5GS Descriptions and Records of Dees. 



&c. ; from Mesoplia regalis (Melissa reijalh, Sm.) by the 

 lack of ii;i'een on head and thorax, the red scape, &c. ; from 

 Mesoplia decorata {Melissa decorata, Sm.) bv the blue (not 

 green) abdomen, minuteness of the spines on thicker branch 

 of middle spur, pure white hair at sides of face, &c. The 

 venation agrees with that of M. decorata. I restore the 

 generic name Mesoplia, Lep. (type azurea), which seems to 

 have been set aside by Smith without any adequate reason. 

 Tlie species are rather " critical," owing to tiie fact that 

 they are not only closely allied, but it is difficult to secure 

 sufficient material for examination. 



Centris inermis yualanensis, subsp. n. 



$ . — Length about 17 or 18 mm. 



Only the hind legs with very much red ; anterior tibiae in 

 front black witli a yellow streak ; a small triangular supra- 

 clypeal mark ; vertex M'ith a broad band of brown-black 

 hair ; labrum yellow with a dark apical spot ; hair of thorax 

 above very bright orange-fulvous, not tipped with fuscous ; 

 wings very dark ; a large blue-green patch on fourth 

 abdominal segment. 



(J. — Face-markings bright lemon-yellow; supraclypeal 

 mark large ; scape yellow in front (with only a small pale 

 stripe in female) ; labrum entirely yellow ; all the femora 

 largely black ; second abdominal segment with a broadly 

 interrupted bright vcllow band, widening laterallv. 



Hub. Gualan, Guatemala, Feb. 22-23. 1912 [W. P. 

 Cockerell, 40). The type is a female of this lot. A female 

 was also taken at Quirigua, Feb. 20, 1912, on a bank 

 [W. P. Cockerell). Superficially this looks like C. bimaculata 

 or C. proximn.
