Insects. 1923 



Sp. 57. Andrena Lewinella. 

 Melitta Lewinella, Kirby. 



Male. — (Length 3f lines). Black ; the antennae nearly as long as 

 the thorax ; the face clothed with pale rufous pubescence. Thorax, 

 the pubescence on the disk rufous ; wings iridescent, sub-hyaline, 

 slightly clouded at their apical margins ; the legs fuscous ; the apex 

 of the posterior tibiae and all the tarsi testaceous. Abdomen ovate- 

 lanceolate, fuscous, and having a thin griseous pubescence ; the 

 second, third and fourth segments have laterally a narrow white mar- 

 ginal fringe. 



There is that general resemblance between this species and the A. 

 picicornis, that I think it may in all probability be its male. I have 

 never met with either sex, and have only seen those in the Kirbyan 

 cabinet : both species were captured by Mr. Kirby at Barham, in 

 Suffolk, but were rare. 



Sp. 58. Andrena combinata. 

 Melitta combinata, Kirby. Melitta nudiuscula, Kirby ? 



Female. — (Length 4 — 5 lines). Black ; the face clothed with thin 

 pale rufous pubescence, that on the cheeks and vertex is nearly white. 

 Thorax clothed on the disk with rufous pubescence ; a thick incurved 

 fringe on each side of the metathorax much paler in colour ; tegulae 

 piceous ; the wings iridescent, slightly clouded at their margins, the 

 nervures testaceous ; the posterior tarsi, and the apical joints of the 

 anterior and intermediate pairs, rufous ; the floccus white ; the scopa 

 fulvous. Abdomen sub-ovate, slightly depressed, finely punctured ; 

 the second, third and fourth segments have a narrow white marginal 

 fringe, the first and second generally interrupted ; beneath, the mar- 

 gins are ciliated with long white hairs. 



Male. — (Length 4 lines). Black ; the antennae as long as the tho- 

 rax ; the face clothed with long pale pubescence, which is also the 

 colour of that on the disk of the thorax ; wings iridescent, slightly 

 clouded at their apical margins ; the apical joints of the tarsi piceous. 

 Abdomen ovate-lanceolate, a little pale pubescence, on the basal seg- 

 ment, and the margins slightly ciliated with pale hairs. 



I cannot regard Mr. Kirby's Melitta nudiuscula as a good species, 

 or as being distinct from the present. I consider it to be a specimen 

 of the female, having the marginal bands obliterated. This insect is 

 not uncommon in the London district.
