104 THE CA.NADIA.N ENTOMOLOGIST. 



hair is quite the same. It is also very hke C. ^^ypsicolois, Ckll., but d.ffers 

 from that by the much broader abdomen, with the second and third 

 segments very much more strongly [)unctured, and the darker, redder 

 stisma. 'Ihe lateral faces of truncation of metathorax are shining, vvitli 

 ])ihferous punctures ; the triangle (below the cross-ridge) is very shiny, 

 scarcely at all sculptured, except for a median longitudinal keel failing 

 below. The tegulte are rufo-testaceous, darkened basal ly. Second sub- 

 marginal cell very broad; b. n. falling a rather long distance short of t. m. 

 {ahnost reaching t. m. in gypsico/e?is). In Morice's European table (Tr. 

 Ent. Soc, Lond., 1904), C. Tucsofiensis runs to C. naniis^ but it is larger, 

 and the abdominal bands are by no means as broad as the spaces between 

 them. The malar space is, however, rather short for this groujj, and if 

 we look for the species among those with a short malar space (for which, 

 however, it is a little too long) it runs to 15, and has long erect hairs on 

 disc of second segment, but only short ones on the following. It could 

 then run to 19 (the intermediate joints of posterior tarsi being longer than 

 broad), but the sixth ventral plate is quite simple, there being at most a 

 faint basal elevation of small size to indicate the rudiment of a carina. 

 (This plate is also simple in gypsicolens, but in geranii it has a distinct 

 though delicate carina). 



Greeleyella BeardsUyi, Ckll. — -Boulder, Colo., June 5, 1905. (W. P. 

 Cockerell.) One r^ . This genus and species was previously known only 

 from the female, obtained at Greeley, Colo., where, as I learn from 

 Professor Beardsley, it visits the flowers of Malvastrufn coccineiim. The 

 male from Boulder has darker nervures, a less obliquely truncate marginal 

 cell, and the first recurrent nervure enters the first submarginal cell not 

 far from the end, instead of meeting the transversocubital. These differ- 

 ences may possibly indicate a second species, but I do not think so. The 

 sexual characters are as follows : Head broad and subcpiadrate : clypeus 

 creamy white, with a black process directed downwards on each side of 

 the labrum ; face otherwise dark ; labrum ferruginous, with a prominent 

 transverse ridge or keel; mandibles nearly all ferruginous; tibiae and 

 tarsi, and about apical -third of femora, light ferruginous. 



Since writing the above, I have found in my wife's collection a female 

 taken at Boulder, June 17, 1905, at flowers of Malvastncm. It agrees in 

 venation with the female ty]n\ There is also a male taken June 17. in 

 which the first recurrent nervure joins the transverso-cubital, but oilier- 

 wise identical with the male of June 5.
