SUPPLEMENT. 
During the course of publication of the preceding pages of this volume the numerous 
Mexican and Central-American Barids belonging to the U.S. National Museum at 
Washington have been submitted to me for examination, most of these, fortunately, 
having been received in time to be included in their proper place. Mr. H. F. 
Wickham, too, has forwarded the material in this group obtained by him in Mexico 
during the past year, allowing us to retain such forms as were required. His con- 
signment has added a considerable number of species and three genera (Orthoris, 
Leptoschenus *, and a new one related to Centrinites) to our long list of Baridsf. Of 
the ten species of this group found by Mr. H. H. Smith in the Antillean islands of 
St. Vincent and Grenada, three have already been incidentally noticed (anted, pp. 202, 
274, 379); the rest of them are noted in the text or described in footnotes in this 
Supplement. 
ZYGOPINA. 
CYLINDROCOPTURUS (p. 35). 
Cylindrocopturus scaphiformis (p. 41). 
To the Mexican localities given, add :—Gonzales (Wickham). 
COPTURUS (p. 69). 
1(a). Copturus fausti. (Tab. XXIII. figg. 7, 74, 3.) 
Copturus (Macrocopturus) faustt, Heller, Abhandl. Mus. Dresden, no. 11, p. 24°. 
Hab. Costa Rica (Biolley, ex coll. Solari).—Prru !, Chamicuros (Mus. Brit.). 
Signor Solari has sent us a specimen (¢) of this species labelled as from Costa 
Rica. It is a large, robust form allied to C. martw, with the upper surface shining 
and marked with numerous, sharply defined, albo-squamose spots—five or six on the 
prothorax and about sixteen on the elytra (including two common larger patches on 
the suture); the elytra closely seriato-foveolate, and mucronate at the apex; the under 
surface densely albo-squamose ; the first ventral segment broadly depressed down the 
middle in the male. 
-* Hitherto recorded as doubtfully Mexican (¢f. antea, p. 329). 
+ It may be noted here that Oligopus pellitus, Kirsch (Deutsche ent. Zeitschr. 1875, p. 279), from Peru, 
described as a Cossonid, the type of which I have recently examined, isa tiue Barid, with an exposed 
pygidium, allied to Pithecomus, Pase., and Glyptobaris, Casey.
