( 6-tfi ) 



the apical margin there is a row of about eight, gradually decreasing in length, 

 the upper one being the longest, and towards the base there are three long ones 

 preceded by two short ones. On the innersidc the tergite bears a great number of 

 hairs at the apex. The eighth sternite bears a few bristles at the apex (PI. XIV. 

 fig. 76, viii. St.). 



Length, 3-7 mm. (measured on the slide, the abdomen being rather extended). 



This species agrees with C. trichosa in many respects, but differs in the details 

 given in the description. 



Our examples of this species are as follows : — 



2 ? ? , Japan, Mustela itatsi (Pryer). 



34. Ctenopsyllus granti* spec. nov. (PI. XV. fig. U. 87 ; XVII. fig. 91). 



Hea/d. — The eye is situated near the npper end of the antenual groove. The 

 anterior part of the head ^inclines backwards as in C. muticali (PI. XV. fig. 84, tJ). 

 Parallel with the frontal edge there is a row of bristles, and halfway to the 

 antennal groove a vertical row of five spines, of which the third is very long and 

 pointed. On the posterior part there are a number of very heavy bristles on the 

 back, one above the antennal groove and one near the apex being es|)ecially long. 

 This last bristle is the longest. It belongs to the subapical row, and stands widely 

 apart from the next long bristle of this row. Along the antennal groove there is 

 a row of seven (t?) or four (?) hairs. The hairs on the second antennal segment 

 are short. The rostrum is very little longer than the maxillary palpus. The labial 

 palpus consists of four segments, of which the last is about twice as long as broad. 

 The fourth segment of the maxillary palpus is as long as the second. 



Thorax. — The pronotum is much longer above than at the side, being produced 

 backwards above. It bears a comb of tliirteen long teeth in the S and of seventeen 

 in the ? . The teeth do not stand close together. In front of the comb there is 

 a row of four bristles with minute hairs in between, there being on the back one 

 more bristle before the middle. The mesonotum bears two rows of bristles and a 

 few hairs on the back. There is also one short subapical spine on each side near 

 the ventral edge. Tiie metanotnm is much longer than the mesonotum, and bears 

 two rows of bristles. There are two short stout a])ical spines on each side of the 

 metanotum and the first and second abdominal tergites, and one spine on the third 

 fergite. The epimerum of the metathorax is strongly rounded in the middle of 

 the apical margin, and bears four bristles (2.2). 



Abdomen. — The abdominal tergites bear one row of bristles (about five on each 

 side), the first tergite possessing in addition a few hairs before the middle. The 

 stigma is placed within this row, and stands either above or below the first bristle 

 present. The seventh tergite bears one long bristle, accompanied on each side by 

 a short hair. The first five sternites bear in the i one bristle, in the ? two, with 

 the exception of the first, which has only one. On the seventh sternite there are 

 two bristles in the S and three in the ?. This sternite is deeply sinuate in the ? 

 (PI. XVI. fig. 91, vii. St.). 



Legs. — The bristles on the coxae are few in number. The hindcoxa bears on 

 the iunerside four or five short spines and posteriorly at the apex two bristles. 

 The mid- and hindfemora have on the outerside two subapical ventral hairs, and on 



• This species is named in honour of Mr. C. J. B. Grant.
