128 Mr. G. C. Champion’s Notes on 
A long series. This insect might, at first sight, easily 
be mistaken for a minute convex Histerid, or a Cercyon 
or Micropsephus. 
MELYRIDAE. 
CyMBOLUS. 
Cymbolus, Gorham, Biol. Centr.-Am., Coleopt. i, 2, p. 324 
(1886). 
Three species were included under this genus by Gorham 
—two from Guatemala and one from Mexico. A second 
was subsequently received by us from Mexico, and this is 
now described, as well as one from Brazil, this latter extend- 
ing the distribution of Cymbolus southward. The genus 
is related to Arthrobrachys, Solier. It belongs to the section 
Dasytinae. 
*Cymbolus elongatus, n. sp. 
Elongate, broad, rather depressed, shining; brown, the eyes and 
abdomen black, the rest of the under surface, mouth-parts, antennae, 
and legs ferruginous; thickly clothed above with very long, erect, 
fine, fulvous hairs, the under surface sparsely pubescent, the legs 
villose. Head sparsely punctate; eyes large, coarsely facetted ; 
antennae moderately long, joints 4-10 strongly serrate. Thorax 
short, nearly or quite as wide as the elytra, rounded at the sides, 
narrowing from a little before the base, the angles obtuse, the 
lateral margins crenulate; the surface impressed with coalescent 
umbilicate punctures between the irregular polished raised spaces, 
which are large and here and there confluent on the disc and small 
and more scattered towards the sides. Elytra elongate, somewhat 
depressed on the disc, subparallel in their basal half; closely, coarsely 
confusedly, punctate, the submarginal ridge narrowly separated 
from the marginal carina and bordered within by a row of slightly 
coarser impressions. Beneath finely punctate, the ventral segments 
much smoother down the middle and subequal in length. 
Length 7-7, breadth 3-3} mm. 
Hab. Mexico, Chilpancingo in Guerrero, 4,600 feet, 
(H. H. Smath). 
Two specimens, probably male and female, one of them 
having the thorax broader than the other. More elongate 
than C. castaneus and C. rufopiceus, differing also from the 
former in its ferruginous antennae and the very irregular
