New Species of Cladiinae Hymenoptera. 



By ALEX. D. MAC&LLIVRAY, Urbana, Illinois. 



The adults of all the following new species were bred from 

 larvae collected in New York by Dr. Hachiro Yuasa and in 

 Maine by Mr. Earl Shaw and the author for the Maine Agri- 

 cultural Experiment Station. The descriptions are published 

 so that the names can be used with descriptions of larvae that 

 are to be published. 



The types are deposited in the collection of the author. 



Trichiocampus pacatus n. sp. 



9 . Body black with the following parts white : trochanters, pro- 

 femora more or less at distal end, tibiae except distal one-fourth of 

 metatibiae, and tarsi except metatarsi ; clypeus broadly shallowly 

 emarginate ; median fovea elongate, shallow, continuous with ocellar 

 basin ; frontal crest not well developed, broken, represented by thicken- 

 ings on each side of break; ocellar basin distinct, depressed, lateral 

 walls fine, inconspicuous, linear, extending to lateral ocelli ; antennae 

 with third and fourth segments subequal, fourth segment longer than 

 fifth; head and thorax polished; wings infuscated, proximal two-thirds 

 smoky ; costa, stigma and veins blackish ; saw-guides with dorsal margin 

 straight, ventral margin convex, distal portion oblique, pointed above. 

 Length 5 mm. 



Habitat: Ithaca, New York. No. 88-1. 



The form of the frontal crest and the ocellar basin will dis- 

 tinguish this species. 



Trichiocampus patchiae n. sp. 



9. Body black with the following parts infuscated whitish: tro- 

 chanters, distal portion of profemora and mesofemora, tibiae, and 

 basitarsi ; clypeus narrowly, angularly emarginate ; median fovea cir- 

 cular, broad, shallow, inconspicuous ; frontal crest strong, unbroken, 

 narrow, rounded ; ocellar basin flat, limiting lateral walls rounded, not 

 linear, not conspicuous, a depression extending ventrad from median 

 ocellus; head and thorax polished; wings infuscated, proximal two- 

 thirds smoky, distal one-third clearer ; costa, stigma and veins brownish ; 

 saw-guides with dorsal margin straight, ventral margin convex, distal 

 portion blunt, pointed. Length 6 mm. 



Habitat: Orono, Maine. Sub. 100. 



This species differs from pacatns MacG. in the form of tlr 

 frontal crest. Named for Dr. Edith M. Patch, Entomologist 

 of the Maine Agricultural Experiment Station. 



Trichiocampus paetulus n. sp. 



9 . Body black with the following parts white : trochanters, cephalic
