New species of Blattidae in the collection of the 
Deutsche Entomologische National-Museum. (Orthopt.) 
By R. Shelford, M. A., F.L.S. (Oxford). 
< (Plate IL) 
I am indebted to Mr. Sigm. Schenkling for the oppor- 
tunity of examining a small collection of Blattidae in the Deutsche 
Entomologische National-Museum. The following species ') appear 
to be undescribed previously. 
Genus Anaplecta Burm. 
Anaplecta conradti sp. n. (Plate II, fig. 1). 
¢. 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 séctors, which on the right tegmen join distally. 
Wings infuscated, martinal 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, 1* 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. 
1 g, Kamerun (Conradt). 
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. Miller 
of Greifswald I have been able to examine several of the types of 
1) Except where otherwise stated the types are in the Deutsche 
Entomologische National-Museum.
