ack legs and yellowish base of the wings. There is a female in 
e Entomological Club collection. 
tars^-s M- This, and the following, are considered the same by 
.ntine'ntar authors, but I agree with Zetterstedt in thinking that 
•iitarsis is well distinguished by its more bluish colour, more pel- 
.cid wings, smaller size, less pubescence, &c. ; the species are re- 
markable for their black legs, with the middle jomts of the front 
trsi yellow, and are distinguished by the almost bare arista from 
.utahUis. There are about four pairs of albitarsis in the Ento- 
lological Club collection. 
nmana, Mg., is much commoner than the last, occurring in tolera- 
te abundance about June, mostly in marshy places. 
'talilis Eln There is one male in the Entomological Club col- 
ection' this I refer with considerable doubt to this species, which 
s distinguished by its black legs, with the middle joints of the 
•ront tarsi yellowish, and by its rather small size and pubescent 
irista. The species should be common in England. 
lavicornis, E. This is the first of a group of large, thickly pubes- 
cent species, which have no strong black hairs round the edge of 
the scutellum ; it is distinguished from the others by the entire y 
yellow legs of the female, and by the yellowish antennae m both 
Boxes ; the male is smaller than grossa, with less pubescence, and 
entirely yellow tibi^ ; there are two males and three females m the 
Entomological Club collection, and Mr. Smith has given me a 
female captured by him in North Devon. 
chrysoco^a, Mg., is known by its entirely yellowish piibescence, 
without the least intermixture of black hairs; the tibi^ have a 
dark ring round the middle. I possess a male, purchased at Mr. 
Stevens' rooms in 1868. 
grossa, Eln., is distinguished by its large size, very thick pubescence, 
dark antenna., and black pubescence about the tip of the abdomen ; 
this black pubescence is very much less in the male than in the 
female. The species is not rare in woods in March. 
cMoris, Mg. This is the last of the thickly pubescent species, and 
generally has a few black hairs round the edge of the scuteUum. it 
has much less pubescence than the others, and is distmguished by 
black hairs on the front, thorax, &c., and by the luteous antenn.^ 
and a blackish spot about the middle of the tibi^ m the male. I 
believe it is not rare on Caltha palustris in April.
