24 PEOCEEDINGS OF THE NATIONAL MUSEUM vol. Os 



The name given above must take the place of the time-honored 

 queroi Fitch, unless we arbitrarily fix the latter upon one of the six 

 or more species to which the brief original description applies. Dr. 

 E. P. Felt informs me that No. 828 of Fitch, the type of Emyoa 

 queroi is lost, hence there is no possibility of really identifying 

 Fitch's species. Under the circumstances it seems best to drop 

 Empoa querci Fitch ^^ as unidentifiable, action that will also cure 

 the more or less undesirable situation of there being in the same 

 genus specific names so similar as querci and quercus (the latter 

 the genotype). 



Male. — For color characters see key to color varieties and descrip- 

 tions farther on. Venation of tegmen as in Figures 2-9. Hypo- 

 pygium : Outer claspers narrowed from base, apical third upcurved, 

 apices rounded, a little divaricate; each clasper with a strong, 

 outwardly and posteriorly directed pale bristle arising near outer 

 basal angle (fig. 54). Ninth segment rather longer (as viewed 

 from side) than in other species, the upi^er posterior angle rounded 

 prominent, the lower receding (fig. 55). Inner claspers nearly 

 semicircular in shape, the two tangent ventrally, each tapering 

 gradually to a sharp point, the terminal fourth curved outward, then 

 forward, then downward (fig. 56). Aedeagus with three pairs 

 of appendages at the tip of which the inner pair are long pointed, 

 bent at about a right angle at the middle so that they cross each 

 other, the intermediate pair short and pointed, and the outer pair, 

 long, slender, aciculate and divergent. Seen from the side all of 

 these appendages have an anterior inclination or curvature, and 

 the aedeagus is reinforced by a median and two lateral thin lamel- 

 lae, the former with a hooked process apparently for muscle attach- 

 ment (figs. 56-58). 



Female. — For color characters see key to color varieties and de- 

 scriptions farther on. Eighth sternite moderately pointed medi- 

 ally, slightly emarginate laterally (fig. 101). Side view of hypo- 

 pygium as in figure 110. 



Length, 3.5-4 mm.
