crickets appear to be somev/hat arboreal in their habits, and were 

 always seen upon the trunks of the pines from one foot to eight 

 feet above the ground. They were never observed upon the ground, 

 unless disturbed and forced to leap from the tree trunks. Very 

 often several crickets could be seen upon the trunk of one small 

 tree. The stridulations of these interesting crickets were heard 

 about sundown and in the early part of the night. These crickets 

 appeared to be very susceptible to weather changes and were 

 heard only on very warm evenings. 



The trill is loud, continuous, high-pitched, very much re- 

 sembling the trill of QLcanthus quadripiinctatus or (Ecanthus nigri- 

 ' cornis. In fact, when the writer first heard these crickets he was 

 inclined to believe he was listening to some species of (EcafitJnis. 

 Although in early June, 1914, Anurogryllus muticus appeared 

 to be very common in the pine grove mentioned, none were heard 

 a month later. They were not heard in this grove in 1915. This 

 species appears to be very uncommon in this region and has not 

 been located at any other point. 



Nemobiiis caroliniis Scudder. This tiny Nemohins is very 

 common beneath the leaves and grass of the roadsides throughout 

 the summer. Its stridulation is a weak, continuous trill indefinitely 

 prolonged. Great numbers of these crickets were trilling every- 

 where beneath the herbage of the roadsides in 1915. 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 difificult to capture. 



Neoconocephaliis rohustus crepitans (Scudder). This cone- 

 headed grasshopper is a very common species around Clarendon, 

 Virginia, in August. If the evenings are warm and humid, their 

 stridulations may be heard from sundown until well into the night. 

 The stridulations of this insect are somewhat puzzling. Two 

 well marked notes may be identified. The stridulations of the 

 majority of individuals around Clarendon and Washington consist 

 of a rather weak, continuous, snappy z-z-z-z-z-z. Occasionally, 

 however, other individuals produce an entirely different note 

 which is exceedingly loud, penetrating, and continuous, with a
