HYMENORUWS. 437 
densely and not very finely punctured; scutellum closely punctured ; elytra moderately long, the width of 
or very little wider than the prothorax at the base, with rows of moderately coarse punctures placed upon 
shallow striw, the punctures closely placed, the interstices almost flat or very feebly convex and finely and 
rather closely punctured ; legs short and rather slender, ferruginous. 
Length 53-63 millim.; breadth 2-2! millim. (3 Q.) 
Hab. Mexico, Jalapa (Hoge); Guatemata, Ostuncalco 7500 feet, Calderas, slopes of 
the Volcan de Fuego above Capetillo (Champion). 
_ Many examples. This insect is not uncommon in the Los Altos region of Guatemala ; 
it is distinguished from the preceding species by its small eyes, slightly shining surface, 
and by the sides of the thorax converging from the base. Two examples only have 
been received from Mexico. As in several of the allied species the sexes are scarcely 
distinguishable by external characters. 
29. Hymenorus punctatissimus. 
Hymenorus punctatissimus, Lec. New Sp. Col. p. 188 (1866) '. 
Hab. Nortu America, Arizona !—Mextco, Northern Sonora (Morrison). 
From the late Mr. Morrison we have received three perfectly distinct species under 
the above name. One of these, represented by two male examples, is undoubtedly 
H. punctatissimus; the other two are here described under the names of Z. ruficollis 
and fH. deplanatus. ‘The two examples mentioned have the thorax exceedingly densely 
and finely punctured; and the elytra with very shallow and very finely punctured strie, 
the interstices very closely and finely punctured, the punctures very little coarser than 
those of the striz. 
30. Hymenorus maritimus. 
Oblong, piceous with a slight bronzy tinge, the prothorax sometimes very narrowly and indistinctly ferruginous 
at the sides and base, the head ferruginous in front, slightly shining, thickly clothed with long ashy 
pubescence. Head somewhat coarsely and closely punctured ; eyes rather small, somewhat widely sepa- 
rated; antenne short and stout in both sexes, the joints short and thickened towards their apex, brownish- 
black, the two basal joints ferruginous; prothorax broader than long, the sides rounded and converging 
anteriorly and almost straight behind, the base feebly bisinuate, the hind angles rectangular, the disc obso- 
letely canaliculate behind, the surface densely and not very finely punctured ; scutellum closely punctured ; 
elytra rather short, about as wide as the prothorax, subparallel in their basal half, shallowly and rather 
finely punctate-striate, the interstices finely and closely punctured ; legs short, ferruginous, the tibic some- 
times a little darker; apical joint of the maxillary palpi brownish-black. 
Length 44-44 millim.; breadth 1? millim. (¢ @.) 
Hab. Guatemaua, Champerico (Champion). 
Four examples of this distinct insect were captured by myself on the Pacific coast at 
Champerico. HH. maritimus is one of the smallest of the Central-American species, and 
may be recognized by its narrow and somewhat parallel shape, rather short elytra, and 
slight bronzy tint.
