270 INSECTA. 
16,25. Russet, with yellow or whitish spots or streaks on the 
abdomen. It sometimes varies, the thorax being occasionally 
brown, and the abdomen maculated with the same colour. It 
is very rare in the environs of Paris, but common in the depart- 
ment of Calvados. It is the Mouche armée odorante (Strat. 
olens) of the Tableau Elémentaire de |’Histoire Naturelle des 
Animaux. It diffuses a strong odour of Melilot sometimes even 
after death(1). 
Benris, Lat. Meig. 
Where the antennz are a little longer than the head, with their 
two first joints of equal length, and the third forming an elongated 
cone. The scutellum exhibits from four to six spines(2). 
CypHomyia, Wied. 
Where the antennz are still more elongated, with the third joint 
longer than the second; the third is linear and compressed. The 
scutellum has two spines(3). 
Those have antennz which throw out on each side, near the mid- 
dle, three or four linear, hairy threads, the superior ones silky; they 
are almost setaceous near the extremity. The scutellum has four 
teeth. 
Pritopacty.Lus, Wied. 
They have the general appearance of a Beris and a Cyphomyia(4). 
In the third section—Stratiomydes, Lat.—we also find an- 
tenn consisting of three joints, the last of which, exclusive of 
(1) See Lat., Fab., Meig. and Macq. .

(3) Wied., Anal. Entom., 13, fig. 4. 
The genus Platyna of this naturalist, established and figured in the same work, 
is wholly unknown to me. The Insect, on which he has formed it, has the port of 
a Berisand a Cyphomyia. The antennz are equally long and filiform, with the two 
first joints elongated and cylindrical, and the last, judging from his figure of one 
of those organs, without rings. The scutellum has but one spine.
