pubescence, the clypeus thinly so. Thorax fulvo-pubescent, thinly so 

 on the disk ; the tegulae rufo-piceous ; the wings hyaline ; the ner- 

 vures testaceous ; the floccus, scopa, and all the pubescence on the 

 legs is fulvous ; the claws ferruginous. Abdomen ovate ; the anal 

 fimbria bright fulvous ; beneath, the segments are fringed with hair 

 of the same colour. 



Male. — (Length 44 — 5 lines). Black; the pubescence is of a 

 brownish-yellow; the clypeus pale yellow, with two minute black 

 spots, clothed with a white pubescence, as well as the mandibles and 

 cheeks. Thorax, the tegulae and wings as in the female ; the coxa? 

 and femora beneath have a white pubescence. Abdomen, the five 

 apical segments have a thin brownish-yellow pubescence, and the 

 apical segment beneath fulvous. 



This species is very local near London, Hampstead Heath being 

 the only locality I know of; in Hampshire it is not uncommon, I have 

 there met with it in utter profusion ; it appears about the beginning 

 of June. The males soon change colour, the pubescence becoming 

 entirely gray.

 the pubescence on the legs, the floccus and scopa fulvous ; the apical 

 joints of the tarsi ferruginous. Abdomen shining, oblong-ovate, rather 

 depressed, punctate, the margins of the segments, except that of the 

 basal, piceous ; the second and third segments have a narrow lateral 

 fringe, the fourth a continuous one of fulvous hair, the anal fimbria 

 bright fulvous ; beneath, the segments laterally are fringed with ful- 

 vous hair. 



Male. — (Length 5 lines). Black, resembling the female; its pubes- 

 cence more inclining to ochre ; the pubescence on the clypeus white, 

 as it is also on the cheeks; on the coxae and femora beneath it is very
