though usually in such material the tegmina are distinctly shorter. 

 That author gives five spines for the dorsal margin of the caudal 

 femora, this is unusual for the species and found in but few speci- 

 mens before us; it is very possible that he included the dorso-external 

 spur, which equals in size the marginal spines. Saussure's iiiicro- 

 nicgas is based on a small micropterous specimen with ovipositor of 

 minimum length; hrcvipcnnis a larger pale micropterous individual 

 showing nearly the maximum of tegminal abbreviation, and parvi- 

 paiiiis similar but with tegmina somewhat less abbreviate. The pres- 

 ence (brevipennis) or absence (parz'ipcnnis) of a foramen on the 

 inner face of the cephalic tibia has caused these two names to be 

 placed in different genera: this is a condition now known to be vari- 

 able within the species. In addition to the variants referred to above, 

 we find in the present species some slight variation in the size and con- 

 vexity of the head, form of maxillary palpi (varying in the oblique 

 truncation of the distal segment, which reaches to a point from slightly 

 less than to a little beyond the middle of the ventral margin) and 

 proportions of the caudal femora, which would be expected in a plastic 

 species enjoying so extensive a distribution and which, accompanied 

 by the varied appearance mentioned above, apparently led Saussure 

 to describe the three specimens before him as distinct. 



The types before us of Scudder's Nemohins distingucndus and 

 dclicatus leave no room for doubt. That author, evidently through 

 sheer carelessness, forgot the character which so definitely separates 

 the Nemobiites from the Gryllites. Absence or presence of elongate 

 wings are the additional factors principally responsible for the two 

 names. 



This small, usually dark species, which has generally been deter- 

 mined as pusillus by authors, is one of the most variable and widely 

 ranging of the American Gryllidae. The features most worthy of re- 

 mark are as follows : Head little broader than pronotum, slanting and 

 scarcely convex from summit of occiput to the large but not strongly 

 produced interantennal protuberance ; strikingly huffy, narrow, di- 

 vergent lines run back from lateral ocelli. Maxillary palpi rather 

 heavy, distal segment obliquely truncate ; palpi blackish except fourth 

 and proximal portion of fifth (distal) segment, which portions are
