34f3 MR. R. 8HELF0RD OX A COLLECTION OF 



The apex of the abdomen in the unique speeimen is somewhat obscured by 

 clouding o£ the amber and by enclosed foreign particles, but I trust 

 that I have succeeded in making out the details ol: structure successfully. 

 Asymmetry of the supra-anal lamina in the Blattidpe is unusual, but by no 

 means unknown (cf. Anisop//(/ia jucunda, Sauss.) ; wher*? it occurs it serves 

 to mark a species very distinctly. 



Phyllodromia furcifera, sp. n. (PI. 47. fig. 13.) 



(J . No. 5539. ? . No. 674.0. 



Piceous. Antennpe longer than total length. Pronotnm trapezoidal, 

 without pale margins. Tegmina rather narrow, not exceeding the apex of 

 abdomen by much, outer margins not pale. Sub-genital lamina ( c? ) pro- 

 duced, asymmetrical ; both styles, which are strongly chitinized, situated on 

 the left side, the left style is slender and sharply pointed, the right style is 

 larger, stouter, and bifurcate ; ( $ ) semiorbicular, ample. Cerci slender, 

 with 12 visible joints, exceeding apex of tegmina. Front femora with a 

 complete row of spines on anterior margin beneath, 4 spines on posterior 

 jnargin : mid- and hind-femora with 4-5 spines on both margins beneath. 



Formula of apical spines j, j, p no genicular spine on front femora. 



Total length {S & ? ) 16 mm. 



The genital styles are remarkable, and I know of no recent species of the 

 genus with styles at all like them ; they recall, however, the genital styles of 

 some W. African species of Stylopyga recently described by me. 



Phyllodromia baltica, sp. n. (PI. 47. fig. 14.) 



S . No. 5419. 



Dark castaneous. Antenna3 longer than total lenoih. Vertex of head not 

 covered by pronotnm. Prouotum trapezoidal, posteriorly very obtusely 

 produced, lateral margins not hyaline. Tegmina not exceeding the apex of 

 abdomen by much, about 12 costals; discoidal sectors oblique, numerous; anal 

 vein well marked. Sub-genital lamina produced and very asymmetrical ; 

 two slender styles, the left slightly stouter than the right. Cerci rather 

 stout, exceeding the apex of the tegmina, with only 9 visible joints, the 

 apical joint rather large. Front femora with a complete row of spines on 

 the anterior margin beneath, 3-4 spines on the posterior margin ; mid- and 

 hind-femora with 6 spines on anterior margin, 5 on posterior margin, 



beneath. Formula of apical spines j, y, j ; genicular spines on all the 

 femora. 



Total length 13 mm. 



Distinguished by the great asynnnetry of the sub-genital lamina and by the 

 stout cerci.
