TROGOPHLCUS. 701 
A very distinct little species with points of resemblance to 7. miselius and T. puncti- 
pennis. Only one example was obtained. 
11. Trogophleus punctipennis. (Tab. XVIII. fig. 17.) 
Brevis, nigerrimus; pedibus fuscis, opacus ; elytris fortiter punctatis, subnitidis. | 
Long. 13 millim. 
Hab. GuateMa.a, San Gerénimo (Champion). 
Antenne short, the penultimate joints strongly transverse. Head narrow, scarcely at 
all constricted behind. Thorax narrow, rather broader than long; surface feebly 
uneven, very black and dull, not visibly punctate. LElytra rather longer than the 
thorax ; deeply, rather closely, and coarsely punctured. 
Four examples were obtained of this very distinct little Trogophleus. 
12. Trogophleus centralis. 
Latus, subdepressus, nigricans, pube breve erecta vestitus; antennarum basi pedibusque sordide rufis; pro- 
thorace basin versus curvatim impresso ; elytris sat fortiter punctatis. 
Long. 34 millim. 
Hab. Guatnmata, Cahabon, Lanquin (Champion); Panama, Caldera in Chiriqui 1200 
feet (Champion). 
Antenne a little thicker externally; third joint longer than the second, the penulti- 
mate joint about as long as broad. Thorax rather broader than the head, not much 
more than half the width of the elytra; the sides rounded in front, strongly narrowed 
behind; the surface somewhat coarsely but indefinitely punctured, the punctuation 
effaced on the middle, where there are two very obsolete depressions; the curved 
impression in front of the base large and distinct. The elytra are shining, much longer 
than the thorax, and coarsely punctate. 
This species is extremely similar to the European T. scrobiculatus, Er., but has a 
narrower thorax, as well as other slighter distinctions. Seven examples. 
13. Trogophleus triangulum. 
Niger, antennarum basi pedibusque testaceis, elytris rufis et ad suturam angulariter nigro-signatis ; pube minus 
obsoleta vestitus, sat fortiter punctatus ; prothorace basin versus profunde curvatim impresso. 
Long. 33 millim. 
Hab. Guatemata, Chiacam 2000 feet (Champion). 
This insect is allied to 7. centralis; in addition to the colour of the elytra it differs 
in being narrower, and also in other slight details. ‘The disc of the thorax is punctate 
as well as the sides, but has scarcely any trace of depressions; the suture of the elytra 
is black and the dark colour extends itself in a vague manner so as to form a triangle 
with its apex at the extremity of the suture; the pubescence of the hind body is 
remarkably distinct. One example.
