442 HETEROMERA. 
1. Polyidus meridionalis. (Tab. XX. figg. 18, 13¢, 3; 18a, labium; 13 8, 
maxilla and maxillary palpus.) 
Brownish-piceous, slightly shining, thickly clothed with long pubescence. Head closely and rather coarsely 
punctured; antenne ferruginous or fusco-ferruginous, the third and fourth joints equal in length ; pro- 
thorax convex, the basal fovew scarcely indicated, the hind angles subrectangular, the disc unimpressed, 
the surface somewhat coarsely, closely, and uniformly punctured; scutellum closely and finely punctured ; 
elytra with rows of coarse punctures placed upon shallow striz, the strie becoming deeper towards the 
sides and apex, the interstices broad and almost flat on the disc and feebly convex laterally and towards 
the apex; beneath sparsely and rather coarsely punctured, the metasternum and side-pieces very coarsely 
so, the flanks of the prothorax almost smooth ; legs rather slender, fusco-ferruginous, the tibie similar in 
both sexes. 
g. The lateral lobes of the last ventral segment slightly curved, the apices blunt and clothed with long fine 
hairs ; the central sheath narrow and acuminate. (Fig. 13.) 
Length 74-8} millim. ; breadth 33-4 millim. (¢ 9.) 
Hab. Muxtco, Tapachula in Chiapas (Hége); Guaremata, El Reposo 800 feet 
(Champion). 
Four examples from Guatemala and one from Mexico, all captured on the lower 
part of the Pacific slope and at localities not very far distant from each other. 
MENES. 
Last joint of the labial palpi broad ovate, broadly truncate at the apex; last joint of the maxillary palpi 
broadly triangular, its apical side the longest; mandibles very feebly bifid at the apex; antenne stout, 
rather short, the joints widening a little towards their apex in both sexes—3 distinctly longer than 4, 
6-11 about equal in length; head broad; eyes small, very widely separated ; prothorax very broad and 
short, about twice as broad as long, much rounded at the sides, transversely convex, unimpressed, the base 
very feebly bisinuate, the hind angles very obtuse; scutellum strongly transverse, triangular; elytra 
short, broad, the sides almost forming (when viewed from above) a continuous outline with the equally 
broad prothorax; legs very short and stout, thickly pubescent; anterior and intermediate tarsi with the 
third and fourth joints, and the posterior tarsi with the penultimate joint, broadly lobed beneath, the first 
joint of the latter short ; claws pectinate ; prosternum abruptly declivous behind ; metasternum very short ; 
intercoxal process broad ; body short ovate, broad, convex, thickly pubescent, winged. 
This very distinct genus contains two species from Mexico. The very short ovate, 
convex shape and short legs give Menes quite a different facies from any of the previously 
described members of this family. In its broad intercoxal process Menes approaches 
the ‘ Lystronychides’; but it is clearly more nearly allied to Polyidus, Hymenorus, &c. 
The sexes are scarcely distinguishable by external characters. The wings are small and 
apparently not adapted for flying. 
1. Menes meridanus. (Tab. XX. fig. 12.) 
Brownish-black, slightly shining, somewhat thickly pubescent. Head closely and rather coarsely punctured ; 
prothorax closely punctured, the punctures fine on the disc and becoming coarser towards the sides ; 
scutellum closely and finely punctured; elytra deeply striate, the striz with coarse, oblong, rather 
distantly placed impressions, the interstices feebly convex, flatter on the basal half of the disc, and finely 
and thickly punctured ; beneath more shining, closely and coarsely punctured, the metasternum with 
exceedingly coarse impressions ; legs and antenn ferruginous or fusco-ferruginous. 
Length 64-7 millim.; breadth 33-33 millim.
