242 Mr. E. Saunders' Synopsis of British 



wing ; apical segment of the body pilose, not carinated 

 beneath ; front legs entirely black ; calcaria pale, much 

 shorter than in <? . Length 12 — 15 mill. 



Hah. — Littlehampton, Norwich, Lowestoft, Chobham, 

 Hastings, &c., generally common.

Extremely like the preceding, but generally smaller. 

 (? differs from that of e.xaltaius in having the femora 

 and tibiae of all the legs more or less ferruginous, the 

 apical segment of the abdomen beneath narrower, and 

 the externo-medial nervure almost describing a con- 

 tinuous curve as it crosses the base of the 1st subniar- 

 ginal and the 2nd discoidal cells. Length 6 mill. 



? differs from exaltatns in being smaller, with shorter 

 wings in proportion ; the legs often more or less red ; 

 and the neuration of the wings as in the S . Length 

 6—8 mill.

Very like the two preceding, but easily distinguishable 

 by the more obtuse emargination of the base of the pro- 

 thorax. The <? may be further distinguished by the 

 narrow apical ventral segment, which bears a slightly 

 raised, pilose, central carina, and by the shorter cal- 

 caria of the posterior tibife, which do not extend to 

 three-fom'ths the length of the basal joint of the tarsi. 

 Length 3 mill. 



The ? also differs in having the apical segment of 

 the body beneath, with a smooth carina, and the pos- 

 terior femora at the apex and the tibiae red. Length 

 4 — 5 lines. 



Hah. — Erith, Darenth, Harrow, Littlehampton.

Smaller than the preceding ; 3' readily recognised by 

 the emarginate apical ventral segment, which is wide 

 and rounded at the sides, and has its sides fimbriated ; 

 the Gtli segment is slightly emarginate at the apex, with 

 an impression on each side of the emargination. 



$ differs in the smaller size, and entirely black legs,
