REVISION OF LEUCOSPIDAE 65 



Hind femur not very densely punctured, interspaces mostly much broader than 

 punctures (latter at most as dense as indicated in Text-fig. 61) ; pale markings mostly 

 more extensive, on pronotum anterior cross-band always partly present; distribu- 

 tion more northerly ........... b 



Pale markings yellow to whitish; infuscation of wings moderate; from Canada to 



Mexico but not in Florida ...... affinis affinis Say (p. 65)

Leucospis affinis Say, 1824 : 326-327, $ £. Types, U.S.A.: Pennsylvania (lost). 



Leucospis subnotata Westwood, 1834 : 215, $. LECTOTYPE $ (here designated), Canada:

 Leucospis Canadensis Walker, i860 : 17-18, <J. LECTOTYPE <J (here designated), Canada 



(BMNH) [examined]. 

 Leucospis bicincta Viereck, 1906 : 227, $. Holotype <$, U.S.A.: Arizona, Oak Creek Canyon 



(SM, Lawrence). 



The type material of affinis and fraterna seems to be lost (cf. Peck, 1963 : 892). 

 One female standing (together with two more) under L. subnotata in the original 

 Westwood collection in Oxford and the only one fitting the description and bearing 

 the right data, was selected as lectotype, similarly as in the case of L. basalis, 

 where the male was labelled as paralectotype. I have, however, not found any 

 trace of the original material of L. druraei, which should have come to the British 

 Museum collections from the Entomological Society of London, but was not 

 recorded by Walker, 1846, while the specimen mentioned by him from Ohio is 

 still preserved, under affinis, along with one original male specimen of L. canadensis, 

 labelled as lectotype by Dr Burks during his visit to London in 1970. 



I could not examine the holotype of L. bicincta Viereck, but as my observation 

 of the range of variation confirms the assumption of Weld (1922 : 27) and of Gahan 

 (in Peck, 1951 : 593, where actually synonymized) , I regard bicincta a synonym 

 of L. affinis affinis Say, although the development of the white colour instead of 

 yellow may be connected with some climatic conditions. Apart from the two 

 Canadian specimens mentioned above and from the slightly different Lower 

 Californian specimens, the darker form with more or less reduced and white markings 

 comes mainly from the mountainous regions of south-western North America, 

 viz. from eastern California (Inyo County), Nevada (Washoe, Pershing and Lyon 

 Counties), Arizona (Yuma County, Phoenix, Globe, Huachuca Mts, Tucson, Pima 

 and Cochise Counties, Chiricahua Mts), New Mexico (Eddy County, Hidalgo County), 

 Texas (Big Bend National Park), and Mexico: Sonora (Magdalena, Ciudad 

 Obregon), Chihuahua (Chihuahua) and Coahuila (Saltilla). 



Apparently it was this subspecies (L. affinis affinis) which was studied by
