66 Mr. Cameron on the 



The c? has the antennae longer than the body ; the third 

 joint thin, more than twice the length of the second, and 

 longer than the fourth, which is thicker than the third. 



Length 2 — 3 mm. 



Hab. Clydesdale, Dumfries, Colvend, Carruber Glen, 

 Dairy, Ayrshire. 



A larger and stouter species than T. ciibitalis ; differing 

 from it in having the antennae quite black, stouter, and 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 is 

 only about one fourth longer than the third, and the 

 nervures are dark fuscous.

 Black ; trochanters, base and apex of femora, tibiae and 

 tarsi, red ; hinder tarsi inclining to fuscous ; wings hyaline, 

 with a decided fuscous tinge ; the nervures dark fuscous ; 

 spurious nervures and cubitus stout, testaceous. Antennae 

 one-half longer than the body ; the third joint a little 

 longer than the fourth and thinner than it. Prothorax 

 striolated in front, rather densely covered with fuscous hair. 

 Scutellum coarsely rugosely punctured ; the cup twice 

 longer than broad ; its base and apex depressed, narrowed 

 and rather sharply pointed at the base, the apex rounded, 

 pitted along the sides ; the apical foveae round, deep. 

 Scutellar fovese wide, deep, extending backwards nearly 

 to the middle of the cup, and not completely separated in 

 the middle. Metapleurae densely pubescent ; the meta- 

 pleural keels stout, straight. Abdomen shorter than the 

 thorax, the hair fringe, dense, griseous. Legs densely 

 pilose. Radial cellule twice longer than wide ; the first 

 abscissa of radius about one-fourth shorter than the second, 

 which is straight and nearly half the length of the third ;
