1938, apparently should be added 77vichomalus trujillot Blanchard. 
Blanchaed described trujiiloi as a parasite of the oriental fruit moth in 
Uruguay. 
H. L. Parker recently sent to the Bureau of Entomology and Plant 
Quarantine specimens that he stated were bred from this moth at 
Montevideo, Uruguay, by Mesa Carrion, and that had been identified 
as Trichomalus trujillot by Blanchard. Parker recognized the Uru- 
guayan parasite as probably Dibrachys cavus and requested that they 
be compared with material of that species in Washington. So far as 
T can see these specimens do not differ in any respect from Dibrachys 
cavus, and since they also agree perfectly with the description of 
Trichomalus trujilloi I have no hesitation in declaring the latter name 
a synonym. 
Genus HYPSICAMARA Foerster 
HYPSICAMARA LACHNI (Ashmead), new combination 
Pachycrepis lachni ASHMEAD, Trans. Amer. Ent. Soc., vol. 14, p. 193, 1887. 
The types of Pachycrepis lachni Ashmead, which are in the United 
States National Museum collection, do not have complete parapsidal 
grooves and therefore do not belong in the genus Pachycrepis. The 
parapsidal grooves are present only on the anterior one-half of the 
mesonotum. In this respect, as well as in all other generic characters, 
this species seems to agree with Hypsicamara Foerster as represented 
by H. ratzeburgi, the genotype, of which I have seen specimens in the 
Naturhistorisches Museum in Vienna, Austria, identified by Gustav 
Mayr. 
Hypsicamara is very similar to Pachyneuron Walker, differing only 
by having a slightly longer and slenderer arena vein, idle 
although distinctly thick ened, is nearly uniform in width throughout 
its whole length, and by havi ing the abdemen in both sexes sub- 
cylindrical and distinctly narrower than the thorax. The genus may 
have to be synonymized with Pachyneuron eventually. 
Ashmead’s types of Hypsicamara lachni were reared from a pine 
aphid (Lachnus australis Ashmead) at Jacksonville, Fla. 
I have recently identified as H. lachni the following material re- 
ceived from Clyde F. Smith, of Ohio State University, and reared 
by him in connection with an investigation of the parasites of various 
aphids: 3 specimens reared from aphids on Pinus virginiana collected 
in Hocking County, Ohio, June 26, 1938; 19 specimens from aphids 
on Salix, Columbus, Ohio, June 19 and July 7, 1938; 5 specimens from 
an unidentified host collected at Mink Creek, Idaho, July 18, 1937; and 
6 specimens taken at Beaver Creek, Utah, July 25, 1937. Still more 
recently 6 specimens of what appears to be the same species were 
received through O. Peck, reared July 1, 1932, from aphids on Abies 
balsamea, taken at Fredericton, New Brunswick, Canada, by R. E. 
Balch.
