234 SUPPLEMENT. 
Guiana, but our species presents no traces of the coste which Thomson mentions as 
strongly developed in S. costifer. 
Ergates corticarius, Erichson (Schomb. Reise, iii. p. 571), from British Guiana, is 
evidently a species of Strongylaspis, but is more nearly allied to S. scobinatus, the upper 
surface being “sehr fein gekornt,” and the thorax “nach vorn geschmalert.” 
MALLODONOPSIS (p. 7). 
Mallodonopsis mexicanus (p. 7). 
To the localities given, add :—-MeExtico, Orizaba (Sailé), Misantla (Hoge); GuaTEMALA, 
Cubulco (Champion); Costa Rica (Van Patten); Panama, Bugaba (Champion). | 
Mallodonopsis corrosus (p.7). (Tab. XVI. fig. 10.) 
We now give a figure of this species. 
APLAGIOGNATHUS (p. 7). 
Aplagiognathus spinosus (p. 8). 
To the locality given, add :—-MeExico, Parada (Sallé), Misantla (Hoge). 
Specimens in the Sallé collection bear MS. names by Sturm, “AMallodon armatum, 
M. foveicolle, and M. levicolle,” two forms of the male and the female being considered 
so many separate species. | 
Aplagiognathus hybostoma (p. 8). (Tab. XVI. fig. 9, 3.) 
Prionus subsulcatus, Dalman, Anal. Ent. p. 63 (1828) ? 
Agrees with Dalman’s description in many important points, such as the shortness 
and thickness of the first antennal joint (“art. primus crassus obconicus”) and the very 
thick mandibles surmounted at the base by a tubercle (“ mandib. crassissime, basi tuber- 
culo obtuso elevato armato”); but it differs in the mandibles being much shorter than 
the head, not “longitudine capitis,” and apparently also in the outline of the thorax. 
Dalman’s description has been overlooked by the compilers of the Munich catalogue, as 
well as by White and Lacordaire. 
NOTHOPLEURUS (p. 8). 
8. Nothopleurus mandibularis. 
Mallodon mandibulare (p. 10). 
Add to the synonymy :—Mallodon (Nothopleurus) dentiger (Leconte), Crotch, Check-list N. Am. 
Col. p. 82. 
To the locality given, add :—NortH America, California, Texas——Muxico, Presidio 
(Forrer).
