than the thorax, parallel in their basal half. Beneath coarsely and 
closely, the ventral segments sparsely and finely, punctate; pro- 
sternal process narrow. 
Length 23-3 mm. (? 3.) 
Hab. GuatTEMALA, Livingston, Atlantic coast (Barber 
and Schwarz, in U.S. Nat. Mus.). 
Four specimens. Two females found by Mr. Schwarz 
at Tampico, in N.E. Mexico, may belong to the same 
species; they are larger and broader than the others, and 
have the epistoma immarginate in front and the prosternal 
process broader. More convex than the Antillean L. 
brevicornis, Ch., the thorax subquadrate (g), the eyes a 
little smaller. The simple posterior tibiae, etc., separate 
L. angustulus from L. curvipes. This insect might easily 
be mistaken for a Cryptophagid. 
*Lorelus exilis, n. sp. (Plate IV, fig. 11.) 
Elongate, very narrow, depressed, shining, finely pubescent ; 
varying in colour from piceous with the elytra castaneous to wholly 
rufo-testaceous; the upper surface densely, confusedly punctate, 
the punctures on the elytra a little coarser than those on the head 
and thorax. Head deeply transversely grooved behind the epistoma, 
the groove reaching the antennary orbits (in one specimen reduced 
to two lateral impressions); eyes small, rather prominent; antennae 
barely reaching the base of the thorax, joints 4-8 strongly transverse, 
9-11 moderately widened. Thorax as long as broad, subquadrate, 
very narrowly margined, the sides obliquely constricted before the 
rectangular hind angles; the disc with a shallow, transverse, arcuate 
depression before the base, on either side of which a basal fovea is 
just traceable. Elytra elongate, a little wider than the thorax, 
subparallel in 3, broader and slightly widened posteriorly in 9. Legs 
very short. 
Length 17-2} mm. 
Hab. GuatEMALA, El Tumbador and Las Mercedes, 
Pacific slope (Champion), Trece Aguas in Alta Vera Paz 
(Barber and Schwarz, in U.S. Nat. Mus.). 
Six examples, assumed to include both sexes. A very 
small, narrow, pubescent form, with the head transversely 
grooved across the front, the eyes small, and the thorax 
oblongo-quadrate. In the single specimen from Vera Paz 
the transverse frontal groove is interrupted at the middle,
