426 TROGOSITIDA. 
I have seen only two specimens of it, I think it must certainly ‘be separated from 
T. alticola: the well-developed interstitial punctuation, in contrast with the fine stria- 
tion, the finer lateral margins to the thorax, and the coarse punctures on the ventral 
segments, being its chief distinctions. M. Léveillé has been good enough to lend me 
his unique type on which the species was founded, and I believe it to belong to the 
species I have described above, though the characters of 7. harpaloides are not quite 
so strongly marked in it as they are in our specimens. 
23. Tenebroides repetitus, sp. n. 
Elongatus, subparallelus, niger, nitidus, subdepressus, subtus pedibusque piceis, antennis sordide rufis; capite 
prothoraceque crebre punctatis; elytris regulariter striatis, interstitiis biseriatim punctatis. 
Long. 11-13 millim. 
Hab. Mexico (ex coll. Sturm), Jalapa (Hoge), Cordova (Sallé); Guatemaua, Capetillo, 
near the city of Guatemala (Champion). 
Head dull, moderately closely punctate. Thorax narrowed behind, not sinuate at the 
sides, the hind angles slightly prominent, the lateral and basal margins almost equally 
thick throughout, the surface shining, rather coarsely and closely punctate. LElytra 
subparallel, rather elongate, marked with distinct strie which are not obsolete at the 
extremity, and at the sides are represented by series of remote punctures, the interstices 
broad, flat, and distinctly biseriately punctate. Under surface piceous; ventral seg- 
ments very densely punctate; in the male the punctuation at the sides dense and 
minute over a considerable area. 
Mr. Champion met with a good series of this insect at Capetillo, and these examples 
do not vary much, except that in some of them the head has a small fovea which is not 
present in others. The specimens from other localities are very few in number, and 
vary much; but I cannot distinguish them as species in a satisfactory manner, and 
prefer to treat them as varieties of one only. 
24, Tenebroides zunilensis, sp. n. 
Depressus, sat elongatus, piceus, nitidus; capite prothoraceque nigricantibus, dense punctatis, hoc lateribus 
piceis, illo foveolato ; elytris striatis, interstitiis biseriatim punctatis; antennis pedibusque rufis. 
Long. 10 millim. 
Had. Guaremata, Cerro Zunil, Mirandilla (Champion). 
Head shining, closely and coarsely punctured. Thorax rounded at the sides and 
strongly sinuate behind; lateral margin moderately raised ; front angles rather broad, 
less acute than usual; the surface closely and deeply punctured. LElytra with regular 
distinct striee, and with very distinct biserial punctuation on the interstices. Ventral 
segments closely punctate. 
This species is distinguished from its allies by the thorax being more sinuate behind, 
and the elytra evidently striate, with very little trace of punctuation in the strie. As
