vary considerably in size and color. Several of the species are aquatic, 

 or at least semiaquatic, in habit. 



The present collection contains only a small number of South Amer- 

 ican species. Possibly several of these are new and accordingly are 

 described herewith. A table for separating all of the forms known to 

 occur on this continent would undoubtedly be of considerable value 

 to future workers, but until more material is available for the purpose 

 I deem it hardly advisable to attempt the compilation of such a 

 synoptical table. In August, 1913, Mr. Morgan Hebard published 

 a revision of the species of the genus found in North America north 

 of the Isthmus of Panama (r/. Proc. Acad. Nat. Sci. Philad., June, 

 1913). That very carefully prepared paper will be of much assistance 

 in a similar study of the South American species. 



25. Nemobius meridionalis sp. no v. 



A medium-sized, smooth-bodied or glabrous insect, with prominent 

 white spots on the upper edges of all the femora. The ovipositor is 

 short and straight, much shorter than the hind femora, and its apex 

 is evenly and finely serrated above. The tegmina are variable but some- 

 what shorter than the abdomen, the wings when present are caudate 

 and greatly surpassing both the cerci and the tip of the ovipositor. Pro- 

 thorax narrower in front than behind, with a well-defined humeral 

 pale band; below this the sides are piceous, while the lower edge is 

 broadly pale; disk somewhat conspersed with paler. Occiput more 

 or less plainly pale quadrivittate. Head a little wider than the front 

 edge of the pronotum, the eyes rather prominent. 



General color above piceous, varied more or less on the pronotum 

 and below with pale testaceous in some specimens, the humeral angle 

 and costal area of the tegmina are varied with a greenish tinge. The 

 tibiae are fasciate with light and dark, and the tarsal joints have their 

 apices dark. Hind femora pale brown and testaceous, their upper 

 edges prominently tripunctate with dirty white, these light-colored 

 markings being located just beyond stiff dark-colored hairs or bristles. 

 The third dorsal abdominal segment before the apex is provided on 

 each side with a large white spot. 



Length of body, 9 mm.; of pronotum, 1.5 mm.; of tegmina, 4-5.25 

 mm.; of wings when present 19 mm.; of hind femora, 7 mm.; of ovi- 

 positor, 4.5 mm.
