Nov., 1904.] South American Hemiptera-Heteroptera. 199 



Leptoscelis bipustulatus Linn. Bartica Br. Guiana. Evidently 

 an abundant species as the collection from Mr. Parrish 

 included several dozen specimens and Mr. Van Duzee also 

 lists it. 



Leptoscelis nigripes Stal. Cochabamba, Bolivia, Aug., 1899. One 

 specimen, differs from Stal's description in being slightly 

 larger, IS mm. instead of 16 mm. 



Pthia cyanea Sign. Cochabamba, Bolivia. A very beautiful 

 species, brilliant iridescent blue-green with an orange-red 

 band on the pronotum. (Absent in two of the nine 

 specimens). 



Spartocera fusca Thtmb. Cochabamba, Bolivia, Aug., 1899. 



Spartocera denticulata Stal. Cochabamba, Bolivia. In some 

 points this agrees better with granulata, but in structural 

 details of genitalia it appears to belong here. 



Spartocera alternata Dall. Coroica Yungas, Bolivia. Picture of 

 diffusa Say to which it must be closely related. 



Plapigus foliaceatus Blanch. Coroica Yungas, April, 1899. Two 

 specimens which are dark fuscous rather than black and 

 have the anterior border of the pronotum, three longi- 

 tudinal stripes, the scutellum, costal border of elytra, dull 

 ferruginous brown, otherwise agrees well with Stal's 

 description. 



Margus sp. ''Quillota" Chili. An undetermined, possibly un- 

 described species received from Prof. J. C. Hambleton. 



Margus pectoralis Stal? Puno, Peru, Nov., 1898. A number of 

 the specimens of this species were received. They seem 

 to agree better here than with any other described species. 



Zicca nigropunctata De Geer. Cochabamba, Bolivia. Aug. and 

 Sept., 1899. 



Zicca rubricator Fab. Cochabamba, Bolivia, Aug. and Sept., 

 1S99.

 1899. Resembles atratus Dist. exactly for upper side

 num; legs marked somewhat with testaceous. 



Hypselonotus linea Fab. Bartica Br. Guiana, March 21, 1901. 

 Agrees perfectly with Fabricius' description. 



Hypselonotus fuscus n. sp. Coroica Yungas, Bolivia, April, 1899. 

 Pattern of linea above but light lines narrower, black areas 

 have luteous or ochreous ground so thickly covered with 

 black punctures as to appear dark fuscous where linea is 

 black. Antennae black. Beneath vellow testaceous, spot- 

 ted with black, spots round or oval in the two series each 

 side, legs densely annulate and spotted with black. 

 Length, 12 mm.
