Head. — The frons is mnch more convex in the c? tbau in the ?, and bears in 

 both sexes a row of three bristles in front of the e3'e. The npper one of these 

 bristles is placed about on a level with the centre of the e3-e, .and is long ; the second 

 bristle is mnch smaller, while the third is about as large as the first. In the c? 

 there are two more bristles above the first e3'e-bristle, both being thinner and shorter , 

 than the second auteocular bristle. The occiput bears one median bristle above the 

 anteunal groove, no bristle behind that groove, and a subapical row of five. The 

 ventral bristle of this row is very long and accompanied below by an additional 

 bristle, which is in the cJ as small as the small hairs placed along the antennal 

 groove, whereas it has in the ? the size of the upper subapical bristles. There is 

 a wide gap between the long subapical bristle and the oue above it. The rostrum 

 reaches to the trochanter. 



Thorax. — The pronotum bears a row of thirteen or fourteen bristles on the two 

 sides together, the ventral bristle being very long and the two dorsal ones slightly 

 more jiroximal in position than the others, particularly in the i , which sex, more- 

 over, has two or three small dorsal bristles in front of the row. The comb contains 

 nineteen to twenty-two spines and an additional small spine on each side. All the 

 Bpines end in a sharp point. The mesonotum has two rows of bristles and a number 

 of dorsal bristles from the anterior row to the base, as well as a row of minute hairs 

 along the basal edge. In the c? the dorsal bristles of the meso- and metanutnm, 

 and of the first and second abdominal tergites are semi-erect, and, being more 

 numerous and longer than is usual in Ceratophi/lli, represent a mane (PI. VII. rig. 4). 

 The small hairs near the anterior edge of the mesopleura are numerous, the cJ bear- 

 ing about a dozen or more and the ? usually more than eighteen. The mesonotum 

 lias about a dozen setiform subapical spines on the inside and the metanotum four 

 or five short, thick apical spines, on the two sides together. The metepimerum has 

 five to seven bristles (2 or 3, 2 or 3, 1). 



Abdomen. — The first three or four tergites bear a few short apical spines, and 

 tergites i. to vi. are dorsally minutely dentate. The first tergite has two complete 

 rows of bristles, and in the i some additional dorsal bristles. On the tergites 

 iii. to vii. the anterior row is much reduced in both sexes, but especially so in 

 the (?. The stigmata are placed some distance in front of the ventral bristle of the 

 posterior row. The <S has two antepygidial bristles on a rather strongly produced 

 cone, the upper bristle being short and obtuse and the lower one long. In the ? 

 there are three antepygidial bristles, of which the dorsal oue is two-fifths and the 

 ventral one five-sixths the length of the central bristle. The sternites of segments 

 iii. to vi. bear on the two sides together eight or nine bristles in the <S and on an 

 average eighteen in the ¥. 



Legs. — All the femora have a single subapical ventral bristle on the outside, 

 the fore-femur in addition a numberof small hairs on the lateral outer surface, while 

 the mid- and hind-femora bear a row of bristles on the inside. This row contains 

 on the hind-femur six to nine bristles, apart from the subapical ventral one. The 

 hind-tibia has a row of four to six lateral bristles on the inside, and a row of five to 

 seven (inclusive of the apical one) on the outside. One apical bristle of the first 

 hind-tarsal segment reaches to the apex of the second segment, one of the second 

 segment to the apex of the fourth segment and another beyond it. The proximal 

 pair of bristles of the fifth tarsal segment is distinctly moved on to the ventral 

 surface, but is situated proximally to the second pair, not in between it. The 

 relative lengths of the mid- and hind-tarsal segments are as follows : —
