TENEBROIDES. 429 
striate, the interstices a little convex, with a remote biserial punctuation. Ventral 
segments coarsely punctate ; in the male with much fine punctuation on the side of 
each segment. ‘Two specimens. 
This insect is allied to 7. repetitus, but it is not so large, and differs by the important 
character that the lobes of the club of the antenne are considerably smaller. From 
T. rufo-limbatus, which at first sight it nearly resembles, it differs in its broader 
thorax, with thicker lateral margins and more acute anterior angles, and its rather 
broader head. 
31. Tenebroides auriculatus, sp. n. 
Minus elongatus, subdepressus, rufo-piceus, supra piceus, limbo plus minusve evidenter dilutiore ; capite den- 
sissime fortiter punctato; elytris profunde striatis, interstitiis fere impunctatis. 
Long. 53-7 millim. 
Hab. GuateMata, El Tumbador, El Reposo, Zapote (Champion). 
Head depressed in front, very coarsely punctate, the punctures more or less elon- 
gated and confluent. Thorax short, much narrowed behind, coarsely punctate, 
shining; lateral margin moderately coarse; anterior angles much produced, broad, 
subexplanate, less acute than usual. Elytra subparallel, deeply striate, the biserial 
interstitial punctures remote and very fine. Prosternal process moderately coarsely 
punctate. Nine examples. 
This species bears some resemblance to the smaller examples of T. rufo-limbatus, but 
is considerably smaller, and is readily distinguished by the punctuation of the head and 
by the different shape of the front angles of the thorax. In the male the punctuation 
of the ventral segments is much finer than it is in the female.

Tenebroides bonvouloiri, Léveillé, Ann. Soc. Ent. Fr. 1888, p. 424°. 
Hab. Mexico!, Jalapa (Hoge), San Andres (Sallé); Guatemata, Senahu, Chaco} 
(Champion), Coban (Conradt). 
Var. chontalensis. Capite anterius densissime ruguloso-punctato. 
Hab. Nicaracua, Chontales (Janson). 
To judge from the small series we have received this must be a very variable species ; 
the specimens are, however, only one or two in number from each locality. The length 
varies between 44 and 73 millim. In some of the individuals the basal line of the 
thorax is very nearly, if not quite, interrupted in the middle. 
33. Tenebroides lucidus, sp. n. 
Angustus, parallelus, piceus, supra eneus, nitidus, antennis pedibusque rufis; elytris profunde striatis. 
Long. 7-8 millim. 
Hab. Panama, Volcan de Chiriqui (Champion).
