view), and bears at the apical edge some extremely tine and sliort hairs. The 

 stylet is abunt tliree times as long as it is basally broad. The aual t-.teniite liears 

 on each side two long apical bristles and some stout ventral ones, besides 

 numerous thin hairs. 



Length: cJ, 3-2 mm. ; ?,3-Gmm. 



We have one pair of this species from Bukit Besar, 2500 ft., State of 

 Nawngchik, Eastern Malay States, May loth, 1901, from Sciunis nigrovittatus, 

 kindly sent to us by Mr. H. Robinson. 



4. Ceratophyllus robinsoni spec. uov. (PL XIII. fig. 6). 



? . Allied to C. ahalae Eothsch., but differs in the following characters : — 



Head. — The frontal part of the head bears a few less bristles. The subapical 

 row of bristles of the occiput is widely interrupted, the second bristle of that row 

 not being developed. The rostrum reaches to the apex of the forecoxa. 



Thorax. — Tlie pronotnm bears a comb of twenty teeth. The metanotum has 

 three rows of bristles, and in front of them some dorsal bristles representing a 

 fourth row. 



Abdomen. — There are two long apical bristles on the seventh tergite, placed 

 on a double cone. Below them there is a third bristle, not situated on a cone. 

 Tergites 2 to 7 bear on each side one rather long black apical spine, and tergite 5 

 one spine on one side only. The basal sternite bears about ten short hairs laterally 

 near the base iind three bristles at the ventral edge, the posterior bristle being the 

 longest. The sternites of segments 3 to 6 have a row of four long bristles and 

 eleven to fifteen shorter bristles in front of the row, the bristles being still more 

 numerous on the seventh segment. The seventh sternite bears a deep and narrow 

 sinus (PI. XIII. fig. 6, vii. st.). The stigmata stand in front of the middle row of 

 bristles. They are situated on a level with the third long bristle of the jiosterior 

 row or above the second bristle, except on the second and seventh tergite, where 

 the posterior row of bristles extends less far downwards. 



Legs.— [The first foPetarsal segment is shorter than the second. The lateral 

 bristles of the fifth segment are thinner than in C. ahalae, and there are only 

 two short spine-like bristles ventrally at the apex of the fifth fore- and midtarsal 

 segments instead of four. 



The measurements of the tarsi are as follows : 



Uodified Segments. — The eighth tergite (PI. XIII. fig. 6, vii. t.) bears a few 

 short hairs above the stigma and none below it. The ventral apical angle is produced. 

 Above this projection there are two pairs of bristles, and farther back about fourfeen 

 more bristles. Tiie eighth sternite bears a lew minute jiairs at the apex. The 

 stylet is slightly conical, being about four times as long as it is broad. It l)ears 

 one long bristle at the ajiex accompanied by two very minute hairs. Tiiere i.s one 

 liristle at the corner of the tergite, beneath the stylet. The aual sternite bears lony 

 bristles only, nine in numlier.
