NOTES ON TENTHREDINOIDEA, WITH DESCRIPTIONS OF 



NEW SPECIES. 



BY S. A. ROHWER, BOULDER, COLO. 



Paper VII. — New Blennocampin/e. 

 Claremontia, n. gen. 



Malar space linear ; clypeus truncate ; antennae long and slender, 

 almost as long as the body, the third and fourth joints equal in length ; 

 venation very much like Blennocampa altemipes (fig. 72, pi. XXXVI, Proc. 

 U. S. Nat. Mus., XXIX), the third cubital cell is shorter on the radius 

 than the second ; the transverse radius and the third transverse cubitus 

 running in about the same direction ; hind wings without a discal cell ; 

 the lanceolate cell of the hind wings longly petiolate, the radial cell 

 rounded at the apex and without an appendiculation ; there is no sur- 

 rounding nervure in the hind wings ; the tarsal claws with an inner tooth ; 

 the hind basitarsus shorter than the remaining joints. 



This genus is nearest to Ble?inocampa in venation, but it differs from 

 that genus in the long antennae. The long antennae are suggestive of 

 Phymatoceros, but that genus has the third cubital cell longer and the 

 tarsal claws are cleft. Type, Claremontia typica, Roh. 



Claremontia typica, n. sp. — Female : Length, 6 mm. Anterior 

 margin of the clypeus truncate ; middle fovea and the ocellar basin want- 

 ing ; the ocellar furrows reduced to foveas, which are confined to the 

 ocellar region ; scape globose, the antennae clothed with short black pile ; 

 the entire insect shining and nowhere densely sculptured. Stigma rounded 

 on the lower margin, broadest in the middle ; the transverse radius 

 interstitial with the third transverse cubitus. The sheath is parallel-sided, 

 the apex obliquely truncate. Colour black ; legs below the femora 

 brownish, paler at the base of the tibiae. Wings dusky hyaline, strongly 

 iridescent ; venation black. 



Male : Length, 5 mm. The male agrees in general with the female, 

 but the legs below the femora are, as a rule, paler. The antennae are as 

 long as the body ; the hypopygidium is very obtusely rounded at the apex. 



Type locality : Mountains near Claremont, California. Four males 

 and two females collected by C. F. Baker. 



Peridista leucostoma, n. sp. — Female : Length, 5 mm. Anterior 

 margin of the clypeus semicircularly emarginate, the lobes broad and 

 rounded ; the ocelli in a low triangle ; the ocellar basin wanting, the 

 furrows around the ocelli distinct ; the front finely punctured ; the antennae 

 normal, the third joint distinctly longer than the fourth, which is equal in
