QUEDIUS. | 335 
The only individual found is a very decayed and mutilated female; probably in the 
fresh state the front of the head and base of the antennz may be piceous; the labrum 
is very large. 
15. Quedius protensus. 
Niger, nitidus ; antennarum basi, partibus oris pedibusque anterioribus rufis ; elytris rufo-sanguineis, pedibus 
posterioribus piceis, tarsis rufis; capite orbiculato ; elytris fere brevioribus quam prothorax, punctis non- 
nullis, seriatis, conspicuis impressis; abdomine magno, sat evidenter versicolore, crebrius equaliter punctato. 
Long. 14 millim. 
Hab. Guatemaa, Duefias (Champion). 
Antenne short, red at the base, darker externally; the eighth and ninth joints 
scarcely transverse. The elytra, of a dark red colour, have the arrangement of punctures 
seen in Q. verecundus and other allies, but the punctures are not numerous, there being 
only four or five along the suture ; the posterior one or two of these are indistinct, and the 
last of them is far in front of the hind margin ; the intra-humeral series is irregular and 
consists of five or six punctures. The hind body is larger than in the allied species, 
and is rather closely and coarsely punctate; the basal segment is without impunctate 
space; the hind margin of the penultimate segment is narrowly reddish, as is the 
extreme base of the apical segments, and also the terminal styles. 
Only a single mutilated individual has been found. 
16. Quedius rivorum. 
Niger, nitidus; antennis, partibus oris pedibusque testaceis ; elytris sanguineo-rufis circa scutellum nigris, 
punctis seriatis magnis impressis; abdomine subversicolore, crebrius punctato, apicem versus rufo 
variegato. 
Long. 9-10 millim. 
Hab. Guatema.a, near the city (Champion). 
Var. Capite anterius latius rufescente. 
Hab. Mexico, Juquila (Sailé). 
Antenne short, a little thicker externally, the three penultimate joints transverse. 
Head orbiculate, not so much constricted at the neck as in most of the allied species; 
the eyes, however, very prominent, the front margin vaguely and narrowly rufescent. 
Elytra hardly so long as the thorax, polished, of a dark red colour, with a black patch 
round the scutellum, and with the outer margin black; the serial punctures are large 
and conspicuous, and disposed as in the allied species; those of the sutural series are not 
so large as the rest. The hind body is black, rather closely punctate ; the penultimate 
segment with a conspicuous red cincture behind; the extreme base of the apical 
segment also reddish as well as its hind margin; the terminal styles more or less 
infuscate red. | 
The male has a large depression at the tip of the last ventral plate, and the hind
