 DASYPODA SWAMMERDAMELLA. 



Order Hymenoptera. Fam. Andrenidae. 



Type of the Genus, Melitta Swamraerdamella, Kirbij. 



Dasypoda Lat., Fab., Sam., Curt. — Trachusa Jur. — Melitta Kirb. 

 — Andrena Rossi. — Apis Fab. 



Anienncs inserted near the middle of the face, rather remote, 

 filiform, as long as the thorax and 13-jointed in the male (1), 

 basal joint long and pilose, 2nd globose, 3rd obovate, scarcely 

 longer than the remainder, which are oblong and truncated ob- 

 liquely, terminal joint subovate : geniculated and 12-jointed in 

 the female (1*), basal joint the longest and stoutest, clothed with 

 long hairs, 2nd subglobose, 3rd long, slender at the base, the 

 remainder subquadrate, terminal joint subovate. 

 Labrum transverse, elliptic and convex ; the anterior margin 

 ciliated with long and stout bristles (2). 



Mandibles long narrow curved and crossing, deeply notched 

 below the apex, forming 2 teeth, pilose externally and internally 

 near the base (3). 



Maxillce long and broad, clothed at the base with long ciliated 

 hairs, terminal lobe as long as the Palpi, lanceolate, ciliated at 

 the apex (4). Palpi long, slender and tapering, 6-jointed, basal 

 joint shorter than the 2nd which is the longest, the remainder 

 decreasing in length (b). 



Men^MOT long and linear (5). Palpi as long as the maxillary, 



4-jointed, the joints clavate, basal the longest and stoutest, 4th 



the smallest (b). Labium inflexed, tapering, fleshy, as long as 



the Palpi (c). 



Males smaller and more slender than the females. Ocelli 3, nearly in 



a transverse line. Eyes lateral and narrow. Head not broader 



than the Thorax, which is subglobose. Abdomen ovate-conic in the 



males, ovate and depressed in the females and fringed at the apex. 



Wings with 1 marginal and 2 submarginal cells. Tibiae furnished 



with long spurs, very pilose, especially the hinder pair in the female, 



as well as the basal joint of the tarsi in that sex. Tarsi 5-joinfed, 



the basal joints very long especially in the 4 posterior of the males 



and dilated, particularly in the females. Claws bifid at the apex in 



the males. Pulvilli distinct. (8, /ore leg of female.) 



These handsome insects approach considerably in form some 

 of the Andrenae, but they are easily distinguished by having 

 only two submarginal cells. The sexes diifer so widely, that 

 they have been described under various names : the upper 

 figure in our plate is the male, and the lower one the female, 

 which I shall here describe.
