sino-le sclerite. In the males of the S]"»ecies under discussion, 

 however, it is completely separated in the mesial line into a right 

 and left lobe, which are very long and slender, projecting far 

 beyond the tenth tergite, and bearing numerous bristles on the 

 upper and lateral surfaces but none on the underside. 



Head. — The frontal tubercle is prominent. There is a row of 

 3 long bristles in front of the eye. The occiput bears one long 

 bristle above the antennal groove, besides the subapical row of 

 bristles. The bristles on the second segment of the antenna of 

 the 5 are long, there being at least five which reach beyond the 

 club. The rostrum extends to the base of the femur and the 

 maxillary palpi reach the trochanter. 



Thorax. — The comb of the prothorax consists of 17 or 18 spines, 

 there being usually an additional small spine on each side. The 

 meso- and metanotum have on the two sides together a posteiior 

 row of 12 bristles, and before it a row of about 6, the mesonotum 

 bearino- in addition a row of hairs at the base and several short 

 bristles on the back. The metanotum has four apical spines on 

 the two sides together. There are from 4 to 6 bristles on the 

 metepimerum (1 or 2, 2 or 3, 1), usually 4 or 5. 



Abdomen. — The tergites bear each two rows of bristles, the 

 first tergite having 2 or 3 additional bristles in front of the rows. 

 On none of the tergites does the anterior row extend down to the 

 most ventral bristle of the posterior row, the row stopping short 

 at the third or fourth bristle of the posterior row on the central 

 ssfments in the cJ , and at the second or third in the $ . 

 Tero-ites I to IV or Y bear apical spines like the metanotum, 

 the numbers being on the two sides together, 4 — 4 to 6—4 — 2 to 

 4 to 2. The S bears one long antepygidial bristle accom- 

 panied by two minute hairs, while the $ has 3 bristles (all 

 broken on both sides in our only $ ). The bristles on the 

 sternites number on the two sides together in the S 2, 6, 7, 8, 8, 

 8, and in the $ 5, 9, 11, 11, 11, 15, there being 16 additional 

 bristles on the seventh sternite of the $ , which are placed 

 irregularly in front of the row. The stigmata in the $ are placed 

 a little above the first bristle of the posterior row of the tergites 

 or on level with it, in the c? below it on the posterior segment. 



Legs. — The hind femur bears on the outer side one subapical 

 ventral bristle and in the anterior half one or three lateral ones. 

 On the inner surface there is a row of 9 to 12 bristles. The hind 

 tibia has outside a row of 8 or 9 lateral bristles and on the inside 

 a row of 4 to 7. The longest apical bristle of the second hind- 

 tarsal segment reaches beyond the apex of the third. The fourth 

 hind-tarsal segment is nearly twice as long as it is broad near the 



apex. 



Modified segments. — c? . The eighth tergite has 3 bristles below 

 the stigma, a row of 6 to 8 at the upper edge of the apical lobe, 

 with 1 or 2 bristles close to the row, and an oblique and more or 

 less irregular row of 5 or 6 near the ventral edge. The eighth 

 sternite (text-fig. 110, YIII. st.) is similar to that of C. lagomys.
