440 HETEROMERA. 
its stouter antenne, dull and much more densely punctured thorax, shorter elytra, and 
more closely and more finely punctured interstices. In both species the elytra are very 
distinctly wider than the prothorax at the base. The comparatively small and narrow 
thorax will distinguish H. pallidus from the other species with small eyes in both 
sexes. 
86. Hymenorus villosus. (Tab. XX. fig. 10, 2.) 
Oblong ovate, rather convex, light reddish-brown, the head and elytra shining, the prothorax duller, thickly. 
clothed with long erect fulvous hairs. Head closely and coarsely punctured; eyes ( Q ) rather small, 
widely separated ; antenne stout, rather short, ferruginous ; prothorax convex, transverse, the sides very 
gradually converging from the base and rounded in front, the hind angles subrectangular, the base very 
feebly bisinuate, the surface unimpressed and densely and rugosely punctured, the punctures here and 
there longitudinally confluent ; scutellum closely and finely punctured ; elytra rather long, distinctly wider 
than the prothorax at the base, coarsely and deeply punctate-striate, the interstices convex and sparsely 
and coarsely punctured; beneath sparsely and coarsely punctured; legs rather stout, ferruginous. 
Length 7 millim.; breadth 3 millim. ( 2.) 
Hab. Mexico, Cuernavaca in Morelos (Hdége). 
One example. This species is at once distinguished from all others of the genus by 
its densely villose surface ; it has the base of the thorax very feebly bisinuate. 
87. Hymenorus parvicollis. | 
Elongate, rather narrow and depressed, piceous-brown, slightly shining, somewhat thickly clothed with short 
pubescence. Head (including the vertex) closely and rather coarsely punctured ; eyes (¢) small, widely 
separated ; antennx ( ) rather long and slender, fusco-ferruginous ; prothorax small and narrow, strongly 
transverse, the sides almost straight behind and a little narrowed and rounded in front, the hind angles 
rather obtuse, the disc shallowly transversely impressed behind, the base feebly bisinuate, the surface 
densely and rather coarsely punctured ; scutellum closely punctured ; elytra long, considerably wider than 
the prothorax at the base, subparallel in their basal half, rather coarsely (but shallowly) punctate-striate, 
the interstices flat and somewhat closely punctured; beneath very sparsely and finely punctured, the sides 
of the metasternum more coarsely so; legs slender, ferruginous, the basal joint of the hind tarsi the length 
of the following joints united, the tibie straight. 
Length 42 millim.; breadth 13 milim. (¢.) 
Hab. Mexico, Ventanas in Durango 2000 feet (Hoge). 
One immature male example. This small species is not very closely allied to any 
other noticed here ; it somewhat approaches LH. guatemalensis and IT. pallidus. 
88. Hymenorus deplanatus. (Tab. XX. fig. 11, ¢.) 
Elongate, narrow, depressed, brownish-piccous, dull, thickly clothed with short pubescence. Head finely and 
closely punctured, the intraocular space and the vertex sparsely and more coarsely so; eyes small and 
widely separated in both sexes; antennz rather short, not longer in the male, the joints very little 
widened towards their apex, ferruginous; prothorax transverse, the sides parallel behind and rounded and 
slightly narrowed in front, the hind angles subrectangular, the basal fovez indistinctly indicated, the base 
feebly bisinuate, the surface finely and very densely punctured ; scutellum closely punctured ; elytra long, 
a little wider than the prothorax at the base, the sides almost straight from the base to the middle, finely 
and closely punctate-striate, the interstices flat and finely and closely punctured; beneath sparsely and 
tinely punctured, the metasternum at the sides much more coarsely so and in the middle (in both sexes)
