Melissina, gen. nov. (Anthophoridai.) 



Belongs to subfamily Eucerina, and is the Indian repre- 

 sentative of the American genus Melissodes, from which it 

 differs by the very short and deep marginal cell, the fourth 

 joint of raaxiliary palpus long, the less slender paraglossse, 

 the shorter tongue, and the much less tapering maxillary 

 blade. It differs at once from Cabitalia, Friese, which re- 

 sembles it in the five-jointed maxillary palpi, by the three 

 submarginal cells and long male antennae (these characters 

 as in Melissodes). The following description of the mouth- 

 parts is taken from a female of the tyje species ; the 

 measurements are all in microns: — 



Labial palpi 4-jointed, joints measuring (1) 750, (2) 355, 

 (3) 95, (4) 88 ; apical half of first joint hairy on one side ; 

 second joint very broad, very hairy on one side, pale, with 

 two broad brown bands, united by a longitudinal band; 

 last two joints stout ; paraglossse reaching nearly to end of 

 labial palpi; tongue com])aratively short, not extending 

 beyond paraglossse and labial palpi. ]\Taxillary palpi 4- 

 jointed (this also confirmed in male), the joints measuring : 

 (1) 160, (2) 160, (3) 145, (4) 95; first 'joint very stout, 

 second broadly colourless at apex and less conspicuously so 

 at base ; last joint slender, with two bristles at apex, 

 maxillary blade about 1280 long, very broad (about 480) 

 near base. 



Tibial scopa of female with plumose bristles, but these 

 have the apical 290 to 320 jx, simple. In the wings the 

 only marked feature is the very broad (deep) marginal cell, 

 vrhich is about as long as the discoidal, and ends rather 

 obtusely far from the costa ; b. n. not quite reaching t.-m. ; 

 second s.ni. quadrate, much shorter than first or third, 

 receiving first r. n. near its end ; third t.-c. strongly bent, 

 third s.m. on marginal about as broad as second. Labrum 

 einarginate at apex, and mandibles simple, in female. 



Melissina viator, sp. n. 



$ . — Length 9-10 mm., anterior wing about 7\. 

 Elack, for the most part densely covered with jiubescence, 

 except tiie hind margins of the abdominal segments, which 

 are bare and conspicuous ; hair of head and thorax white^
