ANEFLUS, Zee. 



The outer antenna] joints are distinctly carinate on their flat sides 

 this sentence gives the basis on which the genus was erected. On tins 

 point some remarks will appear in the course of this article. 

 The species of Aneflus are thus distinguished: 



Outer joints of antennae more or less distinctly carinated 2 



Outer joints not distinctly carinated volitans, Lee. 



2 — Third joint of antennae with a very long spine tenuis, Lee. 



Antennal spines of moderate size 3 



3 — Elytra simply emarginate at tip linearis. Lee, 



Elytra spinose at tip 4 



4— Thorax cylindrical; pubescence of elytra conspicuous. 



Disc of thorax vaguely quadvituberculate; antennal spines well developed. 



protensus, Lee 

 Disc bituberculate at base, an elevated transverse line slightly in front of mid- 

 dle; antennal spines small prolixus, Lee. 



Thorax distinctly narrower at apex, the disc very roughly sculptured ; pubescence 



of elytra very inconspicuous calvatus, Horn. 



A. volitans Lee. New Species, 1873, p. 186. Brownish, sparsely clothed with 

 long pale pubescence. Thorax longer than wide, base and apex equal, sides feebly 

 arcuate, disc densely rather coarsely punctate. Elytra closely coarsely punctate, the 

 punctureis finer posteriorly, the apices truncate, the sutural angle acute not spiniform. 

 Tibiae with flying hair. Length .40 inch; 10 mm. 



The carinae of the outer joints of the antennae were said by Dr. 

 Leconte to be obsolete, in fact from an examination of the type I can- 

 not find that they exist at all. The spine of the third antennal joint is 

 two-thirds as long as the fourth joint, while that of the fourth is above 

 one-third the length of the fifth joint. 



This species is placed at the beginning as an expression of its close 

 relationship with some Elaphidion as acukatum and subpubescens and as 

 the genera constructed at the expense of Elaphidion are at present de- 

 fined there seems to be no reason why A. volitans should not be placed 

 near the species above cited, unless it be placed in Psyrassa Pascoe. 

 The latter genus and the value of its characters will be referred to later on. 

 One specimen. Lower California. 



A. tenuis Lee, Proc. Acad. 1854, p. 81. Brownish or piceous, sparsely cloth- 

 ed with white pubescence. Head very coarsely punctured. Thorax longer than wide, 

 base very slightly narrower than the apex. Sides feebly arcuate, disc coarsely and 

 deeply punctate, an indistinct smooth median line. Elytra coarsely and deeply but 

 not closely punctate, the punctures gradually finer toward the apex, the apices emar- 

 ginate, not spinose. Length .46 — .64 inch; 1 1.5 — 16 mm. 



The carinae of the outer joints of the antenna,* are very indistinct. 

 The third joint has a long spine equal to half the length of the fourth 

 joint, the other joints are mutic. This species should probably be placed 

 in Psyrassa, if recognized. 



Occurs in south-western Texas.
