TYMPANOPHORUS.—SELMA. 343 
in the Berlin collection. To it must also be assigned the North-American Eury- 
porus puncticollis, Er., and I am able to add a third species, found in our region. 
It appears strange that so careful a writer as Erichson should, after having described 
fully ? the peculiarities of the genus in the same work, have referred a second species of 
it to a genus where it was evidently misplaced. Nordmann’s sketch! of the maxillary 
palpi is deceptive, and does not accord with his (or with Erichson’s) description ; the 
terminal joint of the palpus is quite as long as the preceding joint. 
1. Tympanophorus concolor. (Tab. VIII. fig. 13.) 
Nigerrimus, nitidus, pubescentia concolore minus tenui vestitus; capite parvo densissime punctato, medio 
levigato ; prothorace ovato-circulari, crebre fortiter punctato, linea mediali impunctata; elytris crebre 
fortiter punctatis, vix longioribus quam prothorax ; abdomine nitido, parce punctato, conspicue nigro- 
pubescente. 
Long. 13 millim. 
Hab. Costa Rica, Irazu 6000 to 7000 feet (Rogers). 
This species is closely allied to 7. puncticollis, but is readily distinguished by its 
intense black colour, it being clothed with concolorous pubescence instead of an ashy 
one; the punctuation of the head is denser and coarser. ‘The male has on the middle 
of the lower aspect of the penultimate segment of the hind body an elevated space open 
behind so as to appear deeply bifid. 
I have examined four specimens of this species as well as the fragments of a fifth 
individual. 
2. Tympanophorus puncticollis. 
Euryporus puncticollis, Er. Gen. et Spec. Staph. p. 554°; Solsky, Hor. Soc. Ent. Ross. v. p. 123°; 
Horn, Tr. Am. Ent. Soe. vii. p. 149°. 
Hab. Norra America !3,—MExtco ?. 
The only indication of this insect belonging to the fauna of our region is Solsky’s 
bare record of its name as a Mexican insect. It is, I believe, very rare in the United 
States, and [am much indebted to Dr. Horn for having supplied me with the individual 
that has enabled me to point out for the first time the genus to which it truly belongs.

The genus at present comprises only one species.
