pronotnm is longer than in the species mentioned, particularly the comb, which 

 contains thirty-five spines. The mesoplenra bear 20 (19) bristles, the metepimernm 

 has 26 (25), the basal abdominal steniite 13 (13), the seventh tergite ou the two sides 

 together a row of nine long bristles, and in front of the row tweuty-oue additiimal 

 bristles, the numbers on the seventh sternite beuig thirteen and forty-eight, and the 

 eighth tergite has on each side six bristles above the stigma and thirty-one to thirty- 

 seven below it. The three combs of the abdomen contain 4, 4, 6(4, 2, 6) spines. 

 The numbers in brackets refer to the other side. The stylet is half as long again as 

 in I), apistiis and h/pasus, being as long as in the much larger D. /ursutus and 

 equalling twice the distance between the first and second bristles of the posterior

 oblique than in the allied species, the sinus being shallow and the upper lobe 

 less prominent.

i. A single specimen oi Dinoptii/llus was fonnd by Mr. Kemp on Graphiurits 

 viicrotus satyratus. This example, though closely agreeing with I), li/pusiis in other 

 respects, is remarkable for its short round frons, which is more like that of a 

 lypvsus ? than a cf. In this character 1). kempi comes very near to D. ellobius 

 Eoths. (1904). The vestigial tubercle is exactly in the centre of the frons (text- 

 fig. 40). The genal {)rocess is longer and broader than in D. apistus, li/pusiis, 

 and ellobius, and the second genal spine (counted from below) slenderer.
