2. Acropsylla episema sp. nuv. 



? . A pale species, of which we have only the ? . 



Head. — The frons is prodaced into a kind of snout at a short distance from 

 the maxillary palpi (Fig. 2). The two genal spines are placed apart from each 

 other and are both rounded at tlie apex. There are sixteen long bristles on 

 the frons (8, 3, 3, 2), the last two being the longest, and also a number of 

 small hairs. Below the eye there are two pale dots, whose position is not 

 the same on the two sides of the head ; another jmir is placed near the 

 genal edge. There are two sensory organs (pale spots) on each side of the 

 anterior part of the frons. The occiput has three rows of bristles. The first 

 and second segments of the maxillary palpus are nearly the same in length, 

 the third is much shorter, while the fourth is longer. The rostrum reaches to 

 three-fourtlis of the forecoxa. The first segment of tlie labial paljjna is longer 

 than the fourth and shorter than the fifth, whereas the second and third 

 together are but little longer tlian the fourth. The first segment of the 

 antenna is short ; the bristles of the second segment are (jnite short, being not 

 longer than those of the first. 



Thorax. — The pronotal comb consists of eighteen spines, besides a small sp'ne 

 on each side. The mesonotum bears three rows of bristles, besides numerous 

 short ones whirli are placed at and near the base, there being on each side also 

 three or four sj)iiies on the inside before the apex. The mesopleura bear about 

 eleven bristles. The metanotum has likewise three rows of bristles, but those in 

 the anterior row are less numerous than on the mesonotum. The episternum of 

 the metathorax has two or three bristles, the sternum one large one (aceompanied liy 

 a small bristle on one side of the body in our only specimen), and the epimenini 

 nine (=4, 4, 1). The metanotum, moreover, has a comb of eight short, stout, 

 dark-brown spines. 



Abdomen. — There are two rows of bristles on the tergites, the anterior row 

 being represented by four bristles on tergite VI and by two on VII. The 

 stigmata are phu'ed aliove the first bristle on the anterior tergites, and below it on 

 the posterior ones. The jjostmedian row of tergite VI contains ten bristles on the 

 two sides together. Of the three autepygidial bristles the middle one is nearly 

 twice the length of the lower bristle and five times as long as the upper one. The 

 bristles on tlie sternites number on the two sides together 2, 4, 4, .5, .*), 8. 



Legs. — The forecoxa has more than sixty bristles. There are about twelve 

 bristles on the outer surface of the forefemur, apart from the two snbapical ventral 

 ones. The mid- and hindfemora have a few lateral bristles near the apex, the 

 hindfemur also bearing one lateral bristle near the base. Both these femora iiave 

 two ventral snbapical bristles on the outer surface and one on the inner. The 

 dorsal bristles of the tibiae do not form a comb. The mid- and hindtibiae have 

 eight dorsal notches, the third and sixth of which bear only one bristle on 

 the midtibia, and the sixtli one on the hindtibia. The outer surface of the 

 midtibia has about fifteen and that of the hindtibia about twenty bristles, besides 

 a number of bristles placed at and near the anterior edge. The midtibia has two 

 or three bristles on the inner surface, and the hindtibia fonr or five. The bristles 

 of the tarsi are numerous but short ; none of the bristles reach to the apex of the 

 next segment. The fifth segment bears ventrally at the apex two bristles, which
