732 STAPHYLINIDA. 
This species has a very broad head, and the groove near the eye is very deep and 
distinct and rather strongly curved. It differs greatly in colour from E. breviceps, but 
the sculpture and other details are nearly identical. 
10. Eleusis mixta. 
Capite, prothorace pectoreque nigris; elytris flavis, apice fusco; antennis femoribusque fuscis, tibiis tarsisque 
testaceis, abdomine fusco-testaceo ; nitida, capite crebre punctato. 
Long. 4 millim. 
Hab. Mexico, Cordova (Sallé); Guatemaua, Cerro Zunil, San Gerdénimo, Purula 
(Champion). 
Differs from E. scita in the more obscure colour, and in the distinct punctuation of 
the head; the elytra are indefinitely infuscate behind; and the hind body, though of a 
yellowish colour, is always more or less infuscate along the middle. 
11. Eleusis insignis, (Tab. XIX. fig. 19.) 
Nigra; antennis, pedibus abdomineque rufis, hoc medio fusco; elytris flavis, sutura apiceque fuscis; capite 
latiore, fortiter punctato. 
Long. 53 millim. 
Hab. Guatemata, Quiche Mountains 7000 to 9000 feet (Champion). 
Head short, very broad; surface uneven, coarsely punctate; the juxta-ocular groove 
very broad, rather indefinite. Thorax broad, greatly narrowed behind, denticulate at 
the side behind the middle; the surface rather uneven, canaliculate on the disc, and 
with rather numerous large punctures. Elytra very finely punctulate. One example. 
EUMALUS. 
Corpus depressum, elongatum. Prosternum valde elongatum. Abdomen tenuissime, vix perspicue, mar- 
ginatum. 
This genus must certainly be placed next to Kleusis, though it is distinguished by 
numerous characters. The prosternum is extremely elongate, the supernumerary piece 
or trochantin extending far forward and uniting with the prosternum by a very visible 
suture; this piece is somewhat depressed so as to form an imperfect groove for the 
reception of the femur, where the leg is flexed on the prosternum. The head has well- 
marked antennary tubercles, and the front margin of the pronotum is tuberculate. The 
mandibles, though small, are prominent like those of Eleusis. ‘The maxillary palpi are 
similar to those of Hleusis, except that they are shorter, with the penultimate joint 
rather thicker, and the terminal joint rather smaller. The front coxe are small and 
subglobular, and not exserted, and situated quite at the back of the elongate prosternum. 
The tarsi are 5-jointed, the four basal joints quite small and together not quite equal 
in length to the terminal joint. 
The peculiar development of the trochantin I have described in connection with
