^EOLUS. 369 



The thorax has a broad median vitta, narrowing behind, and the sides narrowly, piceous 

 or black. The elytra are comparatively short, and exceedingly coarsely punctate- 

 striate. JE. trilineatus is a close ally of JE. circumscriptus, which has the scutellum 

 similarly formed ; but differs from it in having the elytra very coarsely punctate- 

 striate, and the thorax with a dark marginal stripe. 



19. iEolus yucatanus. (Tab. XVI. figg. 14, 14«.) 



Elongate, rather depressed, shining, finely pubescent ; rufo-testaceous, the head and scutellum black ; the elytra 

 with the base narrowly, a short, narrow, oblique stripe extending from the shoulder to the middle of the 

 disc, and a rather large subquadrate spot on the disc towards the apex — incised in front and behind, and 

 obliquely placed, — black; the antennae and legs flavo-testaceous, the under surface ferruginous. Head 

 convex, thickly, somewhat coarsely punctate, the frontal carina rounded and moderately prominent; 

 antennse extending to a little beyond the hind angles of the prothorax, joint 3 longer than 2, the 

 two together longer than 4. Prothorax slightly longer than broad, narrowed in front and behind, 

 the sides feebly rounded from the middle forwards and strongly sinuate before the base ; the hind angles 

 very narrow, strongly and acutely produced, divergent, finely carinate at the sides above, the carina very 

 short and confluent with the marginal one at the tip ; the surface thickly, somewhat coarsely punctate, 

 the punctures a little more scattered along the middle of the disc. Scutellum with a smooth rounded 

 prominence in the middle. Elytra two and one-fourth times the length of the prothorax, narrowing from 

 about the basal third, and conjointly rounded at the apex ; coarsely punctate-striate, the interstices rather 

 convex and sparsely punctured.

Hab. Mexico, Yucatan [Pilate, in coll. Janson). 



One specimen. This very distinct species is allied to JE. trilineatus and JE. obliquus, 

 Cand. The hind angles of the thorax are unusually narrow and very acute, with the 

 carina extremely short and fine. The elytra! markings resemble those of M. obliquus, 

 except that the short oblique stripe on the disc at the base starts from the shoulder, 

 instead of from the suture. The scutellum is conically raised in the middle, as in 

 JE. trilineatus.

" Ni^er subnitidus, griseo-pubescens ; fronte punctata ; antennis rufis ; prothorace latitudine longiore, basi 

 apiceque leviter angustato, sequaliter sat dense punctato, margine antica angulisque posticis rufis ; elytris 

 punctato-striatis, interstitiis rugosis, maculis quatuor rufis ; pedibus flavis.— Long. 7, lat. 14- millim."

Allied to the South- American JE. designatus, Cand. We are indebted to Dr. Cand 

 for the loan of the type of this species.
