226 MECOPTERA FROM JAVA. 



as broad, B^d as long as broad and the following much 

 longer than broad ; 1^^ and 8^^ exceedingly long and slender, 

 9'h more or less pedunculate. 



In NeojMnorjxt the abdomen of the male is not longer 

 than the wings. The 5^^ abdominal segment as long as 

 broad ; 6tli and following ones longer than broad ; the length 

 of 7tl' and Sth a usual one; 9'-^ never pedunculate. 



The determination of Malayan species of P a n o r p i d a e is 

 a very difficult matter, because in the greater number of 

 species the wing-markings only are of little value, and 

 the constant and good characters found in the genitaliae 

 of the male, are scarcely visible in dried specimens. The 

 markings are very liable to vary, and a long series, f. 

 inst. of Neopanorpa angustipennis, from different localities 

 gives a good idea of the fact; therefore I think it may 

 be a useless work to describe Malayan species from the 

 female sex upon the wing-markings only, where they do 

 not differ very much from species known before. In the 

 European and Asiatic species the genital parts in the male 

 offer very good specific characters. In the Malayan species, 

 however, the lower appendages (genital valves of v. d. Weele) 

 are very stoutly built, thickened and somewhat swollen ; 

 they are almost similar in the different species, and in dried 

 specimens they are more or less shrivelled. Unfortunately 

 they also completely cover the penis-sheaths (titillators). The 

 upper appendage (prolongation of 9^^ tergit) is also very 

 similar in the different species, long and with rounded tip.

Museum of Leyden, July 1912, and later on Conservator R. van Ekcke, 

 Leyden, kindly has examined the type specimen and made a sketch of its 

 abdomen for me, so I am sure that the genus does not ditfer from the other 

 Panorpid-genera in this respect.
