4. Elliptoleus crepericornis. 











Minor, angustior, a caeteris differt antennis nigro-fuscis articulis 3 basalibus tantum pallidis ; thorace fere ut 

 in E. curtulo qimdrato-ovato nee postice fortiter angustato (nt in E. vixstriato) nee valde elongato- 

 ovato (ut in E. flavipede) ; palpis pedibusque marginibusque thoracis et elytrorum testaceo-fulvis ; elytris 

 oblongo-ovatis, angustioribus, subparallelis, omnino obsolete striatis. 



Long. 2|-3 lin. 



Ilab. Mexico, Parada Capulalpam (Salle). 





5. Elliptoleus acutesculptus. 



Paullo major, niger vix senescens, antennis, palpis pedibusque piceo-rufis ; thorace breviter ovato, postice haud 



angustato, marginibus reflexis ; elytris subtiliter sed acute et integre striatis, interstitiis planissimis, 

 punctulis quatuor, tribus anterioribus juxta striam tertiam, quarto versus apicem in stria secunda 

 sitis. 

 Long. 4 lin. 



Hab. Mexico, near the city (Flohr in coll. Bates). 



GLYPTOLENUS.

GlyptolenuSy Bates, Proc. Zool. Soc. 1878, p. 595. 



" Corpus gracile. Caput angustum, ovatum. Mentum sinu dente magno elongato. Palpi nudi, articulis termi- 

 nalibus cylindricis. Thorax angustus, ante medium angulatim dilatatus, dorso grosse transversim rugatus. 

 Elytra ampla, convexa, apice baud sinuata, supra fortiter sulcata. Prosternum apice marginatum, promi- 

 nulum. Metasterni episterna elongata. Pedes graciles ; tibiae et tarsi fortiter sulcata ; tarsorum articuli 

 ]_us_4m latitudine sequales plantis pubescentibus, 4 US emarginatus." 



This genus was founded on a species remarkable for the strongly-sculptured trans- 

 verse rugae of the thorax. Since its publication I have found that Colpodes jantkinus 

 (Dej.), C. ater (Chaud.), and C. nigrita (Chaud.), in which the rugae are much less pro- 

 nounced, or the thorax entirely smooth, belong to the same group. 



by the linear but somewhat flattened and above deeply-grooved tarsi, the grooved sides 

 and outer edges of the tibiae, the convex, apically rounded elytra, and the narrow 

 lateral margins of the thorax. It is difficult to say whether these characters are 

 sufficient to distinguish Glyptolenus as a genus from so polymorphic a group as Colpodes ; 

 but I prefer to maintain it for the present. 



All are distinguished

The third elytral interstice has the normal three punctures ; but, being slightly 

 impressed, they are difficult to be distinguished from the transverse impressions or
