116 Mr. G. C. Champion's Revision of the Mexican 



Hah. Guatemala, Quiche Mts., Quezaltenango, and near 

 Capetillo. 



This species is extremely hke L. subcyaneus, differing 

 from it in the simple fifth ventral segment of the male. 

 The antennae and tarsi are equally variable in colour. 

 The seven specimens seen are cupreous or plumbeo- 

 cupreous in colour, the prothorax sometimes greenish or 

 golden. The vestiture is very compact in fresh examples. 

 The sexual characters were not described by Gorham. The 

 length varies from 3 to nearly 4 mm. 



3, Listrus suhcwpreus, n. sp. 



(J. Moderately elongate, narrow, depressed, shining; obscure 

 cupreous with the head and prothorax greenish, or wholly greenish, 

 the antennae (except the first joint at the base above) testaceous, 

 the legs piceous, with the tarsi fusco-testaceous ; finely cinereo- 

 pubescent. Head densely punctate; antermae slender, widening 

 outwards, feebly serrate, joint 10 transverse, 11 stout, ovate. Pro- 

 thorax small, strongly transverse, rounded at the sides, the hind 

 angles subrectangular ; closely, minutely punctate. Elytra wider 

 than the prothorax, subparallel in their basal half, moderately 

 elongate ; densely, finely punctate. Fifth ventral segment flattened 

 and densely punctate in the middle at the apex, the latter truncate. 

 Anterior and intermediate tibiae bowed towards the apex, sinuate 

 within, toothed at the iimer apical angle. 



$. Broader; antennae with the four or five outer joints, and the 

 basal one above, black, 6-10 transverse. 



Length 2^-2^ mm. ((^$.) 



Hah. Guatemala, Guatemala city, Duehas, Capetillo 

 {Champion). 



Two males and three females, found mixed with the 

 series named L. canescens by Gorham. Smaller and much 

 less elongate than L. cupreonitens and L. suhcyaneus, the 

 antennae and legs shorter, the fifth ventral segment of the 

 male simply flattened in the middle behind. 



4. Listrus flavicornis, n. sp. 



(J. Elongate, the head and prothorax dull, the elytra moderately 

 shining; aeneous, the antennae (the black basal joint excepted), 

 tarsi, and apices of the tibiae, testaceous; clothed with rather 

 long, decumbent, pallid hairs, those on the elytra rather coarse, the 

 curled marginal cilia of the latter long and conspicuous. Head bi- 

 impressed in front, alutaceous, very finely, rather sparsely punctate ;
