the latter infuscated toward tip with extreme apex white, trochan- 

 ters white, tibia white with an obscure brownish annuhis near the 

 base and a broad nearly black one at apex, tarsi fuscous the first 

 joint whitish at extreme base. 



Type locality. — Santa Cruz Mountains, California. 



Type.— Cat. No. 19174, U.S.N.M. 



A single female bearing the Bureau of Entomology No. 23502, 

 which refers to a note in the Bureau files that records the specimen 

 as having been reared, but from what host is not known. 



The cocoon is about a third of an inch long by a third as wide, 

 loosely woven and net-like, and pale pinkish-brown in color. 



POLYSPHINCTA (ZATYPOTA) CROSBYI, new species. 



.Ulied to californiensis Cushman but easily distinguished by its 

 convex temples, longer second tergite, and genfM-aUy inore slender 

 form and darker color. 



Female. — Length 4.5 mm., antennae 3.5 mm., ovipositor 0.3 mm. 



In addition to tlie above charcxcters this species may be distin- 

 guished from californiensis by the following: First tergite with its 

 sides concave between the spiracles and the apex, the latter promi- 

 nent; second tergite about as long as wide at apex; transverse cubi- 

 tus distinct. 



Color pattern same as in californiensis but darker througliout, 

 metasternum as Svell as prosternum and mesosternum black, all coxae 

 and femora testaceous, those of front and middle legs somewhat paler, 

 tibiae with the usual annuli, testaceous on middle and fuscous on 

 hind tibiae ; pale bands of abdomen narrower. 



Male. — Length 4.0 mm., antennae 2.5 mm. Differs from female in 

 having venter of thorax and appendages paler throughout, though 

 dorsally not materially different, except that pale bands of abdomen 

 are even less distinct; propodeum with furrow stronger, almost cari- 

 nate; first and second tergites relatively somewhat shorter, the first 

 with sides straight and spiracles not prominent. 



Type locality. — Oswego, New York. 



Other locality. — McLean, New York.
