rounded, surface punctured as in ocreatus Horn, but with four subsutural 

 striae at middle on each elytron, basal tubercles feebly developed, jjost- 

 scutellar depression feeble. Abdomen finely, remotely punctate, closer and 

 coarser at the sides. Length, 6.5 mm.

 (No. 167), in my collection. 



Allied to E. ocreatus Horn, l)ut the form is much more slender, 

 the s('ul])ture of the elytra and alxlomen finer and the elytral 

 apices with the conspicuous jrray liaii-s of that species wanting. 



Enoclerus lautus new species 



]*]longate, shining, head, prothorax, basal fifth of elytra, trochanters, tibiae 

 and tarsi rufous; the head with a broad black maculation starting on middle 

 of front and furcate upon occiput; thorax with two large rounded black dis- 

 cal maculations, a smaller one each side on the flanks, these all narrowly con- 

 nected; elytra with a transverse median fascia, arcuate upon each elytron, 

 comijosed of white pubescence, the rufous basal portion bordered ])osteriorly 

 and the apical fifth clothed with white pubescence, vestiture elsewhere com- 

 j)()sed i)rincipally of long erect black hairs. Head, including the eyes, slightly 

 narrower than prothorax at widest part, rather evenly and closely punctate, 

 front with two well developed longitudinal impressions; antennae red, man- 

 dibles black. Prothorax very slightly longer than wide, more finely and 

 sparsely punctate than the head. Elytra one-fourth wider than prothorax, 

 sides feebly divergent from basal sixth to apical fifth, apices separately round- 

 ed, post-scutellar region feebly depressed, surface rugulose, finely punctate, 

 coarsely, sparsely so at base. Posterior margin of abdominal segments pale 

 yellow. Length, .ify mm.

The relationship of this species to the other members of the 

 genus is difficult to indicate; it is perhaps best placed in prox- 

 imity to E. pinus Schaeffer. 



The species of Erioclerus allied to nigrifrons Say and nigripes 

 Say appear to be about the most misunderstood, and in collect- 

 ions the most confused, species of this ratluM- extensive genus. 

 The following table is offered as an aid lo Iheii' recognition: 



A. Elyta black with one or two, usually interrupted, whitish fasciae; moder- 

 ately robust,
