50. Gryllacris africana Brunner. 

 Gryllacris africana Brunner, I. c, pp. 325. 362 (1888); Kirby, I. c, p. 147 (1906). 

 A pair, male and female, from Lolodorf, taken by A. I. Good in 

 May, 1914, are referred to G. africana Brunner. C. M. Ace. No. 5264. 



Family HETRODID.E. 



The representatives of the family Hetrodidae are remarkable in 

 appearance. Many of them are ornamented with long spine-like 

 projections on the disk and along the borders and lateral carinse of 

 the pronotum, while others have this part smooth. The group is 

 native to the continent of Africa, to southern and southeastern 

 Europe, and southwestern Asia. Fourteen genera have thus far been 

 recognized and described by orthopterists, and fifty-seven species 

 assigned to them. 



51. Cosmoderus ? sp.? 



A single very immature nymph is contained among the specimens 

 collected by F. H. Hope at Batanga. It was taken in March, 1914. 

 C. M. Ace. No. 5293. It seems to be referable to the genus Cos- 

 moderns rather than to any other. It is chiefly deep shining black, 

 with the anterior and median femora almost wholly, and the posterior 

 ones on their apical two-fifths or one-half, pale testaceous. The 

 median and posterior tibiae are also largely tinged with this color, 

 except at their base and apex. The antennae are robust at base and 

 slender apically, the basal ten joints are black, while those beyond are 

 pallid. Both the disc of the pronotum and the dorsal portion of the 

 abdominal segments are very conspicuously longitudinally carinated, 

 giving the insect a peculiar corrugated appearance. Whether this 

 individual is the young of one of the described species, or new, I 

 cannot say. 



Family PYCNOGASTERID.F:. 



This is also an Old World group of the Tettigonoidea and is confined 

 chiefly to the Meditteranean region. These insects are wingless, or 

 almost so, being provided with these appendages only in the form of 

 stridulating organs almost covered by the pronotum, and present in 

 both sexes. According to Kirby's Catalogue of the Orthoptera there 

 are eighty-eight recognized species, distributed among eight genera.
