7. Ceratophyllus quirini spec. nov. (PL VI. fig. 1). 



In the S of this sjjecies— we do not know the ?— the first midtarsal segment 

 is long, and hairy as in eumolpi. 



Head. — The head is similar to that of emnolpi, but the anterior row of bristles 

 on the frontal part is represented only by some minnte hairs. The hair at the 

 posterior ventral corner of the occiput standing below the long ventral bristle of 

 the snbapical row is short. The rostrum is also shorter than in emnolpi. 



Thorax. — The hairs in front of the two rows of bristles on the meso- and 

 metanotum are fewer in number than in eumolpi. The mesonotnm bears two or 

 three hair-like snbapical spines on each side. The sternum of the mesothorax has 

 only two or three small hairs. The snbapical bristle of the metathoracical episternum 

 is absent (in our only specimen). 



Abdomen. — The anterior row of bristles of the tergites contains fewer bristles 

 than in numolpi, the row not extending down to the stigma. The lateral bristles 

 are widely separate and minute. The spines on the first three tergites are two, one, 

 and one on each side. On the seventh tergite the dorsal bristles of the posterior 

 row stand close together, and are nearer the apex of the segment than is usually 

 the case. The long apical bristle is accomjmnied by one minute hair standing 

 above it. There are no bristles on the first two sternites, but some minute pale 

 dots — the jioints of insertion of extremely small hairs — similar dots being found 

 also on the other sternites. The sternites of segments 4 to 6 bear one bristle, 

 while that of the seventh segment bears one or two bristles, with one hair placed 

 in front. 



Legs The furefemur has about six small hairs on the outer side. On the 



hindfemur there is no lateral hair on the outer side, while on the inner side there is 

 one near the base, fullowed by one or two short ones further back. The mid- and 

 hindtibiae bear two rows of bristles on the outer side, the hindtibia having on the 

 inner surface a row of three or four. The third dorsal pair of bristles of the 

 hindtibia is re])resented by two small hairs. The first midtarsal segment bears 

 several long thin bristles on the hinder side, the longest ajiical bristle extending 

 beyond the middle of the third segment. The bristles of the second segment are 

 normal, the longest apical one reaching only beyond the middle of the fourth 

 segment. The hindtarsus is similar to that of eumolpi, but the longest apical 

 bristle of the anterior side is shorter. The measurements of the mid- and hindtarsi 

 are as follows : — 



Modified Segments. — i. The eighth tergite does not bear any bristles, except 

 some short ones behind and below the stigma and two long ones near the ventral 

 margin. The eighth sternite is similar to that of eumolpi, but is rather wider at 

 the apex. It bears two very long bristles at the apex, one on each side, and several 

 short hairs in front of them. The manubrium of the clasper is obtuse. The 

 process of the clasper is longer and slenderer than in eumolpi (PL VI. fig. 1). The 

 finger is peculiar in shape, being long, with the distal margin angnlate below the
