suggest that they both may be good species. It was mainly the additional 

 material of rileyi from D. E. Davis, California, which helped to assess better the 

 range of variation. Yellow markings on the thorax are mostly narrower than in 

 texana, in one male they are reduced to narrow lines at hind margins of pronotum 

 and scutellum only.

Leucospis slossonae Weld 



(Text-figs 36, 37) 



Leucospis slossonae Weld, 1922 : 11-13, figs 5, 10, 14, 0. £. Holotype $, U.S.A.: Florida, 

 Capron (USNM). 



I examined two paratypes of this species kindly sent to me from the CU, Ithaca 

 and several specimens compared with the holotype by C. J. Weld and B. D. Burks. 



At first glance L. slossonae looks much darker than the two other species of the 

 group and usually is slightly larger, male 6-8-9-2 mm, female 7-4-9-5 mm. In 

 addition to the orange-red markings mentioned in the key, there is in the male 

 sometimes a small spot in the middle of the posterior part of the gaster, just above 

 the apical depression, the smooth bottom of which is surrounded by scattered 

 punctures so that the puncturation is not delimited abruptly. The markings in 

 smaller males often are more yellow and wings less infuscate. In the body colour 

 and geographical distribution the species shows an analogy with the dark-winged 

 and red-coloured subspecies floridana Cresson of Leucospis affinis Say, but L. 

 slossonae has also a different colour pattern of the gaster, which suggests that it
