THE ENTOMOLOGIST. 247 



the apical marginal of ihe clypens pale yellow ; the face 

 below the antennse with short white pubescence. Thorax : 

 the wings hyaline, their nervines and the tegulae testaceous ; 

 the coxae and femora rufo-piceous ; the tibiiE and tarsi pale, 

 the intermediate and posterior tibiae with a fuscous stain out- 

 side. Abdomen oblong, shining, and finely punctured. 



I have only twice taken this species, in Hampshire : it is 

 easily recognized by its black colour and the eight white 

 maculae on the abdomen ; the head of the female is sub- 

 quadrate, resembling that of an Osmia. The male is de- 

 scribed from a specimen obligingly sent to me by Prof. 

 Schenck, of Nassau. 1 have examined the unique specimen 

 of the male taken at Kingsbridge by Dr. Leach, and 1 find it 

 does not agree with that sent to me by Prof. Schenck : it has 

 yellow mandibles, and the labrum is yellow ; the first seg- 

 ment of the abdomen is shorter than in the male of H. 

 maculatus.

 In his ' Monographia,' Mr. Kirby remarks that " M. flavi- 

 pes is not very unlike the Apis Tumulorum of Linneus :" he 

 corrects to some extent the brief description of the 'Fauna 

 Suecica,' but only to the extent of showing that the antennae 

 are not so long as the body, and that they are fulvous be- 

 neath, with the three apical joints fuscous; the body is 

 described as being " atrum glabriusculum," and the insect is 

 said to be nearly of the same size as M. flavipes. When I 

 examined the type specimens in the Linnean Museum some 

 years ago, I found them covered with dirt or dried mould, 

 and, relying on Kirby's examination of them, took no trouble 

 towards a better examination. I have again had an oppor- 

 tunity of examining them under favourable circumstances. 

 I cleaned the specimens thoroughly, and, having the advan- 

 tage of a bright day, have drawn up the following descrip- 

 tion : —
