2. Pediacus similis, sp. n. 
Depressus, fusco-niger, pedibus piceis ; prothorace dense fortiterque punctato, anterius transversim impresso, 
lateribus denticulatis ; elytris opacis, dense minus subtiliter coriaceis. 
Long. 6 millim. 
Hab. GuaTeMaua, Cerro Zunil (Champion). 
We have received only two examples of this species; it appears to be excessively 
similar to P. major, but the densely, and comparatively coarsely, coriaceous sculpture of 
the elytra forms so marked a distinction that I think it better to separate the two 
forms. 
3. Pediacus confertus, sp. n. 
Depressus, fusco-niger, opacus, pube subtili depressa sparsim vestitus; prothorace densissime punctato, lateribus 
denticulatis ; pedibus rufo-obscuris. 
Long. 4-5 millim. 
Hab. Guatemata, Totonicapam 8500 to 10,500 feet, Quiché Mountains 7000 to 
9000 feet, Capetillo (Champion). 
Head densely punctured, slightly shining. Thorax strongly transverse, extremely 
densely punctured, and with a distinct depressed flavescent pubescence, the sculpture 
towards the sides assuming the form of fine granules; there is scarcely any trace of a 
smooth line down the middle, and the surface is almost unimpressed; the lateral 
denticulation is distinct, there being three acute denticles on each side, and between 
the anterior one and the second an obtuse angulation of the margin; the third, or 
posterior, denticle is placed scarcely at all in front of the basal line. ‘The elytra are 
remarkably dull, owing to a very dense coriaceous sculpture, and they have a very 
scanty, extremely depressed setosity of a yellowish, almost golden, colour. Under 
surface closely and finely punctate. 
Twelve specimens were met with at Totonicapam and Quiché under the bark of 
fir-trees. The single specimen from Capetillo belongs, I think, to the same species, 
though the setosity of the surface is rather more conspicuous. 
4. Pediacus mexicanus, sp. n. 
Depressus, fusco-ferrugineus, antennis pedibusque rufis; subnitidus, tenuissime pubescens; prothorace dense 
punctato, lateribus denticulatis. 
Long. 4-44 millim. 
Hab. Mexico, Jacale (Sallé). 
Head finely punctate, with a distinct minute angle behind the eyes. ‘Tborax with 
the disc fuscous, the margins more or less broadly ferruginous, densely and finely 
punctate, the lateral denticles distinct, the posterior one placed at the base. LElytra 
somewhat shining, minutely pubescent, the coriaceous sculpture very fine. 
We have received only two examples of this insect, and one of them has lost its leg
