20° PSELAPHIDA. 
EUPHALEPSUS. 
Euphalepsus, Reitter, Verh. z.-b. Ges. Wien, xx. p. 378 (1882). 
This genus, though allied in many respects to Batrisus, is essentially distinct by the 
structure of the palpi. It comprises as yet only three Brazilian species in addition to 
those found in our region ; one, recently described by Reitter as L. longicornis, has had 
no locality indicated, but it is not, I believe, from our region. 
1. Euphalepsus globipennis. 
Euphalepsus globipennis, Reitt. 1. c. p. 379°. 
Hab. Mexico, San Marcos (Bilimek 1, mus. Vindob.). 
We have not received this species. 
2. Euphalepsus centralis. 
Brevis, convexus, sanguineo-castaneus, nitidus, pube erecta vestitus; elytrorum basi et humeris marginato- 
elevatis; antennis sat elongatis, articulis nono et decimo in latitudine et longitudine subzqualibus. 
Long. 2 millim. 
Hab. Guatemata, San Gerénimo, Quiche Mountains 7000 to 9000 feet (Champion). 
Antenne with joints 3-8 differing little from one another; the ninth joint consider- 
ably larger and about as long as broad, the tenth similar to the ninth, the terminal joint 
rather longer than the preceding two together. Head small; with two short thick 
antennal tubercles, and behind each of these obscurely foveolate. Thorax small, convex, 
with a deep transverse sulcus in front of the base, the extremity of the sulcus con- 
nected with a short deep longitudinal impression on each side. Elytra broad, convex, 
the base margined, the shoulders elevated; the humeral elevation not continued 
backwards along the sides, the basal margin crenulate owing to the three or four punc- 
tures or minute fovez which exist on each side; without discoidal stria, the sutural 
stria fine; the pubescence very distinct, but the punctuation extremely feeble. Hind 
body very short, convex, forming in profile a curve almost continuous with the elytra. 
Legs rather slender. 
Only one example was found in each locality; they are apparently male and female, 
though the differences are but slight: each has the metasternum foveolate at the 
extremity. The male, from San Gerénimo, has a very minute patch of pubescence on 
the hind margin of the intermediate femur near the base, the middle tibia slightly 
denticulate inwardly just below the middle, and the hind tibia with a very minute 
inflation of its superior face below the middle. The female is remarkable on account 
of the existence of a conical projection of the dorsal surface of the hind body at the 
extremity.
