490 -COLYDIIDA. | 
4. Bothrideres solitarius, sp.n. 
- Haud depressus, ferrugineus, capite prothoraceque fuscescentibus, setosus; prothorace subquadrato, dorso 
impresso medio ante basin profunde foveolato, basi bidenticulata; elytris setis erectis armatis. 
Long. 33 millim. . 
Hab. GuatEMaLa, Cerro Zunil (Champion). — 
Head rather closely and coarsely punctate, setose; club of antenna large. Thorax 
quadrate, coarsely punctate, setigerous, with a large depression on the middle, and 
behind it a very definite round fovea; on each side of this there is, as it were, a 
very slight elevation directed backwards, so that in profile the base appears bidenticu- 
late; the hind angles are rectangular, minutely prominent. Elytra moderately elongate, 
subcostate ; the alternate interstices setose, the outer one armed with distinctly erect 
sete. Legs rather short. 
Only one example was received of this species; it is, perhaps, nearest to B. parvulus. 
5. Bothrideres subvittatus, sp. n. 
Angustus, haud depressus, parce setosus, nigricans; antennis rufis; pedibus elytrisque rufo-obscuris, his ad 
suturam spe nigricantibus; prothorace dorso bifoveolato. 
Long. 23-3} millim. . 
Hab. GUATEMALA, near the city, Zapote (Champion). 
Antenne red; club large. Thorax rather longer than broad, a little narrowed 
behind, convex; angles obtuse, coarsely punctate, with two large fovee—one in front 
of, the other behind, the middle. Llytra finely seriately punctate; the sutural inter- 
stice with fine distant punctures, the first interstice outside this polished, without 
punctures; the second and fourth interstices punctate, the third and fifth impunctate. 
The polished interstice becomes broader and deeper at the apex, and is set on its deepest 
apical part with some transverse impressions or coarse rugosities. 
This species should perhaps be separated to form a distinct genus, as the front coxe 
are only half as widely separated as they are in the normal Bothrideres. 
TAPHRIDERES, gen. nov. 
Coxe anteriores haud depress, parum distantes. 
The insect for which I establish this genus has the appearance and most of the 
characters of the narrow species of Bothrideres, but the front coxe are still more 
approximate in Taphrideres; moreover, the front coxe are not so very deeply inserted 
as they are in Bothrideres, and thus the prosternal process appears somewhat depressed 
between them. So far as the prosternal process is concerned, Taphrideres therefore 
connects Bothrideres with the more ordinary forms, in this respect, of Colydiide.
