BLATTIDJi: PRESERVED IN AMBER, FROM PRUSSIA. 349 



anterior margin and none on posterior margin beneath, the right hind-femur 

 entirely unarmed. Formula o£ apical spines a, ^ , ; no genicular spines on 



front femora. 



Total length 8 mm. 



I know of no modern representative of the genus with so sparse a femoral 

 armature. The apex of the abdomen is obscured by some foreign body, so 

 that it is not possible to examine the cerci or the supra-anal lamina. 



Ceratinoptera klebsi, sp. n. 



? . No. 6131. 



Testaceous, with a piceous pattern on the pronotum and the veins of the 

 tegmina piceous, Pronotum trapezoidal, posteriorly truncate. Tegmina 

 lanceolate, not extending beyond the 5th abdominal segment ; mediastinal 

 area large, marginal area broad, 4-5 costals, 3 longitudinal discoidal sectors, 

 anal vein well marked, 3 axillaries. Supra-anal lamina produced, angles 

 rounded, surpassed by the sub-genital lamina, which is large and sub- 

 cucullate. Cerci moderate, with 7 visible joints. Front femora on anterior 

 margin beneath with 4 strong spines, succeeded distally by minute piliform 



spines ; remaining femora strongly armed. Formula of apical spines y, y, r 



Total length 8"1 mm. ; length of tegmina 4 mm. ; pronotum 2'3 mm. x 

 2'6 mm. 



The unique specimen is in a bad state of preservation, but in size it is 

 intermediate between the other species of the genus, and is readily distin- 

 guishable from them by its coloration and maidvings. 



Temnopteryx klebsi, sp. n. 



S. No. 5^^i/. ? ?. Nos. 5449, ^7/0. 



Castaneous. Antenna longer than the body. Vertex of head not covered 

 by pronotum. Pronotum trapezoidal, posteriorly truncate, exposing the 

 large scutellum in the (^, lateral margins paler than the disc. Tegmina 

 quadrate, not extending beyond the middle of the first abdominal tergite, 

 their sutural margins touching, outer and inner posterior angles rounded, 

 marginal field broader and paler than disc, venation obsolete, anal vein not 

 visible. Abdomen in the ^ not tapering, the last 4 segments somewhat 

 constricted, supra-anal lamina trigonal, apex sub-truncate, sub-genital lamina 

 produced and slightly asymmetrical with two (?) blunt styles. Abdomen of 

 the ? ovate, supra-anal lamina trigonal, sub-genital lamina produced, ample. 

 Cerci rather blunt, with 9 visible joints. Front femora with a complete row 

 of strong spines on anterior margin, 3 spines in the disial half of the posterior 

 margin, beneath ; mid- and hind-femora with 6 spines on anterior margin,
