various Central American Coleoptera 167 
[Lorelus rugifrons, n. sp. 
Elongate, shining, obscure ferruginous, the legs testaceous, clothed 
with long, fine, yellow hairs; the upper surface closely, confusedly 
punctate, the punctures on the elytra much coarser than those on 
the thorax, those on the head confluent. Head shallowly, trans- 
versely grooved behind the epistoma, the antennary orbits feebly 
developed; eyes transverse, rather small; antennae stout, barely 
reaching the base of the thorax, joint 3 longer and stouter than 2, 
4-8 transverse, 9-11 moderately thickened. Thorax convex, tra- 
pezoidal, rather small, very narrowly margined, the anterior angles 
obtuse, the hind angles rectangular. Elytra moderately elongate, 
depressed, much wider than the thorax, widening posteriorly. Legs 
short. 
Length 4mm. (? 9.) 
Hab. Brazit, Rio de Janeiro (coll. Fry, in Mus. Brit.). 
Two specimens. Distinguishable by the rugose head; 
the small antennary orbits; the stout antennae, with 
thickened third joint and moderately dilated club; the 
trapezoidal, convex, feebly margined thorax; and the 
pubescent, uniformly coloured surface. L. rugifrons 
approaches Lorelopsis pilosus, but it has the thorax much 
more widened anteriorly, the antennae stouter, and the 
penultimate joint of the tarsi smaller. | 
*Lorelus trapeziderus, n. sp. (Plate IV, fig. 12, 9.) 
Elongate, depressed, varying in colour from piceous to testaceous, 
shining, clothed with long fine yellow hairs; the upper surface closely 
confusedly punctate, the punctures on the elytra coarser than those 
on the head and thorax. Head transversely grooved in front, the 
antennary orbits well developed; eyes transverse; antennae 
moderately stout, joints 2 and 3 equal in length, 4-8 short, 9-11 
abruptly widened. Thorax trapezoidal, nearly as long as broad, 
truncate in front, sharply margined at the sides and also feebly 
margined at the base, the anterior angles prominent, the hind angles 
rectangular. Elytra moderately elongate, a little wider than the 
thorax, widening posteriorly. Legs short; penultimate tarsal joint 
somewhat strongly lobed. 
Length 34 mm. (9.) 
Hab. GuatTEMALA, Senahu in Alta Vera Paz (Champion), 
Trece Aguas (Barber and Schwarz, in U.S. Nat. Mus.). 
Hight specimens. Differs from L. rugifrons in its less 
rugose, broader head; the prominent antennary orbits;
