76 ENTOMOLOGISK TIDSKRIFT 1S94. 



is seen without dissection, but I do not dare to give any inter- 

 pretation. 



As mentioned before the loth segment is provided with 

 ccrci. These are essentially uniform in both sexes, but perhaps 

 a little longer in the female; in the figured female each is 4,9 ™'" 

 long, in the male but 4,5 '""\ From a point near the basis they 

 decrease evenly in thickness towards the acute tip, and they are 

 inarticulate, somewhat depressed and upon and near the lateral 

 margins provided with numerous, shorter, stift' setK. 



f. The clothing of the body etc. Jn the male the posterior 

 portion of the lateral margin and the exterior portion of the 

 posterior margin of the 3 thoracal tergites are furnished with a 

 row of middle-long setas, being shorter anteriorly on the lateral 

 margin and towards the middle line on the posterior margin; the 

 hind margin of the 9 anterior abdominal tergites and 7 anterior 

 sternites are towards the lateral corners furnished with similar 

 setœ. On the superior hind margin of the head is also found some 

 similar setœ towards the lateral corner. Further the upper side 

 of the body with exception of the head and the 1 1 th abdominal 

 segment is rather closely set with exceedingly short, depressed 

 hairs (»le corps est ... . revêtu d'un duvet de poils courts et 

 couchés, plus ou moins clairsemés» [Saussure, oj). cit. p. 12]) 

 which rather easily are rubbed off. The head of my specimen 

 is destitute of such hairs, but if it also will be the case in fresh 

 specimens I do not venture to say. 



In the two examined females the seta; along the lateral and 

 hind margins of the thoracal and abdominal segments are about 

 half as long as in the male, and almost all the minute hairs on 

 the surface have disappeared, but the tergites are everywhere finely 

 punctuated, these punctuations being marks of former hairs. Fig. 

 I (PI. 2) shows the female as I found it almost without hairs. 

 The male measures 11,9 '"'", the female 11,5 "i"' without the cerci. 



g. Colour. In the female the whole body, the antennse and 

 the cerci are of a uniform, tawny colour, the legs perhaps a little 

 lighter, more yellowish; the male is a little more reddish brown, 

 with the process from the sternite of the 9th segment and the 

 genital hooks dark brown. 



h. The spiracles. None of these, with exception of the
