various Central American Coleoptera. 67 
Three specimens, probably including both sexes. Nar- 
rower and blacker than A. horni and A. laevis, Matth., and 
very like a small Agathidiwm. From the much smaller 
A. minor, the relatively broader thorax will sufficiently 
distinguish A. melas. One of the Jalapa examples was 
labelled Agathidium estriatum by Matthews, but it does 
not agree with Horn’s description of that N. American 
species. 
Aglyptonotus matthewsi, n. sp. 
Aglyptus laevis, Matth., Biol. Centr.-Am., Coleopt. ii, 1, 
p. 79 (1887) [nec Leconte]. 
The Chiriqui insect identified and described by Matthews 
as A. laevis, Lec., has obviously nothing to do with the 
N. American species, as a glance at Horn’s figures (Trans. 
Am. Ent. Soc. vii, pl. 7, figs. 15, 15a) will show, and a new 
name is therefore required for it. A. laevis has much 
shorter antennae. There are one or two forms in the lesser 
Antilles very closely allied to, if not actually conspecific 
with, A. matthewsi. 
CoLENIS. 
Colenis, Erichson, Nat. Ins. Deutschl. iii, p. 82 (1845); 
Matthews, Biol. Centr.-Am., Coleopt. ii, 1, p. 86. 
Matthews enumerated two species of this genus from 
Central America, both minute forms; a third has since been 
detected in our collection. 
*Colenis phalacrovdes, n. sp. 
Short ovate, convex, shining, obscure ferruginous, the antennae 
and tarsi testaceous, the antennal joints 7-10 sometimes slightly 
infuseate. Head faintly alutaceous; antennae with joints 3-6 
slender, 3 elongate, obconic, as long as 2, 4-6 small, subequal, 7-11 
widened into a loose 5-jointed club, 7 trapezoidal, nearly as wide as 
9, 8-10 strongly transverse, 8 small, 11 acuminate-ovate; thorax 
almost smooth; elytra with somewhat sinuous rows of minute 
punctures, the interstices sparsely, transversely strigose, and with 
a short sutural stria on the apical declivity. 
Length (excl. head) 1-12, mm. 
Hab. GuAaTEMALA, Zapote, Pacific slope (Champion). 
Three specimens. Smaller than C. punctulata, Matth., 
from Panama, ferruginous in colour, the antennae shorter, 
the proportions of the joints somewhat different, the ninth
