146 ORTHOPTERA OF MAINE. 



apex to the base, internal border full and curved evenly from tbe base to the 

 tip ; in the female, wing-covers reaching to about the middle of the abdomen, 

 narrow, pointed at the tip, with a sudden expansion about the middle of the 

 costal border, internal border as in the male ; wings alike in both sexes, small and 

 nearly abortive; abdomen compressed laterally, with a distinct median carina. 



Male : head above, dorsum of the pronotum, sides of the meso- and meta- 

 thorax, face and sides of the head below the eyes, and wing-covers, light lilac- 

 brown, varying in intensity somewhat in different specimens; sides of the 

 head between the eyes and the pronotum shaded with black ; antennae 

 brown, darkest at tip ; sides of the pronotum, and of tbe first two or three 

 abdominal segments shining blacla; abdomen above light brown banded with 

 black, below light yellow, sides, except on the first two or three segments, 

 dark reddish brown; fore and middle legs brown; hind femora above light 

 yellowish brown with one or two broad dark brown bands, below light yellow, 

 apex black ; hind tibiae yellowish red, black at tip and base. 



The female differs from the male in being darker and in wanting most of 

 the black upon the sides of the pronotum; head, ^dorsum of pronotum, and 

 wing-covers frequently mottled or even blotched with dark brown; sides of 

 the pronotum like the dorsum excepting a small patch of black upon the upper 

 posterior angle. From dry specimens.

' I The anal appendages of the female of this species are very unlike those of 



' any other known New England Orthoptera, and lead me to suspect it to be gen- 

 erically distinct from the two Connecticut species referred to this genus. The 

 appendages are quite short, extending but slightly beyond the last segment 

 of the abdomen. Each of the superior appendages has the upper posterior 

 surface quite broad, and furnished at the tip with a stout sharp tooth strongly 

 curved upward ; three saw-like teeth along the outer edge, decreasing in size 

 toward the base, and in some specimens the last tooth wanting; near the mid- 

 dle a stout transverse tooth extending two-thirds of the way across the sur- 

 face, and between this and the base one or two more small teeth. The inferior 

 appendages have each a strong hooked tooth at the tip, and one or two small 

 ones on the outer edge near the base. 



This structure of the female appendages is beautifully adapted to a remark- 

 able habit in the manner of depositing the eggs, which seems not to have been 

 noticed before among Orthoptera. The eggs are deposited in old logs, in the 

 undersides of boards, or in any soft wood lying among the grass which these in- 

 sects inhabit. By means of the anal appendages the female excavates in the 

 wood a smooth round hole about an eighth of an inch in diameter. This hole 

 is almost perpendicular at first but is turned rapidly off in the direction of the 

 grain of the wood, and runs nearly parallel with and about three-eighths of an 

 Inch from the surface ; the whole length of the hole being an inch or an inch 

 and" a fourth. A single hole noticed in the end of a log was straight. , The 

 eggs, which are about a fourth of an inch in length, quite slender and light 

 brownish yellow, are placed in two rows, one on each side, and inclined so 

 that, begining at the end of the hole, each egg overlies the next in the same row 

 hy about half its length. The aperture is closed by a little disk of a hard 

 gummy substance. I have seen many of the females engaged in excavating 

 the holes, and they always stood with the body in the direction of the grain 

 of the wood, and apparently did not change their position during the opera- 

 tion. When one was just beginning a hole it was very easy to see the upper 

 appendages rise and open, and each time scrape away a little of the wood. 

 During this operation a froth y fluid is emitted from some part of the abdomen, 

 but whether it serves to soften the wood or to lubricate the appendages and 

 the sides of the hole, I did not determine. There were always great num-
