Nomada vallesina, sp. n. 



? . — Length 8| ram. 



Head, thoreix, and legs bright ferruginous, without yellow, 

 except tbat the postscutellum is a sort of dull orange (black 

 at extreme sides) ; a little black above bases of antennaj and 

 around ocelli, black lines along sides of supraclypcal area and 

 halfway down clypeus, and cheeks posteriorly black, leaving 

 a very broad red band behind eyes ; mesothorax very densely 

 ])unctate, with a rather obscure median black band, the 

 ])laccs of the four yellow stripes of Xanthidium being very 

 vaguely indicated by suffused stripes of a lighter sbade of 

 red ; scutelluni strongly bilobate, red, the posterior corners 

 a little } ellowish ; pleura red ; region above and in front of 

 middle and hind coxae black; mctathorax red with a median 

 black stripe, its sides with rather abundant pale fulvous bair; 

 hair of head and thorax above short and scanty, pale orange- 

 fulvous ; face bioad; eyes reddish grey; antenna long, 

 entirely red, third joint about as long as fourth ; legs red, 

 with the hind femora sufl'used with black behind; tegular 

 large, red, strongly punctured. Wings dusky, stigma orange, 

 nervures fuscous ; b. n. just on basad side of t.-m. ; second 

 s.m. broad, about twice as broad above as third. Abdomen 

 dullish, minutely and closely punctured, red with extremely 

 broad lemon-yellow bands on segments 2 to 5, that on 2 

 invaded by red at the basal middle, but not nearly interrupted; 

 apical plate broad; venter immaculate red; first dorsal red, 

 with the hind margin sufl'usedly blackened, and some black 

 marks at extreme base. The coloration of the abdonicn 

 recalls N. obliterata, but the venation is not as in that insect. 

 In my table of Kocky Mountain JSoinada it runs to male 

 color udcnsis, but it is not like the feniale of that species.
