EUCOELA SCOTICA. 205 



antennae one-half longer than the body; the third about one- 

 fourth longer than the fourth, which is narrower and thicker than it, 

 and slightly curved. 



Length 2 2 mm. 



The colour of the flagellum varies from dull testaceous 

 to bluish-black, and the quantity of black on the femora 

 varies. In some specimens not otherwise distinguish- 

 able from the type, unless it be that the radial cellule 

 is somewhat longer, there is a trace of the cubitus. 



Common.

 PI. XII, fig. 3. 



Eucoela scotica, Cam., Mem. Lit. Phil. Soc. Manch. (4), ii, 65. 



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

 tibiae piceous-black ; wings clear hyaline, but slightly pilose, the ner- 

 vures fuscous. Antennae nearly double 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 joint longer than the seventh, double 

 longer than wide ; the other joints not much thicker than it, but shorter 

 compared to the width. Cup of scutellum rather small ; the fovea at 

 apex round, deep, apex of cup projecting ; scutellum coarsely punc- 

 tured ; depression at base large ; cubitus indistinct, not much traced 

 beyond the angle of 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 metapleurse sparse. 



The cf has the antenna longer than the body ; the third joint thin, 

 more than double the length ;of the second, and longer than the fourth, 

 which is thicker than the third. 



Length 2 3 mm. 



A larger and stouter species than E. ciliaris, differ- 

 ing from it in having the antennae quite black, stouter, 

 with a less clearly defined club, and with the third joint 

 not much longer than the fourth. The radial cellule 

 also is shorter and much broader, it being not very 

 much longer compared to the greatest width ; the 

 second abscissa only being about one-fourth longer 

 than the third ; and the nervures are dark fuscous.
