590 MR. M. JACOEY ON PHYTOPHAGOUS COLEOPTERA. [NoV. 16, 



a black transverse sinuate fascia at the apex, surrounding a light 

 flavous apical spot. 



Lenifth 5 lines. 



Head distinctly punctured in front of the eyes, black ; lower part 

 of the face deeply excavated, that portion, as well as the anterior 

 margin of the clypeus and labrum, flavous ; two testaceous spots are 

 placed near the ujiper part of the eyes. Antennae rather long, ex- 

 tending further than the base of the thorax, fulvous, the first four 

 joints black above. Thorax impunctate, of usual shape. Elytra 

 moderately deeply and closely punctured, coloured like the thorax ; 

 the apex of each elytron occupied by a black narrow band in the shape 

 of a ring, the upper portion of which is widened towards the lateral 

 margin ; the space within this ring is of a light testaceous or yellowish 

 colour, as well as a convex narrow band above the black marking ; the 

 elytra may also be described as light flavous at their last third, in- 

 terrupted by a black ring near the apex ; a short lateral streak of 

 flavous extends also from the shoulders downwards. Underside tes- 

 taceous ; sides of the breast and base of the mesothorax black ; legs 

 fulvous, tarsi and claws piceous. 



Mus. Godman and Salvin. 



7. Mastostethus suavis. Bates. 



Of this specie.'^, two specimens were collected by Mr. Buckley. 

 The elytra have four black spots each, of which the two anterior ones 

 are longitudinal and oblique, the others transverse, but isolated in 

 the specimens from Ecuador, and not connected in shape of a ring, 

 according to Mr. Bates's description of his type. 



Genus Agathomerus, Lacord. 



8. Agathomerus simplicipennis, sp. nov. 



Elongate, parallel. Flavous-testaceous ; shining, a transverse 

 hand at the vertex, labrum, antennae, part of the anterior femora, 

 and the tibiae and tarsi black. 



Length 5 lines. 



Head deeply punctured near the eye, the rest impunctate ; flavous, 

 with a broad black band between the eyes. Antennae extending to 

 the base of the thorax, black, the first four joints shining, the rest 

 pubescent. Thorax transverse, sides nearly straight seen from above ; 

 disk with a transverse groove near the anterior and jjosterior margins, 

 the former slightly arched at each side, the latter nearly straight ; 

 surface glabrous, impunctate, fulvous, margined anteriorly and pos- 

 teriorly with testaceous. Scutellum trigonate, its apex rounded. 

 Elytra closely but rather finely punctured, the punctures much more 

 distant towards the apex, coloured like the thorax. Underside of 

 the same colour, the femora rather darker ; hinder tibiae distinctly 

 curved, covered, like the rest of the underside, with long testaceous 

 hairs.
