WESTERN LEPIDOPTERA — I. 



BY KARL R. COOLIDGE, PALO ALTO, CALIFORNIA. 

 PlERIDAE. 



Euchloe pima Edw. — On March 10th, I received from Mr. N. Weil of Calhoun, 

 Kentucky, three euchloeid puj^ae, of Vv'hich he wrote, "Am sending you by to-day's 

 mail three anthocaris pupae; all I think are alive and healthy, notwithstanding the 

 fact that it has been almost exactly two years since pupation — to be exact pupation 

 took place March 10-20, 1906. All were taken on the same food-plant; don't 

 know the name, but think it is a species Turritis. Specimens were all taken at Tuc- 

 son, Arizona." Two of the pupae were of sara, or of one of its varieties, and the 

 other is undoubtedly pima as it comes from a locality in which that species occurs, 

 and it difl'ers distinctively from the pupa of sara, ausonides and lanccolata, all of which 

 are known to me. 



Pupa. — Length about 19 mm.; thin, sub-cyHndrical, of a light mouse brown, 

 streaked and speckled with darker; ventral surface but slightly darker than ground 

 color; posterior end to base of j)ronotum straight; pronotum rather high, abruptly 

 rounded; palpi-case straight, with not a trace of recurvation, as in other species; 

 spiracles indicated by blackish points. 



Dr. R. E. Ivunze, of Phoenix, Arizona, writes of pima, "I have never yet found 

 a pima ovipositing, and only know the plant on which the 

 imago feeds. Pivia is scattered over the desert, have often fol- 

 lowed it yet never took but one 9 while so doing. The latter 

 looks like the male, and one can hardly tell c? from ? after cap- 

 ture unless the abdomen is squeezed with a pair of forcei^s.

Last season i did not capture a single lemale. Mr. Vv. (j. lanceoiata. 

 Wright has the only 9 he ever saw from myself, which is figured 

 in his book. Yet that veteran collector had taken lepidoptera in Arizona for 

 more than twenty years." 



Euchloe lanceolata Boisd. — Mr. F. X. Williams has kindly made me the draw- 

 ing here figured of the pupa of lanceolata, which was described by myself in the 

 Canadian Entomologist, XL, p. 130. Several of the imagoes have emerged and 

 Mr. Williams tells me they are somewhat smaller than the adults of the var. australis 

 Grinnell (see Can. Ent. XL, p. 71). The measurement given for australis is 50 mm., 

 and for lanceolata 40 mm.
