Diagnosis.— Among the species of Melanaethus with the large 

 terminal modification of the peritreme this one may be recognized 

 by the fact that the punctation on the middle of the posterior pronotal 

 lobe is much finer than that found laterally and that the costae, which 

 are straight and subparallel on the basal half, are neither explanate 

 nor recurved. 



Description.— Male: Elongate, widest behind midlength. 



Head: Length two-thirds width, 0.62(0.60-0.66): 0.96 (0.94-1. 01); 

 interocular width, 0.63(0.63-0.66); anterior outline a flattened semi- 

 circle, clypcus very slightly longer than juga, weakly narrowed apically ; 

 juga, clypeus and interocular space variously punctate; with fine, 

 distinct, marginal caiina dorsally; ocelli small, separated from e3^e 

 by space about three times transverse ocellar width; jugum ventrally 

 dull or shining, maxillary plate strongly alutaceous. Antennal seg- 

 ments: I, 0.18(0.17-0.21); II, 0.19(0.16-0.22); III, 0.23(0.22-0.24); 

 IV, 0.32(0.30-0.34); V, 0.36(0.36-0.40). Bucculae almost twice as 

 high as labial IT, abruptly terminated posteriorly; labium reaching 

 middle of mesosternum. Labial segments: I, 0.26(0.25-0.27); II, 

 0.44(0.43-0.46); III, 0.30(0.30-0.32); IV, 0.27(0.23-0.30). 



Pronotum: Length more than half width, 1.11 (1.04-1.17) :2.08(2.02- 

 2.15); anterior margin moderately, simply emarginate; lateral margin 

 straight on basal third or half, with submarginal row of seven or 

 eight setigerous punctures; transverse impression virtually absent, 

 its postmedian site not marked by special row of punctures; anterior 

 lobe with numerous strong punctures subapically and laterally, 

 elsewhere with scattered minute punctures; posterior lobe minutely 

 punctured medially, more strongly so laterally. 



Scutellum: Longer than wide, 1.42(1.36-1.46) : 1.25(1.17-1.30); disc 

 polished, with scattered small punctures absent in basal angles, be- 

 coming more numerous apically. 



Hem elytron: Clavus and corium polished; clavus with two or three 

 rows of punctures; mesocorium with two complete rows of punctures 

 paralleling claval suture, large punctures of main area becoming very 

 coarse basally; exocorium more abundantly punctate, declivent basally 

 to flattened costa; costa without setigerous punctures; membranal
