1752 Insects. 



Thorax clothed above with fulvous pubescence, much paler on the 

 sides, and white beneath ; the tegulae rufo-piceous ; the wings sub- 

 hyaline, clouded at their apical margins ; the legs dark rufo-pi- 

 ceous; the floccus white ; the scopa pale beneath, fuscous above; the 

 apical joints of the tarsi ferruginous. Abdomen oblong-ovate; the 

 margins of the segments piceous, clothed with a pale yellow pubes- 

 cence, the margins have each a white fascia ; the anal fimbria dark 

 fuscous ; beneath the abdomen rufo-piceous, and the margins of the 

 segments have a cilia of white hair ; on the fifth and sixth it is red- 

 dish-brown. 



This is a very rare species ; I do not know its locality : there 

 are several specimens in Mr. Desvignes's cabinet ; I am indebted to 

 that gentleman for my specimen. 



Sp. 45. Andrena Listerella. 

 Melitta Listerella, Kirby. 



Female. — (Length 5 — b\ lines). Black ; the face has a thin pale 

 yellow pubescence ; the antennae are fulvous beneath, excepting the 

 three basal joints. Thorax thinly clothed above with pale fulvous pu- 

 bescence ; the tegulae black ; the wings subhyaline, their apical mar- 

 gins slightly clouded ; the legs dark rufo-piceous ; the floccus pale 

 fulvous ; the scopa, and all the tarsi beneath bright rufo-fulvous. 

 Abdomen oblong-ovate ; the marginal fasciae very pale, nearly white 

 the anal fimbria slightly fulvous ; the margins of the segments be- 

 neath are thinly fringed with fulvous pubescence. 



Male. — (Length 4 lines). Black ; the face thinly clothed with pale 

 ochraceous pubescence ; the apex of the clypeus bidentate, there are 

 also two curved teeth on the labrum, and also a short acute tooth al 

 the base of the mandibles, which are long and curved. Thorax above 

 has a thin ochraceous pubescence ; the wings subhyaline, their apex 

 clouded; all the tarsi are bright fulvous beneath; the apical joints of 

 the tarsi rufo-testaceous. Abdomen ovate-lanceolate; the margins 

 of all the segments except the basal one, have a narrow fascia of very 

 pale ochraceous pubescence ; one or two of the apical segments have 

 their margins piceous ; beneath, the margins have a cilia of pale ful- 

 vous hair. 



This is a rare species, being I suspect extremely local ; I have 

 once or twice taken a specimen of the female, but only one of 

 the male ; I once saw several of both sexes captured in company, 

 and from the general resemblance between them, I have no hesitation 

 in uniting them ; the male is the denticulata of Kirby. I may here
