13. Staphylinus tempestivus. 
Niger, opacus, nigro-tomentosus ; abdomine in medio bifariam nigro-maculato ; capite in medio obscure rufo- 
bimaculato ; alis violaceo-nigrinis. 
Long. 26 millim. 
Hab. Mexico, near the city (Forrer). 
This insect is very similar in form to S. maculosus, and is of the size of the smallest 
individuals of that species, but is readily distinguished by the intense black colour. 
The antennz are black, with the terminal joint rusty colour. The head is narrowed in 
front, the eyes do not occupy one half of the length of the sides, it is very densely and 
coarsely punctured, and has two small obscure ferruginous spots on the middle. The 
thorax is punctured like the head, and has a well-marked smooth line along the middle. 
The elytra are dark black, and have a few grisescent atoms sprinkled amongst the 
pubescence. The hind body is rather sparingly and indistinctly punctured, very deep 
black, with a few white atoms amongst the pubescence on the upper surface; on the 
under surface these atoms are replaced by griseous hairs amongst the pubescence, 
and across the extreme base of the penultimate segment there is a band of grisescent 
pubescence. The wings in colour and pigmentation are almost exactly similar to those 
of S. atrox. 
I have seen only a single male.

Hab. Norta America }2,—Mexico (ex coll. Saunders). 
The only individual from our region known to me is a well-marked variety with 
fuscous pubescence on the thorax, and almost without atoms of golden tomentum on 
the hind body, with the basal joint of the antenne black on its upper face, and with a 
greater extension than usual of the black colour of the legs.

maculato; corpore subtus aureo pubescente, pectore anterius, prothorace et capite ex parte majore nigri- 
cantibus ; antennarum basi pedibusque (cum coxis) testaceis.
