TENEBROIDES. 433 
This is a very different species from any other Tenebrotdes found in our region, and 
may probably be allied to 7. antennalis, Reitter, from Colombia. We have received 
eight examples of it; the one from Chontales has the striation of the elytra finer than 
the others. 
41. Tenebroides explanatus. (Tab. XIII. fig. 20.) 
Tenebrioides explanatus, Reitter, Verh. Ver. Briinn, xiii., Abhandl. p. 73°. 
Hab. Panama, Volcan de Chiriqui (Champion).—Sovutu America, Colombia ?. 
Also a very distinct species, with the front of the head elongate, and a large club 
to the antenne. The thorax is very strongly transverse, but considerably narrower 
than the very broad elytra. 
Group 4.—Insects of very small size, with variegated or metallic surface. 
(Species 42-52.) 
42. Tenebroides gracilipes, sp.n. (Tab. XIII. fig. 21.) 
Parvus, parum elongatus, depressus, testaceus, subopacus, subtiliter punctatus, elytris obsolete striatis. 
Long. 3 millim. 
Hab. Panama, Bugaba, Tolé (Champion). 
Antenne quite pale, with large club. Head flat, finely punctate. Thorax very 
strongly transverse, slightly narrowed behind ; front angles a little produced, rather 
broad; hind angles slightly obtuse; basal and lateral margins fine, the latter uninter- 
rupted; surface dull, rather finely punctate. Elytra with fine, indistinct strize and 
very fine interstitial punctuation. Legs very slender. 
The two examples received of this species are no doubt male and female, as one of 
them has a large transverse depression on the terminal ventral plate and the front margin 
of the depression bears a few hairs; this may perhaps be the female ; no trace of this 
depression exists in the other specimen. 
T. gracilipes is not like any other species of the genus; its small size and pallid 
colour give it some resemblance to the Cryptophagide. 
43. Tenebroides fenestratus. 
Tenebroides fenestratus, Léveillé, Ann. Soc. Ent. Fr. 1888, p. 425°. 
Hab. Mexico!, Juquila (Sallé), Jalapa, Esperanza (f6dge); GuaTEMALA, Purula 
(Champion). 
Herr Hoge procured a small series of eight examples of this species at Jalapa; they 
exhibit some variety in size, colour, and sculpture, though not in an extreme degree. 
The two specimens found by Mr. Champion in Guatemala are somewhat different, 
being of rather larger size and darker colour, with the pallid mark on the elytra less
