436 HETEROMERA. 
so densely punctured; the elytra relatively shorter, the strie more deeply impressed, the interstices 
closely punctured ; the legs stouter and much shorter; the rest much as in H. colonoides. 
Length 43 millim.; breadth 2 millim. (¢.) 
Hab. Mexico, Iguala in Guerrero (/6ge). 
Though we have only a single example of this insect there can be no doubt of its 
specific distinctness. 
26. Hymenorus torridus. 
Nearly allied to H. colonoides, and differing as follows:—Rather more convex; the eyes much larger and much 
more approximate than in the male of H. colonoides; the antenns much longer, with the joints more 
elongate; the prothorax similarly shaped and sculptured, the base very strongly bisinuate; the elytra 
more coarsely and deeply punctate-striate, the interstices closely and not so finely punctured; the first 
joint of the hind tarsi more elongate, longer than the following joints united. 
Length 5% millim.; breadth 23 millim. 
Hab. Muxico, Acapulco (Hége). 
One example, apparently a female. 
27. Hymenorus angustatus. 
Oblong ovate, rather narrow, brownish-piceous, subopaque, thickly clothed with short pubescence. Head 
closely and rather coarsely punctured, the anterior half and the oral organs ferruginous; eyes moderately 
large, equally and somewhat widely separated in both sexes; antennz rather stout, the joints considerably 
thickened towards their apex and moderately long, piceo-ferruginous, the two basal joints lighter; pro- 
thorax transverse, rather convex, the sides much rounded though parallel towards the base, the basal 
fovesw indistinctly indicated, the hind angles rectangular, the base strongly bisinuate, the surface very 
densely and finely punctured; scutellum closely punctured; elytra rather long, subparallel in their basal 
half, the width of the prothorax at the base, finely and lightly punctate-striate, the punctures closely 
placed, the interstices flat and very closely and finely punctured; legs short, ferruginous, the tibiz a little 
darker, the first joint of the hind tarsi the length of the following joints united. 
Length 51-6 millim.; breadth 2-23 millim. (¢ 9.) 
Hab. Guatemana, San Gerénimo (Champion). 
Four examples. Narrower, duller, and more parallel than H. emmenastoides; the 
eyes larger and more narrowly separated in both sexes; the sides of the thorax 
straighter behind, the surface still more densely and more finely punctured ; the elytral 
strie more lightly impressed and more finely punctured. From Z. colonoides, to which 
it is much more closely allied, it may be distinguished by its longer and more parallel 
elytra, and longer antenne and legs; the head and eyes are formed much as in 
H. colonoides, but the latter are more widely separated. 
28. Hymenorus emmenastoides. 
Oblong ovate, brownish-piceous, slightly shining, thickly clothed with short pubescence. Head closely and 
somewhat coarsely punctured, the vertex more coarsely so, the anterior half and the oral organs ferru- 
ginous ; eyes small and widely and equally separated in both sexes; antenne short in both sexes, rather 
slender, ferruginous ; prothorax transverse, rather convex, the sides rounded and converging from the base, 
the hind angles subrectangular, the base strongly bisinuate, the basal fovesx feebly indicated, the surface
