FURTHER STUDIES ON NEOTROPICAL EPYRINI 
(HYMENOPTERA, BETH YLIDAE ) 1 
By Howard E. Evans 
Museum of Comparative Zoology 
This paper is a supplement to two recent papers published in the 
Bulletin of the Museum of Comparative Zoology. 2 Although these 
papers were several years in the making, as so often happens they had 
scarcely appeared when a considerable amount of new material came 
into my hands. The present paper is concerned with range extensions, 
notes on variation, and new species in the genera Rhabdepyris , Bakeri- 
ella, Calyozina, and Epyris. The abbreviations employed are the 
same as those used in my two previous papers, but for the sake of 
ready reference the abbreviations are listed again at the conclusion 
of this paper. 
Rhabdepyris (Rhabdepyris) muesebecki Evans, 1965 
This species was recorded from the United States only from two 
specimens intercepted at quarantine in Texas. However, it is ap- 
parently established in Texas, as I took a male while sweeping herba- 
ceous vegetation at the north edge of the city of Brownsville on 
June 29, 1965. I also have a female before me from Mera, Ecuador, 
collected January 26, 1923, by F. X. Williams [coll. Bishop Mus., 
Honolulu]. This is within the known geographic range of this 
species, but the specimen is of interest because of its large size ( LFW 
2.1 mm). It keys out well in my revision if one makes allowance 
for greater variation in size than previously indicated.
