TENEBROIDES. 425 
21. Tenebroides alticola, sp. n. 
Sat elongatus, depressus, niger, nitidus ; capite prothoraceque crebre subtiliter punctatis; elytris subtiliter 
punctato-striatis, interstitiis obsolete punctatis; pedibus piceis, antennis tarsisque rufescentibus. 
Long. 9-10 millim. 
Hab. Guaremata, Totonicapam 8500 feet, Quiche Mountains 7500 feet, Duefias 
(Champion). 
In this species the thorax is narrowed behind and sinuate at the sides ; the anterior 
angles are broad and not elongate, the lateral margin moderately raised. The striation 
of the elytra consists of series of punctures nearly conjoined to form continuous strie, 
and the interstitial punctuation is very obscure; the striae are much obliterated behind. 
The punctuation of the ventral segments is coarse but not very dense, and there is 
apparently but little difference between the sexes in this respect. 
L. alticola differs from T. wndulatus by the rather less depressed and more parallel 
form and the less obliterated sculpture of the elytra. It is at first sight more similar 
to T. repetitus, but has the anterior angles of the thorax less produced and less acute 
and the striation of the elytra more obsolete behind. 
We have received five examples of 7. alticola. I also refer provisionally to it three 
specimens found in Mexico—by Hége at Esperanza and Jalapa, and by Sallé at Puebla, 
—which have the thorax a little more rounded at the sides in front and more narrowed 
behind, and the punctuation of the ventral segments rather less coarse. ‘Two specimens 
found by Blancaneaux on the R. Sarstoon in British Honduras have a deeper striation on 
the elytra and a coarser punctuation on the ventral segments. But it is. not advisable 
to treat these as belonging to distinct species. 
22. Tenebroides harpaloides. | 
Tenebroides harpaloides, Léveillé, Ann. Soc. Ent. Fr. 1888, p- 423%. 
Minus elongatus, depressus, niger, nitidus; capite prothoraceque crebre subtiliter. punctatis ;: elytris subtiliter 
punctato-striatis, interstitiis distincte biseriatim punctatis; antennis pedibusque rufis.. 
Long. 8-84 millim. 
Hab. Mzxico1, Jalapa (Hége). 
Head broad and short, somewhat closely punctate, with a small fovea on the middle. 
Thorax short and broad, rather finely margined at the sides, rounded at the anterior 
angles, which are broad and but little produced. Elytra with series of punctures 
which are nearly conjoined to form fine striz, and with a very distinct interstitial 
punctuation. Ventral segments extremely coarsely punctate. 
The two specimens received are male and female; the male has fine punctures 
mixed with the larger ones at the base of the first ventral segment and a small patch 
of similar punctuation at the outer edge of each of the three following segments. 
Though 7. harpaloides is one of a group of most closely allied forms, and although
