GEO. H. HORN, M. D. 
The last ventral segment is broadly triangularly eniarginate. The 
antennje do not extend much beyond the hind angles of the thorax, 
and are similar in the sexes. 
The female is entirely of a uniform blue above and beneath, some- 
times quite green, the last ventral entire. 
For the opportunity of recording the sexual differences I am in- 
debted to the National Museum at Washington, where numerous 
specimens were received from San Diego, Cal. 
tS. Sallei Horn was described from a female with scarcely any 
trace of metallic siuTace color. The elytra are similar in color to 
Mas % , except that there is a darker oblique vitta extending from 
the humeral umbone nearly to the sutural angle. The head and 
thorax are darker in color. 
The oblique impression of the thorax, on which I laid some stress, 
seems not to have great value, as it seems to be a variable quantity 
in ketm. The claws of Sallei are, however, much less distinctly 
cleft, and seem rather to be provided with a small tooth at middle 
after the style of some Lachnostern^e. 
This species was collected at Mariposa, Cal., by Mr. Alphonse 
Thevenet. 
Mr. F. Blanchard is quite correct in recording the presence of the 
“ ante-coxal piece” of the metasternum in both Schizopus and Dys- 
taxia. The presence of this piece seems to be quite characteristic of 
the Buprestidse. In the genus Lissomus, of the Throscidse, there is 
no trace of this piece, so that by the fortunate discovery by Mr. 
Blanchard we have a more ready method of separating the latter 
family from the Buprestidte than previously existed, Lissomus having 
always been an annoying element. 
While the presence of the “ ante-coxal piece” and its modification, 
or entire absence, plays an important part in the Adephagous series, 
it would hardly have been suspected to have similar utility in a series 
so remotely separated as the Serricornia.
