New species of Blattidae in the collection of the 



Deutsche Entomologische National-Museum. (Orthopt.) 



By R. Shelford, M. A., F. L. S. (Oxford). 



(Plate II.) 



I am indebted fco Mr. Sigm. Schenkung for the oppor- 

 tunity of exarnining a small collection of Blattidae in the Deutsche 

 Entomologische National-Museum. The following species J ) appear 

 to be undescribed previously. 



(remis Anaplecta Burm. 

 Anaple cta conradti sp. n. (Plate II, fig. 1). 



<J. Flavo-testaceous , disc of pronotum with two broad lon- 

 gitudinal castaneous vittae, lateral margins broadly hyaline. Tegmina 

 with 10 costals, joined by transverse venulae, discoidal field with 

 2 longitudinal sectors, which on the right tegmen join distally. 

 Wings infuscated, marginal field dilated, 7 costal veins, radial vein 

 strongly flexuose, median vein slender, straight ; medio-discal 

 area twice as broad as medio-ulnar and crossed by one trans- 

 verse nervule, l st axillary vein tri-ramose ; apical area parabolic, 

 two-fifths of total wing-length, its base not obtusely angled, its 

 apex not emarginate. Antepenultimate and penultimate abdominal 

 tergites narrow and transverse, their posterior margins widely 

 emarginate ; supra-anal lamina trigonal, on each side an incrassated 

 carina, these carinae converge posteriorly and define a depression 

 at the bottom of which is situated the scent-gland opening, 

 marked by two tufts of hair. Cerci long, testaceous. 



Total length 6,5 mm ; length of tegmina 5 mm.

The wing-venation in the African Anaplectae is very uniform 

 and affords few characters for purposes of specific diagnosis ; the 

 above described species should be readily recognisable by its colour- 

 ation and by the form of the secondary sexual apparatus of the 

 male, a character which has hitherto not been shown to occur 

 in any other species of the genus. 



Genus Ischnoptera Burm. 



Thanks to the kindness of Professor Dr. G. W. M ü 1 1 e r 

 of Greifswald I have been able to examine several of the types of 



J ) Except where otherwise stated the types are in the Deutsche 

 Entomologische National-Museum.
