GLYPHONYX. 543 



presternum and propleurse have a few fine widely scattered punctures. The feebly 

 refiexed margins of the front meet at an obtuse angle in the centre. The insect varies 

 from 3-4^ millim. in length. 



The specimens in the Salle collection are labelled Agriotes infimus, Deyr. (=mewicanus, 

 Chevr.), and one of those in the Janson collection (from that of Candeze) is ticketed 

 G.flavipes, Cand. We are indebted to Dr. Candeze for the loan of the type.

Fifteen specimens of this species are before me, eleven of which are from Mexico. 

 This species, which, as Dr. Horn remarks, has very much the facies of a Horistonotus 

 or Esthesopus, is of a testaceous or rufo-testaceous colour, with the suture of the elytra 

 sometimes infuscate. The front is triangular and sharply margined. The third joint 

 of the antennae is slightly longer than the second. The thorax is as long as broad, with 

 the lateral carina extending forwards to about the middle, and the inferior marginal 

 carina sinuous behind. The elytra are more or less distinctly carinate near the sides 

 at the apex, the carinas arising from the seventh or eighth interstices and sinuously 

 converging posteriorly, the apices appearing narrow and separately rounded. The long 

 prosternal process is compressed behind the coxaa, appearing Y-shaped as viewed from 

 beneath, the triangular intercoxal portion being margined, and the posterior portion 

 reduced to a thin lamina. The hind coxal plates are moderately dilated in their 

 inner third. 



13. Glyphonyx laticollis. (Tab. XXIII. fig. 29.) 



Moderately elongate, subfusiform, shining ; brownish-testaceous, the legs testaceous, somewhat thickly pubes- 

 cent. Head finely and rather sparsely punctured, the punctuation becoming denser behind • front broad, 

 the margins meeting at an obtuse angle in the centre ; antennas about reaching the hind angles of the 

 prothorax, joint 3 shorter than 2. Prothorax much broader than long, rapidly narrowing from about the 

 apical third, almost parallel behind ; the hind angles acutely produced, not divergent; the lateral carina 

 sharp and extending to near the apex, the inferior marginal carina widely separated from it anteriorly 

 and strongly sinuous behind ; the surface sparsely punctate, the punctuation becoming closer and coarser 

 towards the apex, and very fine and diffuse towards the base ; the basal plicae long and well-defined. Elytra 

 three times the length of the prothorax, and narrower than it, a little rounded at the sides, narrowing 

 from the base, somewhat, pointed behind ; punctate-striate, the interstices flat and sparsely punctured. 

 Presternum and propleurse with a few fine widely scattered punctures; metasternum and abdomen 

 closely, finely punctate, the sides of the metasternum with coarse punctures ; prosternal process Y-shaped, 

 the triangular intercoxal portion margined. Posterior coxal plates feebly dilated in their inner third.
