670 Mr. G. C. Champion on Central American Coleoptera. 
repose between the somewhat widely separated anterior 
coxae. 
Fam. DASCILLIDAE. 
Scirtes planicornis, n. sp. 
Rotundate-elliptic, somewhat depressed, shining; pitchy-black, 
the apices of the femora, the tibiae, and tarsi testaceous, the antennae 
testaceous, becoming gradually infuscate towards the apex; finely 
pubescent. Head, prothorax, and scutellum closely, very minutely, 
punctate; head broad, the eyes large; antennae about as long as 
the body, joints 2 and 3 short, subtransverse, equal, 4-10 very 
elongate, flattened, considerably widened, becoming narrower to- 
wards the apex, 4 shorter than 5; prothorax short, convex, narrowing 
from the base, sharply margined; elytra thickly, finely punctate, 
the punctures much coarser than those on the prothorax, narrowly 
margined at the sides, the subhumeral callosities prominent. 
Length 23, breadth 14 mm. (3?) 
Hab. GUATEMALA, San Gerdnimo in Baja Vera Paz 
(Champion : Mus. Brit.). 
One specimen, sent to the late M. Jacoby as a Halticid, 
and thus overlooked, till detected by Mr. O. E. Janson 
when the collection of that author passed into his hands. 
Amongst the 21 species of Scirtes enumerated by me from 
Central America in 1897 (Biol. Centr.-Am., Coleopt., in, 
1, pp. 606-617), S. planicornis can only be compared with 
S. longicornis, from Panama, which has a minute third 
antennal joint, etc.* 
* The recently described S. championi, Picado, from Costa Rica, 
again, is a very different form.
