NO. 1124. REVISION OF THE MELANOPLI SCUDDEB. 285 



There is but a single annual brood which begins to appear full fledged 

 in ]STew England late in July. According to Kiley, the eggs are not 

 laid in a single mass, but at intervals in several; he has twice obtained 

 four successive pods from a single female, covering a period of nearly 

 two months and containing eggs amounting in all to from ninety-six to 

 one hundred and ten. The eggs have a quadrilinear arrangement in 

 the pods. 



At Andover, Massachusetts, on October 5 many years ago I observed 

 a pair of this species, male and female, near together alternately sig- 

 naling to each other with a slight quick movement of the hind legs 

 upon the tegmina, as if stridulating. I made no note of whether any 

 sound was actually produced and do not now recall any. 



Many interesting notes regarding this species will be found in the 

 first report of the United States Entomological Commission.

Of medium size, closely resembling the preceding species in colora- 

 tion, but generally of a somewhat lighter tint. Head a little promi- 

 nent, flavo-testaceous, generally more or less infuscated above, with 

 a postocular band; vertex tumid, the interspace between the eyes 

 scarcely broader than (male) or half as broad again as (female) the 

 first antennal joint; fastigium steeply declivent, distinctly (male) or 

 rather shallowy (female) sulcate; frontal costa just failing to reach the 

 clypeus, subequal, of the width of the interspace between the eyes, 

 sulcate at and (especially in the male) below the ocellus, biseriately 

 punctate above; eyes moderately prominent in both sexes, much 

 longer, in the female very much longer, than the intraocular portion of 

 the genae; antennae ferruginous, feebly infuscated apically, five-sixths 

 (male) or less than two-thirds (female) as long as the hind femora. 

 Pronotum slightly and regularly enlarging from in front backward, the 

 disk feebly convex and passing into the anteriorly feebly tumid, ver- 

 tical, lateral lobes by a well-rounded but abrupt shoulder, the disk 

 brownish fuscous, more or less feebly ferruginous, the lateral lobes dull 

 luteo- testaceous, with a broad postocular band on the prozona; median 

 carina slight and percurrent, feebler on the prozona than on the rneta- 

 zoua; front margin subtruncate, very faintly flaring at least in the 

 male, hind margin obtusangulate, the angle well rounded; prozona 

 feebly longitudinal (male) or feebly transverse (female), scarcely if any 

 longer than the closely but shallowly punctate metazona. Prosternal 

 spine rather long, suberect, appressed cylindrical, blunt, rather longer 

 and less appressed in the male than in the female ; interspace between 

 the niesosternal lobes twice as long (male) or less than half as long
