QUEDIUS. 329 
§1. Gene with a raised margin; elytra evenly and regularly punctate and pubescent. 
1. Quedius advena. 
Niger; capite thoraceque subviridescentibus, elytris viridescentibus, antennis pedibusque fuscis, tarsis fusco- 
testaceis ; capite suborbiculato, 
Long. 8 millim, 
Hab. Mexico, Las Vigas (Flohr). 
Antenne rather short; basal joint pitchy red; second and third joints nearly black, 
except that the second is red at the base; tenth joint as long as broad. Head broad, 
the eyes extending more than three fourths of the length of the sides; four coarse 
punctures in a transverse line near the front of the eyes, the inner puncture touching 
the margin of the eye. Thorax nearly as long as broad, a little narrowed in front. 
Scutellum smooth, without any punctures. Llytra rather longer than the thorax, 
somewhat sparingly and not very finely punctured. Hind body black, feebly metalles- 
cent, closely, very finely punctate. The front tarsi are rather broadly dilated in each 
of the sexes. 
This insect appears very closely allied in structure to the European Q. attenuatus ; 
but the rather elongate terminal joint of the maxillary palpus is very slender and 
acuminate. Mr. Flohr has sent nearly a dozen examples. 
§ 2. Gene without raised margin ; elytra evenly and regularly punctate and pubescent. 
2. Quedius leticulus. (Tab. VIII. fig. 3.) 
Angustulus, nigerrimus; antennis pedibusque testaceis, elytris lete eneo-viridibus, abdominis apice late rufo. 
Long. 73 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
This insect is similar in size and shape to the European Q. attenuatus. The antenne 
are short and stout, with joints 5-10 transverse; palpi yellow. Thorax but little 
rounded at the sides, about as long as broad, very black and shining. Elytra slightly 
longer than the thorax, sparingly and finely punctate; scutellum sparingly punctate. 
Hind body very black, with the terminal styles, the last segment and a portion of the 
preceding segment red, sparingly but not finely punctate. 
Only one specimen has been found; it is apparently a female, though the front tarsi 
are broadly dilated. 
8. Quedius championi. (Tab. VIII. fig. 4.) 
Niger; antennarum basi pedibusque testaceis, elytris brunneo-testaceis, ad suturam late fuscis, abdomine fulyo- 
pubescente, segmentorum marginibus posterioribus ferrugineis, ultimo ex parte majore rufo, 
Long. 7 millim. 
Hab. Guatemata, San Gerénimo 3000 feet, Purula (Champion).
