15. Catasarcus memnonius. 



Shortly ovate, black, nitid, without any scales; front 

 short, obscurely marked with five grooves, a median, 

 and two approximate ones on each side, the carina near 

 the eye obsolete ; rostrum with a somewhat circular im- 

 pression on the basal half; pro thorax short, ti-ansversely 

 tuberculate, the tubercles fiat, smooth, much broader 

 than long, no punctures, and scarcely grooved, or the 

 anterior transverse groove very faintly marked; scutel- 

 lum equilaterally triangular ; elytra transversely grooved 

 at the sides, but somewhat seriate-pimctate towards 

 the suture, the punctures very indeterminate, the inter- 

 vals irregularly tuberculate, the tubercles arranged in 

 longitudinal rows, post-humeral spine stout, conical; 

 body beneath, dark pitchy, a patch of white scales on 

 each side of the metasternum ; abdomen finely granulate ; 

 legs and antenna) reddish-pitchy, with blackish setaceous 

 hairs. 



Length 4 lines. 



Hah. — Victoria, 



Germar's description of his 0. transversal is, in regard 

 to the prothorax " Vage et rugoso-punctatus," scarcely 

 agrees with what I take for it, unless we suppose that 

 the roughness applies to the irregular surface of the pro- 

 thorax caused by the transverse grooves; in G. memno- 

 iiius, the direction of the impressions on the elytra 

 a}>pears to vary according to the position in which it is 

 viewed, but the tubercles have less of the longitudinal 

 arrangement, and there are no scales whatever in the 

 grooves. 



16. Catasarcus ovinvs. 



Shortly ovate, black, covered with grayish scales; 

 front above the transverse sulcus elongate, with four long 

 well-marked carina); rostrum ^\^th the central carina 

 gradually broader beneath, gradually passing into the 

 triangular apical plate ; prothorax rather short, the scales 

 slightly condensed at the sides ; scutellum very small, 

 equilaterally triangular; elytra seriate-punctate, the 

 punctures large, shallow, a)ul distinctly limited, the in- 

 tervals transversely tuberculate; body beneath, and legs.
