34 PSELAPHIDA. 
Subfam. PSELAPHIN ZA. 
| PSELAPHUS. 
Pselaphus, Herbst, Natursyst. bek. ausl. Ins. Kaf. iv. p. 106 (1792). 
This distinct genus is widely distributed over the world, and comprises at present 
about seventy described species. 
1: Pselaphus longiceps. (Tab. I. fig. 18.) 
Latus, castaneus, elytris sanguineis; capite antennarumque articulo basali elongatis. 
Long. 24 millim. 
Hab. Guatemata, Paso Antonio (Champion). 
Head elongate, dull, depressed between the eyes. Antenne with the first joint as 
long as the following four joints together; the terminal joint elongate, nearly equal in 
length to the preceding four united. Palpi very elongate; second joint very long and 
slender, rather tortuous, and with a slender apex; third joint small; fourth joint with 
delicate basal stalk, about equal in length to the slender apical dilatation. Thorax 
slender, much rounded at the sides, without impressions. Elytra gradually narrowed 
from the apex to the base, shining red, with well-marked sutural stria. Prosternum in 
front of the cox densely covered with glandular pubescence; its hind margin and the 
base of the hind body each with a band of similar pubescence. _ 
The unique example of this very distinct species is probably a female. 
PSELAPHOMORPHUS. 
Pselaphomorphus, Motschulsky, Etudes ent. 1855, p. 15, tab. f. 7. 
Nothing I believe is known as to this genus beyond Motschulsky’s imperfect figure 
and few words of description ; but the insect is apparently very different from Pselaphus 
by its palpi. Possibly these organs have been mutilated.
