Color: Black, area along inner margin of parapsides sometimes 

 greenish or gray metallic black; flagellum of antenna grayish dull 

 dark brown to grajdsh reddish brown, usually paler at apex and on 

 the whole of the underside; scape black, sometimes in part brown and 

 in some instances with a greenish reflection; coxae black or blackish; 

 femora outwardly usually dark brown or blackish brown, the anterior 

 and intermediate pairs usually with a bluish or greenish tinge and 

 posterior pair usually very distinctly greenish or bluish; tibiae browTi, 

 anterior usually more or less testaceous except for a stripe above, 

 posterior usuall}^ with a greenish or violaceous tinge or reflection; 

 tarsi straw color to testaceous; wings hyaline, wing veins testaceous 

 to brown, sometimes reddish basall}^. 



Male. — Length about 2-2.25 mm. Essentially like the female; 

 scape slender, portion bearing sensorial punctures not greatly broad- 

 ened apically and occupying two-thirds or somewhat more than two- 

 thirds of scape, sensoria rather fine and dense. 



Species characterized by smoothness of head. 



r?/^;e.— U.S.N.M. no. 18300. 



Remarks. — Redescribed from eight females and three males, includ- 

 ing type, allotype, and para types; all from Texas (Jan., May, June, 

 Sept., Oct.). Nine of the specimens are in the United States National 

 Museum; one is in the American Museum of Natural Histor}^, and

PERILAMPUS OCELLATUS. new species 



Female. — Length about 3-3.25 mm. Head: Frons with a carina 

 extending from beliind anterior ocellus downward on each side of 

 scrobal cavity to beyond level of insertion of antennae, this carina 

 not very prominent, sometimes maslced by sculpturing of head and 

 occasionally altogether absent behind anterior ocellus; frons laterad 

 of carina and ocellocular area weakly to distinctly sculptured, shag- 

 reened or irregularly rugulose; emargination of fronto vertex broadly 

 or rather broadly arcuate, the distance between lateral ocellus and 

 nearest point in edge of emargination considerably shorter than 

 shortest distance from this point to anterior ocellus, emargination 

 nearly reacliing hne tangent to anterior margins of lateral ocelli; 

 postocellar line longer than median line of vertex; lateral oceUi dis- 

 tinctly depressed, the vertex medially more or less distinctly elevated 

 and this elevation continued diagonally in front of lateral occlh; 

 upper margin of anterior ocellus usually falling markedly below 

 anterior edge of vertex and the ocelli sometimes noticeably smafl for 

 size of insect; sides of scrobal cavity distinctly shagreened or rugulose, 

 not sloping verj' sharpl}''; face at side of hypcrclj-pcal area quite 

 strongly flaring, the hyperclypeal area relatively not depressed or but 

 slightly so; eyes with a vitreous surface; face at side of clypeus
