various Central American Coleoptera. 63 
long, rather slender, subserrate, 11-jointed, 3-5 elongate, 6-11 grad- 
ually becoming shorter, Thorax short, rapidly and _ obliquely 
narrowing from the outwardly directed prominent hind angles, 
deeply bisinuate at the base and also sinuate at the sides before the 
middle, densely, minutely punctate. Elytra oblong, a little wider 
than the thorax, rounded at the sides posteriorly ; densely, rugulosely 
punctate, and with several longitudinal ridges on the disc and also 
one near the outer margin. Beneath very densely punctate; 
fifth ventral segment broadly emarginate, leaving the sixth in part 
visible, the latter triangularly excised at the apex, the seventh 
narrow, subcylindrical, rounded at the tip. Legs long; tibiae 
slender; tarsi with joints 1-4 short, somewhat thickened, 4 small, 
5 very slender, longer than the others united, the claws very long. 
Length 4, breadth 23 mm. 
Hab. Mexico (Truqui, in Mus. Brit. ex. coll. Fry). 
One specimen, injured by pinning. The thorax has a very 
deep transverse sulcus at the base, but this is clearly 
accidental. It is just possible that P. palpalis is the male 
of P. haldemani, but this is hardly likely to be the case. 
PSEPHENOPS. 
Psephenops, Grouvelle, Notes Leyden Mus. xx, p. 44, 
(1898). 
This genus is ada upon a single species, P. smithi, 
Grouv., from the Antillean islands of Grenada and St. 
Vincent, of which the male only is known, this having a 
very large, elongate, acuminate-ovate fourth joint to the 
maxillary palpus. The Guatemalan species now added, 
the female only of which is known, has the second tarsal 
joint more strongly and abruptly lobate, with a long slender 
basal portion, the antennae much longer, etc. The genus 
Psephenops affords a connecting link between the Parnidae 
and Dascillidae. 
*Psephenops grouvellei, n. sp. (Plate III, figs. 2, 2a, 9.) 
Q. Oblong, widened posteriorly, depressed, moderately shining, 
densely pubescent; dark brown, the front of the head, the antennae 
and femora at the base, the scutellum, the margins and base 
of the elytra, and the under surface, testaceous; the entire surface 
densely, minutely punctate. Head concave and bifoveate between 
the eyes, the latter large; antennae moderately long, 11-jointed, 
1 and 2 stout, 1 elongate, curved, 2 short, subglobose, 3-11 feebly
