20 (b). LEUCOSPIS AFFINIS, var. POEYI Guerin. 



Two specimens (male and female) of this variety from Cuba, de- 

 termined by Cresson, have been seen by the writer in the Academy 

 of Natural Sciences, Philadelphia. The yellow markings are more 

 conspicuous than in affinis. In the female the propodeum is not as 

 long as the metanotum, while in the male it is about twice as long. 



LEUCOSPIS BICINCTA Viereck. 



Leucospis bicincia Yikreck, Trans. Anier. Ent. Soc, vol. 32, 1906, p. 227. 



" Eeadily distinguished from all other American species by the 

 pale citron-yellow, almost whitish, markings and the two bands on 

 the abdomen, one being basal, the other in the middle. 



" 3Iah. — 5 mm. Structure, sculpture, and color pattern, with the ex- 

 ceptions mentioned as in affinis. Upper portions of front and occiput 

 and vertex strongly green, scape and next succeeding joint black, 

 the joint beyond this brown (remaining joints broken off), legs black, 

 with the following parts concolorous with the other pale markings ; 

 tips of the femora, anterior and posterior tibiae in front and middle 

 tibiae with the upper half in front, tarsi pale brown, claws dark 

 brown, wings faintly infuscated, the nervures black or nearly. 



" Type. — University of Kansas. 



" Type-locality. — Oak Creek Canon, 6,000 feet, Arizona. 



" One specimen collected in July by F. H. Snow, Arizona." 



The type of this species has not been seen by the writer, but from 

 an examination of three female specimens collected in Arizona, 

 which have almost white markings instead of yellow and which run 

 in the key to affimis., it seems quite probable that ticincta may be a 

 color variety of affinis. 



21. LEUCOSPIS AZTECA Cresson. 



Described from three specimens collected in Mexico by Professor 

 Sumichrast. 



Type. — Cat. No. 1799 and two paratypes in the Academy of Natu- 

 ral Sciences at Philadelphia. Seen by writer. There is one carina 

 on pronotum; propodeum about width of metanotum, with narrow 

 yellow band near its hind margin, punctate like rest of propodeum; 

 hind coxa is Avell covered with grayish hairs and has sharp spur on 

 upper margin ; seventh tergite yellow ; apex of abdomen except along 

 line of ovipositor yellow. 



22. LEUCOSPIS DUBIOSA Cresson. 



Described from one female collected by Professor Sumichrast in 

 Mexico. 



Type.— Csit. No. 1800 in the Academy of Natural Sciences, Phila- 

 delphia. Examined by writer.
