434 TROGOSITID. 
extended in the anterior direction, so that it forms with the one on the opposite elytron 
a fascia interrupted at the suture. 
44. Tenebroides sericatus, sp. n. 
Parvus, sat latus, subdepressus, parum nitidus, eneo-niger, antennis rufis, pedibus testaceis; elytro singulo 
macula parva testacea notato. 
Long. 5 millim. 
Hab. Guatemana, Cerro Zunil (Champion). 
Antenne reddish-yellow, with rather large club. Head and thorax dull, somewhat 
finely punctate, the latter very strongly transverse, slightly picescent about the 
margins. Elytra rather dull, with regular series of moderately large punctures, and 
with a scarcely visible interstitial punctuation ; each with an indefinite yellow spot 
placed in front of the middle. One specimen. 
I separate this from 7. fenestratus on account of the rather larger size of the joints 
forming the club of the antenne ; except for this character I should have treated the 
insect as an extreme variety of that species. T. sericatus has, however, the thorax 
very short, and its surface quite dull, the serial punctuation of the elytra coarser and 
the interstitial punctuation more obsolete, and the yellow mark smaller. 
45. Tenebroides bimaculatus, sp. n. (Tab. XIII. fig. 22.) 
Parvus, piceus, supra eneus, nitidus, antennis, pedibus elytrorumque maculis duabus parvis, testaceis. 
Long. 33 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
This insect also appears to be very closely allied to 7. fenestratus, though it is only 
half the size, and differs slightly in nearly all its details from any specimen I have seen 
of that species. The joints of the club of the antenne are somewhat more elongate and 
less broad than they are in 7. fenestratus. The head and thorax are very shining, the 
former smaller than in 7. fenestratus, and rather more coarsely and sparingly punctured, 
the latter very short and more strongly rounded at the sides in front. ‘The serial 
punctuation of the elytra is well developed, but the interstitial punctuation is scarcely 
visible; the spot on each wing-case is placed in the same position as it is in 7’. fenes- 
tratus, but is small, and does not extend halfway to the external margin. One specimen. 
46. Tenebroides sennevillei. 
Tenebroides sennevillei, Léveillé, Ann. Soc. Ent. Fr. 1888, p. 425°. 
Hab. Mexico!; Gvuatemata, Yzabal (Sallé), Chacoj, Torola, Zapote, Pantaleon 
(Champion) ; Nicaragua, Chontales (Janson); Panama, Bugaba, Tolé (Champion). 
This is apparently the least rare of the smaller species of Tenebroides, and varies very 
little. |
