428 TROGOSITIDA. 
28. Tenebroides iteratus, sp. n. 
Sat latus, minus parallelus, depressus, minus nitidus, piceus, elytris puncto humerali limboque rufescentibus ; 
dense punctatus, elytris striatis, interstitiis biseriatim punctatis ; antennis pedibusque rufis. 
Long. 7 millim. 
Hab. Mexico, Jalapa (Hége). 
Head moderately broad, coarsely punctate, unimpressed, rather dull. Thorax 
strongly transverse, sinuate at the sides and much narrowed behind; lateral margin 
only moderately thick ; anterior angles broad, acuminate, though but little produced ; 
the surface densely and coarsely punctate, slightly shining. FElytra not parallel, mode- 
rately deeply striate, the interstices flat, with rather fine biserial punctuation; the 
outer margins, especially behind, are reddish, and there is also a small humeral spot of 
the same colour. 
We have received only one example of T. iteratus; by means of T. longulus and it, 
T. repetitus and its allies are closely connected with 7. rufo-limbatus. 
29. Tenebroides rufo-limbatus. 
Tenebroides rufo-limbatus, Léveillé, Ann. Soc. Ent. Fr. 1888, p. 424°. 
Hab. Mexico !, Omilteme (H. H. Smith), Orizaba (Godman), Puebla, Cordova (Sallé), 
Jalapa (Hoge, M. Trujillo); Guaremaua, El Tumbador, Cerro Zunil (Champion). 
This is a variable species, the length of the specimens before me varying between 
62 and 10 millim.; the colour sometimes is shining black on the upper surface, 
without the rufescent margins from which the species derives its name. The rather 
-elongate, narrow, little-depressed form and the deep striation of the elytra, as well as 
the shape of the thorax, are apparently less variable, and permit the identification of 
the species. I have included as varieties four examples which may perhaps prove not 
to belong to it, viz. a very strongly punctate form with a red humeral spot, found at 
Jalapa by Hége; a pale ferruginous specimen with very deeply striate elytra, also 
found by Hége in the same locality ; and the two examples procured by Mr. Champion 
in Guatemala, which are very deeply striate, and have the lateral margins of the 
thorax a little more raised. 
30. Tenebroides longulus, sp. n. 
Parallelus, angustus, sat depressus, nitidus, piceus, capite prothoraceque nigricantibus, hoc ad latera, presertim 
anterius, rufescente ; fortiter punctatus, elytris profunde striatis ; antennis pedibusque rufis. 
Long. 63-73 millim. 
Hab. GuateMata, El Tumbador, Cerro Zunil (Champion). 
Head broad, coarsely punctate, not dull, almost unimpressed. Thorax moderately 
short, much narrowed behind, shining, coarsely punctate; lateral margin rather thick ; 
front angles much produced, acute. Elytra narrow and parallel, shining, deeply
