TROGODERMA. 647 
1. Trogoderma filipes, sp. n. 
Oblongo-ovale, parum convexum, nigrum, griseo-vestitum ; elytris fasciis duabus, transversis, irregularibus, sat 
conspicuis albidis. 
Long. 3 millim. 
Hab. Mexico, Guanajuato, Puebla (Sallé); Centrat Averica (coll. Sharp). 
I have seen only the male of this species, which is evidently allied to the North- © 
American T. sternale, Jayne. Antenne black, except the small second and third 
joints, which are obscurely yellow; third joint extremely minute ; joints 5-10 trans- 
verse, the eleventh acuminate, twice as long as the tenth. Eyes round, convex. 
Thorax strongly transverse, but little convex, the sides appearing somewhat flattened 
out, black, very finely punctate, with much white pubescence at the sides. Elytra 
very finely punctate, clothed with fine dark hair, with a very ill-defined broad marking 
of scanty white pubescence somewhat in front of the middle, and a narrower and even 
more obscure one before the apex. 
I have long had a specimen of this species in my collection, and there are four others 
obtained from the late M. Sallé’s Mexican collection. 
2. Trogoderma celatum, sp. n. (Tab. XIX. fig. 14, 9 antenna.) 
Oblongo-ovale, sat convexum, pube variegata dense vestitum, nigrum; elytris ex parte parum discrete rufo- 
coloratis, signaturis albo-pubescentibus discoidalem aream quasi rhomboidalem includentibus. 
Long. 3-4 millim. . 
Hab. Mexico, Guanajuato (Sallé). 
Similar to 7. filipes, but with the lateral parts of the thorax not spread out, and 
the antenne of the male much shorter. The surface is very finely punctate, and bears 
much variegate pubescence—white, pale tawny, and black; the white marks do not 
form spots, but two angulate bands in front of the middle touch at a point on each 
side of the suture, so as to enclose a small space of dark colour, somewhat rhomboidal 
in form. The thorax is covered with pubescence, variegate all across, so that only a 
comparatively small space in front of the scutellum remains black. The elytra are 
stained with red (independent of pubescence) to a variable extent. The legs are obscure 
red. The male antenne are short and very broad; the third and fourth joints minute, 
fifth also very small, but slightly larger than the fourth (these three joints are not very 
definitely separated); sixth strongly transverse ; seventh to eleventh forming a long 
broad club of very short joints, the eleventh not being elongate, though nearly as long 
as the two preceding together. 
Described from four specimens in a very bad state of preservation, so that I have 
taken the description of the colour from the female; but I believe all are really one 
species. It is apparently allied to 7. simulaus, Casey. ‘The eyes are round and 
prominent.
