AGATHOMERUS. 25 



To be distinguished from A. rufus by the black underside, femora, and the scutellum. 

 The knees, tibiae, and tarsi are rufous ; there is also a short black spot at the middle of 

 the head ; in other respects this species resembles the preceding.

Agathomerus rubrinotatus, Clark, Cat. Phys. App. p. 83. 

 Hab. Mexico. 



5. Agathomerus sallaei. 



Agathomerus sallei, Baly, Trans. Ent. Soc. ser. v. p. 153. 

 Hab. Mexico, San Andres Tuxtla (SalU). 



6. Agathomerus atripennis. 



Elongate, parallel ; testaceous below ; head and thorax rufous, the former with one, the latter with two black 

 spots ; elytra deeply and closely punctured, pubescent, black, the extreme lateral margin and the apex 

 flavous. 



Length 4 lines. 



Head coarsely punctured at the sides, more sparingly at the middle, rufous, with a large central irregular-shaped 

 spot ; antenna? entirely black, the first four joints shining, the rest closely pubescent and opaque ; thorax 

 convex, about one-half broader than long ; surface glabrous, shining, with a few but distinct punctures, 

 rufous, the disk with two elongate black spots ; scutellum rufous ; elytra parallel, slightly depressed below the 

 base, deeply and rather closely punctured, covered with light hairs ; the interstices, especially towards the 

 suture, irregularly transversely wrinkled ; the entire surface black and shining, the extreme lateral margin 

 and the apex of each elytron light yellow; the breast and legs rufous; tibiae and the abdomen testa- 

 ceous ; tarsi black. 



Hab. Mexico, Oaxaca {Salle). 



7. Agathomerus aflinis. 



Rufous below ; lower part of the face and the antennae testaceous ; head black ; thorax obscure testaceous, with 

 two black spots ; elytra coarsely but distantly punctured, black, the extreme lateral margin and the apex 

 broadly flavous. 



Length 3f lines. 



Head punctured at the sides and very sparingly across the middle, the rest smooth, black, shining ; lower part 

 of face testaceous, mandibulse black ; antennae entirely obscure testaceous ; thorax convex, nearly twice as 

 broad as long, the posterior angles not produced ; surface entirely impunctate, obscure testaceous, with a 

 large transverse black patch at either side ; scutellum flavous, the base piceous ; elytra parallel, the disk 

 flattened and distinctly depressed below the base ; surface with coarse but not closely approached punc-' 

 tures, black, the extreme margin widened at the apex into a triangular broad space, flavous ; underside 

 and legs as in the preceding species. 



Hab. Mexico, Playa Vicente (SalU). 



Although closely allied to A. atripennis, it is impossible to consider the present insect 

 a variety of that species ; the colour of the head and of the antenna?, and especially 

 the much less close punctuation of the elytra, separate it ; the thorax is also somewhat 

 differently shaped and without punctuation ; the tarsi, in the only specimen before me, 

 are unfortunately wanting.
