the herbage, grasses, and reeds of field and meadow. Their 

 bright, grass-green colors appear very conspicuous and clearly 

 defined against the white- papered background of an insect 

 cabinet. Yet in their haunts among the tangles of luxuriant 

 marsh grasses and reeds, where their green, elongate bodies 

 and wings assimilate with the lights and shadows of green and 

 shining stems and leaves, a most painstaking search will hardly 

 reveal them. 



The stridulations of the species of Conocephalus, like the 

 notes of all the L,ocustidae, entirely lack any musical tone or 

 trill so characteristic of the crickets. Their notes are always 

 loud, buzzing, and penetrating, and differ not so much in 

 sound-quality as in the manne'r of delivery. The notes of all 

 species may be definitely classed as intermittent or prolonged. 

 These insects are persistent singers, and most species stridu- 

 late most actively at night. 



At Thompson's Mills, north Georgia, one of the first insect 

 notes of springtime is produced by Conochepha/u^fitsco-stri- 

 atus Redtenbacher. Here I have recorded the notes of this 

 locust as early as April 18. It sings entirely by night, and 

 occurs scatteringly in nearl)' all grassy situations. I find it 

 more common in the fields of young wheat than elsewhere, 

 although I have taken individuals on the high blackberry and 

 other vegetation. Its note is a strong, penetrating, metallic 

 z-z-z-z-z-z-z-z-z-z-z-z-z-z indefinitely prolonged and audible 

 at long distances. This insect is very shy and takes to 

 long flights when disturbed. During the warm April nights 

 its notes are among the most persistent and characteristic 

 sounds of that season at Thompson's Mills. 



Another species which I have taken at Thompson's Mills is 

 Conocepkalus bruneri Blatchley. (Plate, V, fig. 2.) Here, one 

 night in July, 1909, I took a single male of this species from 

 some grasses and weeds in a wet spot by the roadside. I was 

 led to its hiding place by its persistent stridulations. The notes 

 of this Conocophalus are very strong, sharp, and intermittent 

 -zip-zip-zip-zip and rather briskly repeated. Its notes 

 are stronger than those of C. ensiger Harris. C. bnnieri does 

 not appear to be common at Thompson's Mills, for a persis- 

 tent watch has revealed only this single individual. 



The species Conocephalus exiliscanornus Davis (PI. V, fig. 

 2), which appears hardly distinguishable from Conocephalus 

 bruneri,* is more or less common around Washington, D. C., 



*Were it not for a noticeable difference in stridulation C. bruneri and 

 C. exiliscanornus would he unhesitatingly pronounced synonymous. 

 Specimens which may be classed as one or the other species are hardly 

 distinguishable from morphological characters.
