline at the 

 base, the anal segments fuscous, the posterior wings 

 *' hyaline, the extreme apex somewhat fuscescent," the 

 tegulse flavo-testaceous, and, in length, it is only 9-10 mm. 



Head shining, rather thickly covered with long, white 

 hair; the vertex v\^ith scattered punctures, except in the 

 centre behind the ocelli ; the ocellar region being also 

 without punctures ; the front more closely and strongly 

 punctured ; the clypeus strongly punctured except the 

 apex ; its middle carinate. Mandibles black, slightly 

 rufous in the middle ; the palpi dark testaceous. Scape 

 of antennae shining, sparsely covered with long, pale 

 fulvous hair, and with large, deep punctures ; the second 

 joint also shining and punctured ; the flagellum opaque, 

 thinly covered with a pale down, the under side brownish ; 

 the basal joints produced on the under side beneath. The 

 base of the pronotum transversely aciculate ; the apex 

 bearing all over lar^e, deep punctures, and sparsely covered 

 with long, pale fulvous hair. Mesonotum shining, having 

 some large, deep punctures ; and a deep, wide inner and a 

 much narrower outer furrow on its apical two-thirds. Scu- 

 tellum shining, its sides and apex bordered with large,
