252 | SUPPLEMENT. 
A single specimen of a small insignificant-looking species, distinguishable by the 
sculpture of the thorax, which is unlike that of any other species in the same sex. 
CACOPHRISSUS (p. 26; to follow the genus Hypermallus). 
Gen. Stromatio sat affinis. Corpus fere cylindricum, grosse incumbenti-pubescens et passim dense setosum. 
Caput antice verticale, tuberibus antenniferis rotundatis parum elevatis. Palpi breves, subequales, articulo 
terminali sat anguste triangulari. Antenne, ¢ corpore dimidio longiores, 2 corpore parum breviores ; 
usque ad apicem infra longe ciliate ; scapo quam art. 3% paullo breviori, art. 4° quam 3°* multo breviori, 
4°-11™ elongatis, singulis quam 3” longioribus, depressis, supra obtuse carinatis. Thorax cylindrico- 
ovatus, ¢ 9 similariter grosse sparsim punctatus. Elytra apice obtuse rotundata. Prosternum inter . 
coxas angustissimum. Acetabula antica extus perparum angulata; intermedia fere clausa. Femora 
gradatim incrassata, ¢ corporis apicem attingentia. 
One of the numerous feebly-characterized forms, of which there are many still unde- 
scribed in collections, allied to Hesperophanes and Stromatium, and which cannot, 
in the present state of our knowledge, be referred to any of the published genera. 
In many respects, and particularly in the form of the head, Cacophrissus seems to be 
allied to Anoplium, Haldemann, but in that genus (incorporated by Leconte with 
Elaphidion) the thorax has the sexual difference of sculpture characteristic of the 
Elaphidion group. Cacophrissus has much in common also with Perilasius, but it 
differs in the short subequal palpi (Perilasius having much elongated maxillary palpi), 
in the grooved antenne, &c. The antenne are compressed and slightly dilated, not 
sideways, but above and beneath, and the middle of the broadened upper surface is 
faintly carinated or roof-shaped, this being more visible in the male than in the female, 
and on the third to the sixth joints. 
1. Cacophrissus pauper. (Tab. VIII. fig. 8.) 
Piceo- vel castaneo-fuscus, ochraceo-fulvo pubescens et setosus; thorace sat elongato, convexo, antice et postice 
eequaliter et modice angustato, grosse et sparsim punctato; elytris sparsim et minus grosse punctatis. 
Long. 54-8 lin. ¢ 9. 
Hab. Mexico, Presidio (Forrer). 
TRICHOPHORUS (p. 26). 
Trichophorus decipiens (p. 26). (Tab. XVII. fig. 7.) 
We now figure this species. 
3. Trichophorus jansoni. 
Fulvo-rufus, nitidus, erecte hirsutus, tomento cinereo-albo variegatus ; thorace plagis elongatis tribus nitidis, 
interstitiis ¢ minute, ? alveolato-punctatis ; elytris sparsius punctulatis, apice anguste sinuato-truncatis 
angulo suturali breviter, exteriori longe, spinosis ; scutello, episternis ventrisque maculis lateralibus dense 
cinereo-tomentosis ; antennis (¢ @ ) articulis 3°-7™ breviter spinosis; femoribus apice muticis ; anten- 
narum articulis 3°-6™ inconspicue unicarinatis. 
Long. 8-9 lin. ¢ 9.
