132 ENDOMYCHID^. 



Var.1 (vel alterius sexus). Antennis paullo longioribus, articulis quatuor basalibus rufis. 



Sab. Guatemala, Teleman in Vera Paz (Champion). 



The short form, distinctly punctured thorax and elytra, stout antennae with the club 

 " connate," i. e. with the joints not laxly articulate, and the sides of the thorax very 

 finely margined (without a band as in Stenotarsus), distinguish this species from the 

 allied forms. It might be taken for a very small Anidrytus. The head is nearly 

 smooth. The antennae are about half as long as the body, their joints 3-5 very little 

 longer than wide, the second, sixth, seventh, and eighth bead-shaped, the club hardly 

 wider at its commencement than the eighth joint, but gradually increasing in width. 

 The thorax is twice as wide as long, the sides considerably rounded in front, the hind 

 angles a little acute, the sulci distinct and slightly arcuate, the punctures small but 

 quite distinct. Scutellum faintly punctate. Elytra distinctly and evenly punctured, 

 the punctuation obsolete on the apical third ; there is a very fine, not deeply impressed, 

 sutural stria. 



This insect is, unlike other Ephebi I have seen, almost smooth. The example from 

 Teleman only differs in the structure of the antennas, and this is probably of sexual 

 import only. There is only one specimen from each locality, and it would be perhaps 

 impossible upon these to decide whether or not they are the sexes of one species. The 

 example from Zapote is taken as the type. 



2. Ephebus chontalesianus. (Tab. vm. fig. 2.) 



Oblongo-ovatus, ferrugineus, prothoracis disco parcius minute, lateribus prsesertim ad angulos posticos crebre 

 punctatis; elytris parcius rufo-pubescentibus ; antennis nigris, articulis quatuor basalibus rufis. Long. 

 5 millim. 



Hob. Nicaragua, Chontales (Jansori). 



In this insect the antennae have four joints clear rusty-red and the following ones 

 black ; it is thus clearly distinct from E. cardinalis or either of the species described 

 by Gerstacker. The antennal joints are all rather short, the third and fourth being 

 equal, and each a little longer than the second, the fifth to the eighth not longer than 

 wide, the club gradually widened and compact, the apical joint subquadrate. The 

 thorax is depressed, the basal sulci short ; the sides narrowing in front, nearly straight 

 for three-quarters their length, then suddenly rounded in to the front angles, their 

 edges a little reflexed ; the excision for the head has a very fine marginal line. A 

 single specimen. 



SYST^ECHEA. 



Characteres plerumque ut in Stenotarso. Antennae articulo tertio quara secundus vix longiore, quarto ad 

 sextum his subsequalibus, octavo transverso; clava magna, laxe articulata. Palpi maxillares articulo 

 ultimo subulato. Prosternum : processu latiusculo, apice sulcato-impresso. Mesosternum transversum. 

 Pronotum transversum, tenuiter marginatum, sulcis basalibus leviter impressis, angulis anticis acutiusculis, 

 modice productis.
