6. Attains malachioides, n. sp. 



(J. Elongate, narrow, shining; aeneous, the mouth-parts, the 

 anterior margin of the head to between the eyes on each side, a 

 small spot on the epistoma, the hind angles of the prothorax narrowly, 

 the coxae, trochanters, and legs (a streak along the upper edge of 

 the femora and the apices of the tibiae and tarsi excepted), and 

 sometimes the outer limb and apex of tlie elytra also, testaceous 

 or flavous; finely pubescent, with intermixed longer bristly hairs. 

 Head considerably elongated behind the eyes, including the latter 

 as wide as the prothorax, polished, excessively minutely punctulate, 

 bifoveate in front, the eyes large ; antennae long, feebly werrate, 

 joints 3 and 4 subequal in length, 5-11 more elongate. Prothorax 

 slightly broader than long, moderately rounded at the sides, polished, 

 obsoletely punctulate. Elytra long, subparallel, a little wider than 

 the prothorax; densely, very minutely punctate. Posterior tibiae 

 bowed. 



Anterior tarsi with the prolonged upper portion of joint 2 reaching 

 the apex of .3. 



Length 2} mm. 



Hab. Mexico, Cordova (Hoge). 



Two males, one of which has the outer Hmb and apex 

 of the elytra flavous. The insect is not very closely 

 allied to any of the other species enumerated in the present 

 paper. It has the head basally elongated and the elytra 

 subparallel much as in the same sex of A. nigritulus, Gorh. 

 The metalhc aeneous colour, the poUshed head, with 

 sharply defined flavous anterior margin, the rather long, 

 pohshed prothorax, the very densely sculptured elytra, 

 and the pallid legs are characteristic. 



7. Attains plagiatus. 



Anthocomns plagiatus, Gorh., Biol. Centr.-Am., Coleopt. iii, 

 2, p. 115. 



cj. Anterior tarsi with joints 1 and 2 testaceous, 2 prolonged 

 above into a stout lobe which reaches the apex of 3. 



Hab. Guatemala, Calderas, on the slope of the Volcan 

 de Fuego. 



Gorham described the female only of this species, although 

 he had specimens of both sexes before him. A. jdagiatus 

 has the facies of a Malachius, owing to its long, opaque 

 elytra, which are subparallel in the male. The head is
