GLENIDION. 93 



may, however, be readily distinguished by its more transverse and more 

 pubescent thorax, as well as by the less deep striation of the head. 



From the neighbourhood of Ega (Kiver Amazon). Taken by Mr. 

 Bates. 



Genus 11. GLENIDION*. 



LABRTJM breve, subcirculare. 



PALPI MAXILLARES elongati, robusti, art. 2 do et 3 tio ad apicem oblique 



truncatis, apicali attenuate, conico. 



PALPI LABIALES elongati, minuti, attenuati, subcylindrici. 

 AxTEWMjiliformes (?), art. 3 tio et 4 to ceque ac 2 nd0 brevibus, & et & 



longioribus, attenuatis (reliqui desunt). 



CAPTJT breve, productum, vix depressum. 



THOKAX transversus, rectilinear is, ad basin leviter constrictus, ad lalera 

 marginatus. 



SCTJTELLUM minutissimum. 



ELYTRA parallela, elongata, subdepressa, glabra. 



PEDES : tarsi anterior es attenuati, vix dilatati, femora postica elongata ; 

 tibia? etiam elongatce et longitudinaliter (ad apicem) excavated; 

 tarsi, art. basalis productus et sat attenuatus (art. reliqui desunt). 



Elongate, subparallel, depressed. 



Labrum short, narrower than the base of the head, subcircular. 



Maxillary palpi elongate ; the basal joint minute, almost quadrate; 

 the second longer, obliquely truncate at the apex ; the penultimate 

 somewhat broader, more cylindrical, and also obliquely truncate at 

 the apex ; the terminal joint elongate and conical. 



Labial palpi elongate, minute. 



Antenna? approximate, inserted between the lower margins of the 

 eyes, probably filiform; the basal joint elongate, dilated, and sub- 

 incurved towards the apex ; the second shorter, somewhat narrower, 

 ovate ; the third as short as the second, and narrow ; the fourth and 

 fifth elongate, longer than the basal joint ; the rest are wanting in 

 the example before me. 



Eyes lateral, large, subglobose, situated at some distance from the 

 base of the head, and extending laterally as far as the anterior angles 

 of the thorax. 



Head short, transverse, not so much depressed from the plane of 

 the thorax as the preceding genus, Physimerus ; somewhat porrect. 



Thorax transverse (almostquadrate),rectilinear,slightly constricted 

 towards the base ; the anterior margin is obsoletely emarginate ; the 

 anterior angles depressed, the sides evenly marginate ; the base 



* y\r}vij, longurio.
