^ generally rather smaller than the S , and like 

 like the ? in colour and pubescence, but the head larger 

 and much wider than the thorax ; abdomen only 

 slightly larger than the head ; scape of the antennfe and 

 tibi?e with fine erect hairs ; extreme apex of the antennpe

 Differing only from the preceding in having the scape 



of the antennffi and tibiae without the erect hairs, and 

 being generally rather paler and smaller ; ? with the 

 costal area infuscate.

The (? of this species is easily distinguished from 

 either of the above by the much wider head, which 

 is wider than the thorax, by the mandibles being armed 

 with five teeth, and by the dark smoky base to the wings. 

 The flagellum of the antennae and the tibia? and tarsi are 

 also paler. Length 3—5 mill. 



The ? differs from the allied species in its brighter 

 brown, almost mahogany, colour, the large head, 

 which is wider than the thorax, the much smaller 

 abdomen, and the light clear brown antennae and legs. 

 Length 7 mill. 



The ? is of a pale yellow colour, and therefore 

 can only be confounded with L. fiavus, from which the 

 erect hairs of the tibiae and the denser hairiness of the 

 body generally distinguish it. Length 2 — 5 mill. 



Hal). — Generally distributed, and not uncommon. It 

 occurs in the London district, and I have taken it at 

 Chobham, Hayling Island, etc.
