SCIENTIFIC EXPEDITION TO NORTHWESTERN COLORADO 12 7 



P. napi cruciferarum (Boisduval). Newcastle, August 2 (R.). Meeker, August 

 9 (R.); Buford, August 21 (D.). 



Eurymus eurytheme eriphyle (Edw.). Rifle Gap, August 4 (R.); Buford, 

 August 23 (D.). 



Hesperia tessellata Scudder. Newcastle, August 8 (R.). 



LEPIDOPTERA HETEROCERA 



Smerinthus jamaicensis geminatus (Say). Meeker, August 9 (R.). This is 

 apparently the most western record for this species, which is characteristic of the 

 Atlantic and middle states. Good specimens have been taken at Boulder by Mr. 

 G. Hite. 



Apantesis parthenice intermedia (Stretch). Rio Blanco, August 5 (R.). Hamp- 

 son's table, at the point where separation is made on the color of the abdomen beneath, 

 is unsatisfactory. The present specimen has the abdomen with a pair of large 

 quadrate black patches on each segment. 



Holomelina immaculata (Reakirt). Newcastle, August 2 (R.). 



Schinia acutilinea separata (Grote). Meeker, August 9 (R.). This is a true 

 separata, but the subterminal line is strongly sinuous, in the manner of acutilinea. 

 Dr. J. B. Smith's opinion that the two are forms of one species appears to be correct. 

 The common Schinia at Boulder is S. cumatilis Grote. 



HEMIPTERA HETEROPTERA 



Phymata erosa fasciata (Gray). On Solidago, Newcastle, August 8 (R.). 



Lygaeus reclivatus Say. Newcastle, August 1 (R.). 



Lygus pratensis (L.). On Solidago, ten miles east of Meeker, August 19 (R.). 



Alydus scutellatus Van Duzee. Buford, August 23 (D.). I had taken this for 

 a variety of A. conspersus Montandon (which is common on the university campus 

 at Boulder), but it certainly differs by the unspotted but marbled membrane, the 

 nervures anastomosing, and by the more slender hind femora with a pallid subapical 

 annulus. The scutellum is deep velvet-black, with the extreme apex white. The 

 membrane, however, is pale between the veins, and a considerable part of the under- 

 side of the abdomen is pallid, spotted with black and speckled with red. The type 

 locality of scutellatus is Beulah, New Mexico. The Buford insect is certainly scutel- 

 latus rather than conspersus, but perhaps a distinct variety. 



HEMIPTERA HOMOPTERA 



Ceresa basalis Walker. Buford, August 23 (D.). The common Ceresa at 

 Boulder is C. bubalus (Fabr.). 



HYMENOPTERA APOIDEA (BEES) 



Apis mellifera ligustica (Spinola). Meeker, August 8 (D.); Rifle Gap, August 4 

 at "bee plant" (R.).
