 Named after 'Sir. Vornon Bailcv, in recognition of his 

 work on the zoolo^v of Texas. 



Melissode.s xanthopteralis, sp. w. 



(^ . — Length about 12 mm. 



Clypcus, habrum, and basal j)art of mandibles yellow ; 

 flagellum red beneath ; ])ubesceiiee dull whitisli, except that 

 of mesothorax and seutcllum, which is dull light oclireons. 

 Wings very yellow, the apex little infuseated ; tegulae red; 

 hind margins of alidominal segments dull white, thesubapical 

 region broadly reddened ; abdominal bands white (on middle 

 of segments 2 to 4) ; segments 5 to 7 with brown-black hair; 

 7 with lateral spines. 



Kuns both in my table and Robertson's to M. com])toidi'S , 

 Rob., but it does not look like M. compta, and the abdominal 

 fasciae do not seem to agree. The account of comptoides 

 would seem to apply even better (except in respect to the 

 ferruginous tarsi) to male gaJvestonensis, but the female of 

 that species does not agree with comptoides. M. xuntho- 

 pteralis differs from qalvestonensis by the broadly whitish 

 hind margins of abdominal segments, third segment with a 

 narrow white hair-band (an extremely broad one in galveston- 

 ensis), long liair at sides of segments 3 and 4 white (without 

 the conspicuous black bristles seen in galvesiotiensis and also 

 in communis) , wings yellower and not so dusky, tarsi ferru- 

 ginous, hair on outside of hind tibiie and tarsi white (fulvous 

 in galveslonensis), third joint of maxillary palpi shorter. 

 From M. kallstroemm jtlienacoides (which it resembles in the 

 colour of the wings and the colour and form of the abdo- 

 minal bands) it differs in the conspicuously broader abdomen, 

 the somewhat broader face, the broadly whitish hind margins 

 of abdominal segments, and the absence of black bristles on 

 basal part of segment 4. The abdomen is also much broader 

 than that of M. tepaneca and the bands are quite differently 

 coloured. P^'om the colour of the wings, ferruginous ner- 

 vures, and large oblique second submarginal cell, it cannot 

 well be the male of M. Bruesi, Ckll.
