and depressed on either side of a median ridge extending 
from the transverse frontal ridge to the clypeus, the two 
ridges forming a rough T. This flat, depressed, frontal area 
bears three transverse rows of punctures. Legs black to 
tips of femora, except the front legs which have a long 
yellow femoral stripe beneath, extending over half of the 
length of the femora. Middle and hind tibise entirely 
yellow, fore tibiae marked with black. Tarsi rufous, darker 
toward the apices. Wings dusky violaceous, darker on the 
anterior edge of the front wing.

Sapyga interrupta most closely agrees with the charac- 
terization of Sapyga americana Cresson, as given by him 
in his key to the North American Species of Sapyga (Trans. 
Amer. Ent. Soc., viii, p. xx) . It differs from that species, 
however, in having the clypeus immaculate. The writer 
has not had the opportunity of examining specimens of 
Sapyga americana, which species Cresson described from 
a specimen from New York State, but Sapyga interrupta 
differs from all specimens that he has identified, except the 
following, in having medially interrupted (not complete) 
yellow bands on dorsal abdominal segments 2 to 5. The 
first dorsal abdominal segment is unmarked, while segment 
6 bears a complete, transverse, broad yellow band. The 
ventral surface of the abdomen also bears yellow markings 
on each segment except the first.

of the clypeus, a line extending from the middle of the inner 
orbits of the eyes upward and practically filling the emar- 
ginations, a small dorsal spot on each side of abdominal 
segment 2, with dorsal bands on segments 3 to 6, narrowly 
interrupted on 3 and 4, more widely interrupted on 5, yel- 
low. The clypeus joined to the front a little below the 
frontal ridge, there being but a single transverse row of
