HENRY J. FRANKLIN. 175 



in the least arcuate ; hair of head long and black, a little pale on lower 

 part of front, that on top of head behind ocelli entirely very pale ochre- 

 ous, but that on cheeks black ; hair of thorax long and loose, very pale 

 ochreous, a moderate amount of black on posterior middle of meso- 

 thorax and middle of scutellum, hair of hind part of pleura (especially 

 a tuft beneath wings) and of metathorax black ; tegul^ with a rufous 

 spot posteriorly. Wings dusky, strongly reddish. Legs with black 

 hair, that on inner side of tarsi dark red except at base ; hind tibiae 

 slender, convex ; hind basitarsi hardly as broad as tibiae. Abdomen 

 shining, with abundant black hair, but a large pale ochreous tuft at 

 each side of first segment, and small yellowish-white tufts on sides of 

 segments 3 to 5." 



" Distinguished from the North American species by the 

 colors of the pubescence ; also as follows : Compared with 

 P, tricolor, Franklin, it is rather less robust, and the hair of 

 the abdomen is considerably shorter; the wings are much 

 redder; malar space shorter (its length perhaps a trifle 

 greater than width of mandibles at base, but in tricolor much 

 greater); mandibles much more slender ; third antennal joint 

 shorter ; hair of hind tibiae and basitarsi very much shorter, 

 mostly not longer than half diameter of leg. (The male of 

 the European P. guadricolor, Lep., has even shorter hair on 

 hind basitarsus, but long hair on the tibia. The male of the 

 European P. campestris (Panz.) has the hair on hind tibia 

 and tarsus practically as in P. guatemalensis.)
