MUSEUM. 



Bt W. F. ROSENBERG. 



CEEAMBYCIDAE. 



1. Poecilopeplus martialis sp. nov. 



Head coarsely punctured, a deep longitudinal groove in centre, not reaching to 

 base. 



Thorax black; disc with five slightly raised flattened tubercles, a lateral tooth 

 as in P. ffircacens, but not so strongly developed ; anterior angle rounded, less 

 produced than mf.atescens; surface coarsely ])nnctured except on raised portions of 

 disc, which are nearly smooth. 



Elytra closely punctured, rugosely punctate at base; humeral angle not so much 

 raised as in F.flatescens. Straw-yellow; a black transverse band at base, not quite 

 extending to suture, narrowest laterally, not rj^uite reaching margin; a second trans- 

 verse black band before the middle, extending from the margin, but not reaching 

 the suture ; a third band situated at three-fifths of the distance from the base, and a 

 large triangular black spot at the apex. 



Under surface and legs black; tarsi beneath dark brown. 



Long. 32 mm.; lat. hum. 13 mm.; antennae 18 mm. 



Ilab. Costa Rica. Type in the Triug Museum, under the above name, whicli I 

 have adopted. It may be distinguished from P. Jlanescens by the very different 

 position of the tliird band on the elytra and by the apical spot; all the bands are 

 much broader and regular in shape. 



2. Poecilopeplus flavescens sp. nov. 



Head closely punctured, smoother on top. Thorax black, dilated at sides; a 

 blunt tooth-like lateral process about the middle; anterior angles well produced, 

 rounded; sides slightly depressed above lateral tooth: centre of disc raised; a sliglit 

 tubercle on each side of disc, near the base and above lateral tooth; both margins 

 ridged; surface deeply punctate, except on raised portion of disc. 



Scutellum black, finely punctured. 



Elytra with three fine longitudinal raised lines, the inner one commencing at 

 the edge of the black basal band, gradually inclining towards the suture but not 

 touching it; it does not quite reach the apex; the second commences above the 

 ridge of the humeral angle and runs parallel to the first; it is a little longer and is 

 forked at the end; the outer line has its origin behind the humeral angle, and is 

 very short, becoming lost on entering the second black band. The humeral angles 

 are raised longitudinally. Surface of elytra thickly punctured, with several depres- 

 sions between the basal band and the middle one. General colour "gallstone 

 yellow " (Ridgway); a broad irregularly shaped transverse black band at base, not quite
