 ginal cell and not quite reaching the venation; head fully as broad 

 as thorax; ocelli rather deeply pitted, the 

 .space between the hind pair equal to some 

 what more than half that between them and 

 eyes; clypeus distinctly incurved; space be 

 tween eyes at top a little greater than length 

 of second joint of flagellum, this latter joint 

 more than one-third longer than the second ;

swollen anteriorly at the sides; parapsidal P. Boguei, 9. 



grooves distinct, not reaching base of dor- 



sulum; upper and posterior surfaces of middle segment distinctly sep 

 arated, the median transverse fold short and high, but rather broadly 

 truncate above, upper surface of middle segment sulcate down the middle, 

 the irregular transverse rugae strongest medially and toward the sides, 

 infrastigmal tubercle rather large, lateral teeth distinct; mesopleural 

 tubercle distinct; longer spur of hind tibiae equal to less than one-third 

 the length of first hind tarsal joint; abdomen fusiform, impunctate, im

 Length 34 mm. 



(^.Colored like the , the blue reflection perhaps stronger and 

 present on thorax above ; wings colored as in 9 > but subject to varia 

 tion, the black in some specimens reaching the apex of median cell and 

 beyond, and in most specimens is present in a 

 lighter degree in the marginal, third submarginal 

 and discoidal cells, the hind wings sometimes 

 almost entirely dark, the yellow only showing 

 as a small spot on the fore margin ; clypeus an 

 gularly incurved; space between eyes at top dis 

 tinctly greater than the length of second and 

 FK;. 14. -Third subm. cell, third antennal joints ; middle segment much as 

 in female, with the lateral teeth larger; longer 



spur of hind tibi* equal to about two-fifths of length of first hind tarsal 

 joint; impression of second ventral segment indistinct, situated basally; 

 fourth ventral with two heavy bunches of inwardly curling hairs, the fifth 

 with an apical transverse brush of shorter, erect hairs, subgenital plate 

 elongate, sides parallel, apex subtruncate, without hair, basally the plate

Texas; Colorado; Oklahoma Territory (E. E. Bogue). One 

 9 and four <$ specimens. 



Although resembling several of the preceding species, yet 

 Boguei is easily distinguished by its last antennal joint being 

 orange at tip (a character apparently constant) ; it has, more-
