868 Mr. P. Cameron's descriptions of new 



Readily known by the piceous head and thorax and 

 long antennae, which are longer than in the other species 

 with open radial cellule. 



Hab. Dumfries, in June. 



Psichacra glottiana, n. s. 



Black, shining ; apex of coxae, trochanters, base of 

 femora and their apical half, tibiae and tarsi, reddish. 

 Wings hyaline ; nervures testaceous. The antennae are 

 longer than the body ; the 3rd and 4th much thinner 

 than the other joints ; 5th thicker : the rest of nearly 

 equal thickness ; 3rd joint distinctly longer than 4th ; 

 5th shorter than latter ; 6th nearly of the same size as 

 5th ; the others to the 13th shorter, oblong, and covered 

 sparsely with microscopic bristle-like hairs ; the basal 

 joints of the flagellum are somewhat piceous. Scutellar 

 cup oval, rather shallow, a round fovea at its apex ; 

 foveae at base of scutellum moderately large and deep. 

 Below the cup the scutellum is smooth and shining ; 

 lower down coarsely punctured. The hair on metanotum 

 moderate in length, dull silvery white ; hair-fringe on 

 base of abdomen grey. Abdomen slightly aciculated on 

 basal half; apical smooth, shining. Radial cellule 

 closed, a little longer than broad ; margin deeply fringed ; 

 cubital nervure extending beyond the middle. The legs 

 are pilose. Length, nearly 3g- mm. 



Hab. Cambusland, on banks of Clyde. 



Psichacra similis, n. s. 



Black, shining ; antennae (except at base and apex) 

 and legs (except base of coxae) red. Wings clear hyaline ; 

 nervures testaceous. Antennae of the length of the 

 body, without a distinct club ; 3rd and 4th joints about 

 equal ; 5th a little shorter ; 6th scarcely tapering at 

 base and apex, the following distinctly so ; 9th to 12th 

 oval. Scutellar cup moderately deep, oval ; sides 

 coarsely punctured all round ; foveae at base of scutellum 

 moderate ; the outer margin striated. The hair on 

 metanotum is scattered and sparse. The male has the 

 antennae nearly three-quarter times longer than the body ; 

 the 3rd joint is, if anything, shorter than 4th. In colour 

 there is no difference between the two sexes, and the 

 wings are as in the other species. Length, 4 — 5 mm.
