HYMENORUS. 429 
almost flat and closely, shallowly, and confusedly punctured; beneath closely punctured; legs slender, 
ferruginous. 
Length 8 millim.; breadth 22 millim. 
Hab. Mexico, Cordova (Sallé). 
One specimen only, apparently of the female sex. Duller and more depressed than 
H. sordidus; the thorax less convex and distinctly canaliculate; the elytra relatively 
longer, with shallower strize and more finely punctured interstices; the eyes widely 
separated, &c. 
9. Hymenorus flohri. (Tab. XIX. fig. 23.) 
Moderately elongate, rather depressed, dull brownish-piceous, the elytra slightly shining, thickly pubescent. 
Head very closely and finely punctured; eyes rather small, not very widely separated in the male, more 
distant in the female; antenne rather short in both sexes, moderately stout, ferruginous ; prothorax 
strongly transverse, rather depressed, the sides a little rounded and converging from the base, the hind 
angles subrectangular, the disc canaliculate at the extreme base, the basal fove obsolete, the surface 
finely and very densely punctured; scutellum closely punctured; elytra moderately long, rather wider 
than the prothorax, subparallel in their basal half, finely and deeply punctate-striate, the interstices very 
feebly convex and finely and thickly punctured; legs slender, moderately long, ferruginous or fusco- 
ferruginous ; anterior and intermediate tarsi with the third and fourth joints, and the posterior tarsi with 
the penultimate joint, very feebly lobed beneath. 
Length 73-8 millim.; breadth 23-34 millim. (3 9.)

Two examples. 
10. Hymenorus laticollis. 
Moderately elongate, rather depressed, brownish-piceous, slightly shining, thickly pubescent. Head very closely 
and coarsely punctured; eyes (¢ ) small, widely separated; antennse ( ¢ ) moderately long, rather slender, 
ferruginous ; prothorax large and broad, transverse, the sides expanded and much rounded anteriorly and 
almost straight behind, the hind angles obtuse, the lateral margins thin and prominent, the basal foveze 
indistinct, the surface very densely and finely punctured, the disc unimpressed but with traces of a smooth 
central line; scutellum closely punctured; elytra moderately long, a little wider than the prothorax, 
subparallel in their basal half, with rows of fine oblong punctures placed upon very shallow striz, the 
interstices flat and closely, confusedly, and not very finely punctured ; legs slender, rather long, ferruginous. 
Length 7} millim.; breadth 3 millim. (¢.) 
Hab. Mexico (coll. F. Bates). 
A single male example. This insect is closely allied to H. flohri, but differs from it 
in the more coarsely punctured head, more widely separated eyes in the male, larger 
and more expanded thorax, more lightly impressed elytral stria, less finely punctured 
interstices, longer legs, and more distinctly lobed tarsi. Labelled Allecula laticollis, 
Dej., in Mr. F. Bates’s collection. 
11. Hymenorus grandicollis. 
Elongate ovate, brownish-black, opaque, thickly pubescent. Head closely and rather coarsely punctured ; 
eyes (¢) large, narrowly separated; antenne (<3) moderately long and stout, ferruginous; prothorax
