SUBFAMILY V. GRYLLINMO. 687 



It is also found beneath stones along the margins of lakes and streams. 

 I first discovered this insect through its stridulation, which was a high- 

 pitched continuous trill of considerable volume." 



Allard (1916a) says that about Clarendon, Va-, the tiny 

 Neinolihis carol-inns is very common beneath the leaves and grass 

 of the roadsides throughout the summer. Its stridulation is a 

 weak, continuous trill indefinitely prolonged. They are persistent 

 singers and may be heard throughout the night. In the coolness 

 of the early morning they appear to be especially musical. They 

 keep well concealed beneath the dead and matted herbage, and are 

 exceedingly difficult to capture." 



Owing to numerous wrong identifications by Scudder and the 

 confusion by him of the species above described as N. varicr/atus 

 with his N. carolitnis, the synonyms of the latter are numerous. 

 In addition to my Ncniobius cxiguus above cited, as placed by He- 

 bard (1913, 473), are N. septentrionalis Prov. (1877, 24), N. vola- 

 tlcus Scudd., female (1877, 36), N. a f finis Bent. (1894a, 249), \. 

 angustk-olUs Walker (1904, 186) and y. janiis Kirby (1906, 19). 

 It has been recorded many times under these synonyms, especially 

 that of N- exignus Blatch., a name used by Say for a species of 

 Anaxiplia and wrongly applied by Scudder (1862, 429) to Neino- 

 Mus fasc-iatus Saj T . Hebard in his Revision (1913) has given a 

 detailed account of the synonymy of this and other species of 

 NernoMus. Two races of N. carol inns are recognized by him, viz: 

 A 7 , c. brevicaudus Brunei* (1904, 57) from Colorado and N. c. neo- 

 inc.i-icaniis Scudd. (1896a, 100) from Texas, Arizona and New 

 Mexico.
