various Central American Coleoptera. 151 
One pair, the sexual differences in the antennae of which 
were noted by Gorham. The double system of punctuation 
is like that of #. pubescens, which is a much larger, duller, 
and more densely pubescent form. The types of the 
latter, two females from Chiriqui and Vera Paz respectively, 
do not agree very well inter se, but as the Vera Paz specimen 
is not in good condition it must be included under £. 
pubescens for the present. EH. dejeani, Pic, from Teapa, 
Mexico, is probably an allied form. 
THAPTOR. 
Thaptor, Gorham, Biol. Centr.-Am., Coleopt. i, 2, pp. 205 
(1883), 348 (1886). 
This genus Thaptor, according to Mr. Fall [Trans. Am. 
Ent. Soc. xxxi, p. 219 (1905)], was created quite unneces- 
sarily by Gorham; nevertheless it is convenient to retain 
itfor the various Central American forms described by that 
author. These species, it is true, have the antennae and 
sterna formed as in Hupactus (= Lioolius, Gorh.) ; but they 
are very different in general facies, having the dense double 
system of punctuation and close pubescence of Cathorama. 
They are rather large, elongate, subfusiform, or broad 
oblong, insects, with setose antennae, and a single sub- 
marginal stria running down the apical half of the elytra. 
Fall’s synonymy is also quoted by Pic [L’Hchange, xx, 
p- 31 (1904) ], who had just before added (loc. cit. pp. 18, 19) 
three species to the genus Thaptor—one from Chile, one 
from Australia (!), and one from Mexico. The last 
named, 7’. mexicanus, is clearly nothing but 7. oblongus, 
Gorh., the only difference mentioned being “ moins 
brillant.” The four Central American species may be 
tabulated thus :— 
Elytra without definite rows of punctures 
at the sides preceding the sub- 
marginal stria. 
Body somewhat fusiform. 
Species larger; setae on inner edge of 
antennal joints 2, 3, 5, 7 very long; 
under surface more array eee aE bese us, Gorh.
