British Species of Allotrince. 65 



and equal in breadth to it, moniliform. Scutellum rugose 

 at its sides and apex ; the basal foveae deep and wide. 

 Metapleurae densely covered with griseous hair. Abdomen 

 compressed laterally, lenticular, longer than the head and 

 thorax united ; piceous towards the base and apex ; the 

 hair fringe moderately broad, brownish, griseous at the apex. 

 The first abscissa of the radius curved, fully one-half the 

 length of the second, which is also curved and three-fourths 

 of the length of the third ; the latter straight ; the cubitus 

 reaches quite close to the apex of the wings. 



Length 4^ mm. 



May be known from T. scutellaris by the shorter an- 

 tennae, which are also thicker, with the club more distinctly 

 abrupt ; the third joint is not one-half longer than the fourth ; 

 the sixth not longer than the seventh ; the wings shorter 

 and clear hyaline ; the abdomen longer, being longer than 

 the head and thorax united. 



Hab. Cambuslang on the Clyde. 



EUCOILA SCOTICA, Sp. flOV. 

 Black ; the knees, four fore-tibise and tarsi, piceous-red ; 

 the hinder tibiae piceous-black ; wings clear hyaline, but 

 slightly pilose ; the nervures fuscous. Antennae nearly 

 twice the length of the thorax, with an 8-jointed club not 

 clearly separated ; the third joint not very much longer 

 than the fourth ; the sixth longer than the seventh, twice 

 longer than wide ; the other joints not much thicker than 

 it, but shorter compared to the width. Cup of scutellum 

 rather small ; the foveas at apex round, deep ; apex of cup 

 projecting ; scutellum coarsely punctured ; the depression 

 at base large. Cubitus indistinct, not much traced beyond 

 the angle of the radial cellule, which is short and broad ; 

 the first abscissa of radius slightly curved, one fourth 

 shorter than the second. Abdomen a little shorter than 

 the head and thorax united ; the hair fringe moderate. 

 Pubescence on the metapleurae sparce.
