^OLUS. 365 



(H. H. Smith), Almolonga, Jalapa, Tapachula (Hoge) ; Guatemala, Panzos, Teleman, 

 and Cubilguitz in Vera Paz (Champion) ; Nicaragua, Chontales (Belt, E. M. Janson). 



This is one of the commonest species of JEolus within our limits. The thorax has 

 a broad median vitta, narrowing posteriorly, and the sides to a greater or less extent, 

 black. The elytra have a broad oblique patch on the outer part of the disc a little 

 below the base, extending inwards to the second or third stria, a broad sharply 

 angulated fascia towards the apex, extending down the suture behind, and sometimes 

 a short sutural stripe at the base, black. In one specimen, from Cordova, the anterior 

 discoidal patch is connected with the post-median fascia. The supra-marginal carina 

 of the thorax is short. The scutellum is convex in front. A specimen from Atoyac 

 is figured. 



13. JEolus marginatus. (Tab. XVI. fig. 7.) 



Moderately elongate, shining, finely pubescent ; the head piceous, ferruginous in front ; the prothorax testa- 

 ceous, with a very broad median vitta abruptly narrowing behind, and a short marginal stripe, pitchy- 

 black ; the scutellum black ; the elytra testaceous, with a broad patch on the disc before the middle, 

 extending to the margin and connected inwards with a short sutural stripe running forwards to the base, 

 a broad sharply angulated fascia towards the apex, extending along the suture to the tip, and the lateral 

 margin from the base to the suture narrowly, pitchy-black ; the antennae testaceous, the basal third of 

 the epipleurae and the legs flavous, the under surface partly infuscate. Head convex, thickly punctured, 

 with a short carina on the vertex, the frontal carina rounded and moderately prominent; antennae about 

 reaching the hind angles of the prothorax, joint 3 a little longer than 2, the two together longer than 4. 

 Prothorax as long as broad, narrowed in front, the sides rounded anteriorly and sinuate behind ; the hind 

 angles strongly produced, acute, feebly divergent, carinate at the sides above, the carina rather short and 

 confluent with the marginal one at the tip ; the surface thickly, rather coarsely punctate. Elytra a little 

 more than twice the length of the prothorax, flattened on the disc, narrowing from the middle, conjointly 

 rounded at the apex ; coarsely and deeply punctate-striate, the interstices rather convex and roughly 

 punctured. 



Length 5|, breadth 1| millim. 



Hab. Mexico, Teapa in Tabasco (Pilate, in coll. Janson). 



One specimen. Allied to M. vermiculatus, from which it differs in having the head 

 and thorax more coarsely punctured, the thorax with the supra-marginal carina not 

 abbreviated behind, and the elytra coarsely and deeply punctate-striate ; the elytra 

 somewhat similarly marked, but with the margins black from the base to the apex, and 

 the post-median fascia more sharply angulate, the latter extending rather broadly down 

 the suture to the tip. The elytra have a curved patch at the base, an angulated fascia 

 a little beyond the middle, and a spot on the disc close to the apex, testaceous, the 

 black markings being very sharply denned. Less convex, shorter, and more parallel 

 than M. pulchellus, the discoidal vitta on the thorax broader and more abruptly 

 narrowed behind, the elytra margined with black, the scutellum flatter, &c.
