Melissodes glenwoodensis, sp. n. 



5 , — Length about 12 mm. 



Sbininj? black, witb greyish-wbite pubescence (not at all 

 fulvous or ocbraceous) on bead and tborax ; middle of tborax 

 nude, witbout black bair ; flagellum dark, obscurely reddened 

 bcncatb ; bair of apex and venter of abdomen black or sooty ; 

 tbe abundant scopa on outside of hind tibiae and tarsi 

 Avbitisb, with a strong redrlish tinge. This is a species of 

 tbe group of M. dc.yjonsa, and is very closely allied to 

 M. mysops, Ckll., from which it is distinguished by the 

 shorter abdomen, and particularly by the eyes distinctly 

 diverging above (in mysops they are practically parallel) ; 

 also by the larger and therefore less numerous punctures of 

 the clypeus, the redder tegulse, and the largely pale hair on 

 the four anterior legs. The hind femora are clothed with 

 black hair in mysops, but witb light hair in glenwoudensift. 

 From M. cnici, Rob., tbe new sjiecies differs at once by tbe 

 conspicuous white abdominal bands, narrow and widely 

 interrupted on the second segment, broader and very 

 narrowly interrupted on the third, and very broad and not 

 or very slightly interrupted on the fourth ; it also differs by 

 the more shining surface, the colour of the eyes, &c. 



Hah. Glenwood Springs, Colorado, Sept. 15, 1903, "only 

 a few specimens seen'' ; collected by Prof. C. P. Gillette. 



This is so close to M. mysops that I should be inclined to 

 ascribe the various little differences to variation, were it not 

 for the evidently different set of the eyes. The abdomen 

 appears more globose and convex, but this is no doubt largely 

 due to retraction. 



Melissodes Mizea, sp. n.
