TENEBROIDES. 427 
Jalapa and Toluca (Hége) and Omilteme in Guerrero (H. H. Smith), that differ from 
the typical form in being less dull, in having the elytra less obsoletely striate, and 
the lateral margin of the thorax finer. It is very doubtful whether they are really 
conspecific with 7. facilis, but they do not agree sufficiently inter se to justify me in 
separating them. 
11. Tenebroides spectator, sp. n. 
Elongatus, sat depressus, nitidus, nigerrimus, antennis tarsisque rufis; capite prothoraceque crebre fortiter 
punctatis, hoc basin versus angustato, lateribus posterius sinuatis ; elytris striatis, interstitiis obsolete 
punctatis. 
1_101 milli 
Long. 93-104 millim. 
Hab. Guatemata, San Gerénimo (Champion). 
Resembles 7. repetitus of the second division rather than any species of the first 
division; it has much smaller eyes and a smaller antennal club than 7. deceptor and 
T. celatus. Wead dull, somewhat convex, rather closely punctate, without fovea. 
Thorax punctured like the head, moderately strongly margined at the sides, much 
narrowed behind and sinuate near the base, the hind angles slightly prominent 
externally, nearly rectangular; basal margin quite distinct in the middle. FElytra 
moderately deeply striate, rather shining, the punctuation of the interstices indistinct. 
Ventral segments very coarsely punctate. Two specimens. 
12. Tenebroides anceps.

Hab. Mexico}, Jalapa (Hoge, M. Trujillo); Guatemata, Sabo (Champion). 
The peculiar sculpture of the elytra distinguishes this from all other species of the 
genus: the usual strie are here replaced by fine elevated lines, which are here and 
there minutely interrupted, and are shining; the broad interstices are quite dull, and 
bear a well-marked biserial punctuation. The club of the antenne is rather large, and 
the ares of sensitive surface very large. 
Only one example was obtained in Guatemala; it is a variety of rather smaller size, 
with the biserial interstitial punctuation of the elytra remarkably definite, the punc- 
tures being elongate and almost connected so as to form strie. It may perhaps prove 
to belong to a distinct species. 
The small series of seven examples from Mexico does not exhibit any variation. 
13. Tenebroides yucatanicus.
