33. Chaetopsylla mikado spec nov. (PI. XIV. fig. 76). 



Head.— The anterior part of the head bears a series of four bristles iu front 

 of and close to the eje, and obli(|uely above the eye a row of four short hairs, of 

 which the two lower ones are stout, while the other two are thin. On the hinder 

 part iif the head there are three bristles behind the base of the antennal groove, 

 followed by another row of three. The bristles of the subapical row stand rather 

 close together, there being about nine on each side. There are no short hairs 

 above the antennal groove except at the apex. The bristles of the second antennal 

 segment are shorter than the club. The labial palpi reach to the end of the 

 forecoxa, and consist of six segments, of which the last is about twice the length 

 of the penultimate one. 



Thorax. — Tiie pronotum bears one row of bristles. On the mesonotum there 

 are two rows of bristles, with a few additional hairs anteriorly on the back, and 

 there are also four long slender subapical spines on each side. The metanotnm, 

 which is much longer than the mesonotum, bears two rows of bristles and an 

 abbreviated row in front of them on the back. The epimerum of the metathorax 

 bears two vertical rows of bristles, the first row containing nine or ten, the 

 second six. 



Abdomen — The first and second abdominal tergites bear two rows of bristles, 

 with one or two additional ones. On the five following tergites both rows are 

 very much reduced, the anterior row consisting of three (occasionally two) 

 bristles on each side, standing above the stigma, and the posterior row consisting 

 of six bristles on the third tergite and of four or three on the other tergites. On 

 the second tergite there is below the stigma a patch of seven or eight bristles 

 arranged in two rows corresponding to the rows of bristles situated farther towards 

 the back. The first sternite bears a ventral bristle and four to six small hairs 

 near the upper edge. The other sternites have a subapical series of four to six 

 bristles, precedetl by some short hairs on sternites 3 to 6. 



Legs. — The bristles of the forecoxa are very much shorter than those of 

 €. trickosa. There are two slender bristles posteriorly at the apex of the hind- 

 coxa. The midfemur has on the outerside a series of eight bristles, and on the 

 innerside two ventral subapical ones. On the hindfemur there are on the outer- 

 side twelve to fifteen bristles arranged in a row, and on the innerside four or five 

 situated in the posterior half. The tibiae bear one somewhat irregular row of 

 hairs on the outerside, and a number of ventral and subventral hairs, which are 

 very much shorter and thinner. The measurements of the tarsi are as follows : — 



Modified Segments.— The eighth tergite (Pi. XIV. fig. 76) bears about five 

 hairs above the stigma, and from the stigma downwards a regular series. At
