27. Ctenophthalmus lycosius spec. nov. (text-figs. 25 and 26). 



c? ? . A species remarkable for the peculiar shape of the male genitalia. Ii> 

 the nnmber and arrangement of the bristles, apart from the modified segments, thi& 

 species agrees almost exactly with Ct. acanthurus, engis, and others. The genal 

 spines are pointed. The genal process in the c? is a little broader than the second 

 genal spine, and in the ? half as broad again. The lobe of the pronotnm situated 

 below the comb is broader than in the allied species, its vertical diameter being 

 eqnal to the distance from the lower edge of the first spine in the J to the upper 

 edge of the third, and in the J nearly to the centre of the fonrth spine. The second 

 hindtarsal segment bears an apical bristle which reaches beyond the third segment, 

 and another which extends to the apex of that segment. The mesopleura of the 

 ? bear eight or nine bristles. 



Modified Segments. — <S. The eighth abdominal sternite bears on each side: 



Fig. 25. — Ctenophthalmva lyconvs, 



about nine bristles, of which the three distal ones are the longest. The clasper 

 (C), text-fig. 25) terminates in an almost square process (P) which is ronnded- 

 trnncate distally, the apical margin being divided by a very small sinns into a short 

 upper and a longer lower portion. Above this sinns there are about eight bristles 

 arranged in a donble row, the outer row being continued ventrad by three long 

 bristles, of which the last is placed near the ventral margin. The movable process 

 F is distally dilated both dorsally and ventrally, resembling a hammer. There are 

 four long bristles at the truncate ventral angle of F, while the strongly rounded 

 dorsal margin bears a row of spiuiform bristles, a few similar bristles, variable in.
