A New Ascalaphid from the United States. 



By NATHAN BANKS. 



Our Ascalaphid fauna is not very large at present. There are 

 three species of Ptyn.v from the extreme southern parts, one 

 Colboptcrus, and two species of Ulnla ; to this last genus I now 

 add a third. No species are at present known from Califor- 

 nia, so it is quite probable that a few more species will be added 

 to our meagre list. 



The new species comes from Arizona, and is closely related 

 \.o Ulula hyalina, but distinct by a number of minor characters. 



Ulula albifrons n. sp. 



Clypeus and mouth parts yellowish ; head clothed with white hair, with 

 which some gray is mixed. Antennae brown, each joint narrowly tipped 

 with pale ; club pale brown, paler on tip, in length the antennae reach 

 only to the tip of abdomen. Thorax brown, mostly with white hair be- 

 low, some brown hair above, especially each side of the metascutellum ; 

 on each anterior lobe of the thorax there is a pale yellowish spot, a median 

 pale spot on mesoscutellum, and another on the metascutellum. Legs 

 brownish, paler at knees. Abdomen brown, mottled with paler brown, 

 and with black ; last segment partly yellowish above. Wings hyaline, 

 pterostigma dark brown ; venation black, except the costal margin near 

 base, which is yellowish ; ten to twelve cross-veinlets between radial 

 sector and radius before the pterostigma. 



Length 20 mm.; expanse 50 mm. 



Three specimens from Phoenix, Arizona, (Kunze). The dif- 

 ference between this and the allied. U. hyalina may be gleaned 

 from the following table of our three species of Ulula : 



1. Pterostigma yellow, on hind wings several dark clouds near tip. 



U. zuadripunctata. 



Pterostigma dark brown, sometimes one dark cloud in hind wings near 

 tip . 2. 



2. Front with white hair, antennae annulate, reaching to tip of abdomen, 



venation black, 10 to 12 cross-veins between radius and radial 

 sector, smaller species . U. albifrons. 



Front with dark hair, antennae not annulate, reaching beyond end of 

 abdomen, venation partly light brown, 15 to 17 cross-veinlets 

 between radius and radial sector, larger species . U hyalina. 



Anthocharis genutia has been quite plentiful this spring in New Jersey. 

 Mr. Witmer Stone took it at Meford ; Messrs. Viererk and Rehn at River- 

 ton ; Mr. Erich Daecke at Clementon ; Dr. Skinner and Mr. Thomas at 

 Westville, and Mr. W. G. Freedley at Crosswicks.
