SOUTH AMEEICAN PHYTOPHAGOUS COLEOPTERA. 273 



Larger than any of the Colombian species described by 

 Lefevre in the Munch. Mittheilg. from the same locality ; the 

 basal joint of the antennae black above, and the elytral punctua- 

 tion very fine. N. pustidata, Har., of which the female has been 

 described only, has four tubercles below the shoulders of the 

 elytra, and the sides of the thorax are impunctate ; N. bogotana, 

 Har., has strongly punctured elytra, and the apex of the tibiae 

 and the tarsi fulvous. I possess two males and one female 

 specimen of the species described here. 



Syphaxia maculata^s]). nov. (Galerucinae). 



Robust, elongate and parallel, fulvous ; antennas black, the apical 

 joints fulvous ; thorax transverse, sulcate, finely pubescent, with two 

 black spots ; elytra greenish, opaque, finely rugose, each elytron with 

 eight fulvous spots. Length, 13 mill. 



Of broad subcylindrical shape ; the head fulvous, broad, very finely 

 rugose between the eyes, the latter rather small, oblong, entire, frontal 

 elevations only indicated ; antennas stout, not extending to the middle 

 of the elytra, black, the apical three joints fulvous, third joint the 

 longest, the following joints gradually shortened ; thorax three times 

 broader than long, the anterior margin strongly concave, the sides 

 rounded and widened at the middle, the angles not produced, the 

 surface deeply sulcate at the sides and longitudinally so at the middle, 

 the impressions very finely pubescent, the base with two obscure 

 blackish spots, rest of the surface not perceptibly punctured ; scutellum 

 broad, fulvous, its apex broadly rounded ; elytra convex, wider at the 

 base than the thorax, very finely rugose and punctured, opaque and 

 pubescent, greenish, with eight fulvous spots placed as follows : one 

 at the base, two before the middle, slightly oblique, one of narrow and 

 elongate shape below the shoulders, three placed triangularly below 

 the middle, and one at the extreme apex of each elytron ; below and 

 the legs fulvous, impunctate and scarcely pubescent ; legs very robust, 

 the tibiae longitudinally sulcate, the first joint of the posterior tarsi 

 very slightly longer than the second ; claws simple, thickened at the 

 base ; prosternum invisible between the coxas, the anterior coxal 

 cavities open. 



Hab. Calanga, Peru. 



Syphaxia is the only genus in which this handsome species, 

 of which a single specimen is contained in my collection, can be 

 placed ; the shape of the antennae, that of the thorax, and the 

 less dilated elytra does not entirely agree with the typical 

 form, which, however, in themselves would not be sufficient to 

 separate the genus. On the other hand, the general structural 

 characters, and of all, the simple claws, robust legs, and open 

 coxal cavities agree with Syphaxia. The specimen before me is 

 probably a female, the last abdominal segment being deeply tri- 

 angularly emarginate at the apex.
