232 THE ENTOMOLOGIST. 



faint, parapsidal grooves distinct ; disc of scutellum sparsely punc- 

 tured ; enclosure of metathorax semilunar, distinctly margined, 

 coarsely and irregularly cancellate all over ; tegulte testaceous, darker 

 basally ; wings rather pale fuliginous, stigma black, nervures very 

 dark brown ; second submarginal cell slightly narrowed above ; abdo- 

 men broad but rather parallel-sided ; first segment with few scattered 

 punctures ; second with very minute close punctures basally, but the 

 middle portion with very sparse punctures ; third segment similar, 

 with the minutely punctured area larger ; fourth nearly uniformly 

 punctured, except the broad margin, which is impunctate on segments 

 one to four ; fifth with a dense apical fringe of white hair ; apical plate 

 rather narrow, truncate. 



Hah. Arroyo Pecos, Las Vegas, New Mexico, June 7th 

 {Wilmatte P. Cockerell). Differs from *S'. arvcnsis by the very 

 sparsely punctured disc of second abdominal segment ; from 

 S. sophice by its larger size and dusky wings ; from S. arvensi- 

 formis by the well-defined metathoracic enclosure, and narrower 

 thorax and abdomen ; from S. clematidis by the dark nervures, 

 less black at apex of abdomen, and rather larger size. 



Spliecodes sopliue, Ckll. 

 Colorado City, Colorado, at flowers of Primns, two females ; 

 Manitou, Colo., April 28th, at female flowers of Salix, two females 

 (7'. cC- W. Ckll.). New to Colorado. The specimens exhibit a 

 good deal of variation, but with the available material I cannot 

 distinguish more than one species. S. minor, Eob., is closely 

 allied to S. sophicE, but has darker wings, and appears to be less 

 punctured. It is possible that the two may prove geographical 

 races of a single species, when material has been collected all 

 across the country. In this case, minor will be the name for the 

 species, as it has at least six months' priority, both having been 

 published in 1898. 



Proteraner leptanthi, n. sp. 

 (? . Length about 9 mm. ; head, thorax, and legs black ; abdo- 

 men dark red, first segment black at base, and with a large black spot 

 on disc, apex broadly rounded. Mandibles and antennae entirely 

 black, fourth joint much longer than 2 + 3 ; mesothorax dull, very 

 strongly and closely punctured ; enclosure of metathorax without a 

 raised rim, but distinctly defined, with about fourteen very strong 

 longitudinal ridges ; teguhie shining piceous ; wings smoky at tips, 

 stigma and nervures piceous ; second submarginal cell narrowed at 

 least half to marginal ; abdomen rather broad, strongly punctured 

 all over. 



Hah. Manitou, Colorado, at flowers of Rihcs leptanthum, 

 April 28th, 1904 {T. cC- W. Ckll.). Allied to P. ranunculi, but 

 distinguished by the perfectly black antennae, strongly punctured 

 abdomen, &c. Six specimens were taken. On May 11th my 

 wife took one in Cheyenne Caiion.
