the present one may be distinguished by the impunctate epi- 

 steme, smooth head in connection with tlie basal elevation of 

 the elytra and their punctuation. The nearest aUied species 

 seems to be R. frontalis Baly, which has however a strongly 

 punctured episteme and thorax. 



19. Rliyparida, trilineata, Baly. 



This species, one of the largest of the genus, seems sui)ject 

 to considerable variation , if indeed the four specimens contained 

 in the Genoa Civic Museum do not represent a different but 

 allied form. They differ in being of a uniform dark fulvous 

 colour, the thorax being slightly darker and not coarsely (as 

 M.^ Baly says) but finely and rather closely punctured; this 

 character agrees however with a normally coloured specimen 

 contained in my collection, which differs again as well as the 

 specimens received from Genoa in the perfectly impunctate in- 

 terspaces of the elytra which M.^" Bai}' describes as minutely 

 punctured. 



New Guinea, Katau, Fly River (L. M. D'Albertis). 



20. Ptlxyparida mox'osa,, n. sp. 



Broadly -ovate, dark bluish black. Four basal joints of the an- 

 tennae, fulvous. Thorax distinctly punctured, its sides straight. 

 Elytra more or less strongly punctate-^triate anteriorly, more 

 finely posteriorly. 



Length 3 lines. 



Head convex, extremely finely punctured at the vertex, the 

 epistome scarcely separated from the face, broader than long, 

 closely and rather strongly punctured, its anterior margin very 

 moderately concave; labrum fulvous. Antennae half the length 

 of the body , the first four or five joints fulvous , the rest black 

 and rather short and slightly thickened. Thorax twice as broad 

 as long , the sides perfectly straight and strongly narrowed from 

 base to apex, but very little dellexed anteriorly , all the angles
