Stratiomyidae — JAMES

domen distinctly narrower than head; pile 
more prominent, particularly anteriorly; ven- 
ter with an extensive yellow median area on 
segments one to three. Genitalia yellow. 
Holotype: Female, Guam, on Ochrosia 
fruit, July 25, 1938 (R. G. Oakley); Guam 
no. 1205; Lot no. 38-14972; U. S. National 
Museum type no. 59338. Allotype: Male, 
same data. Paratypes: One male, live fe- 
males, same data; one female, Guam, Decem- 
ber, 1945 (R. M. Bohart); one male, one 
female, Point Oca, Guam, June 6 and 14, 
1945 (G. E. Bohart, J. L. Gressitt), at light; 
one female, Mt. Santa Rosa, Guam, May 16, 
1945; one female, native forest near Sabana, 
Rota Island, 1,200 ft., June 19, 1946 (H. K. 
Townes) . 
The infuscated wings, the darkened legs, 
and, in particular, the infuscated hind tarsi, 
and the V-shaped glabrous area on the front 
of the female will readily distinguish this 
species from all others known to me. The 
female of Cephalochrysa hovas (Bigot), the 
genotype, has the front more coarsely punc- 
tured except on a raised area next to the 
median suture; this area is broad and prom- 
inent, however, and does not expand below 
as in infuscata. C. hovas has been recorded 
from Hawaii, but the determination may be 
erroneous. No raised glabrous area occurs on 
the front of the other Oriental species, C. 
chrysidiformis (Lind.), C. maxima (de Meij.) 
and its variety demeijerei (Lind.), or C. steno- 
gaster James, or in any of the known Ameri- 
can species.
