384 DR. K, JORDAN AND HON. X. C. ROTHSCUILD ON 



The apical margin of tliis tergite is gently incurved, its upper 

 angle being rounded, and the lower one projecting and being 

 almost pointed. The ninth sternite (IX. st.) bears one short but 

 rather stout biistle at its lower corner. The receptaculum seminis 

 has an elongate head, which is longer than the tail. 



Length (mounted specimens) 2"4 to 27 mm. 



Three females from 23 miles S.E. of Ta-tsien-lu, 7500 ft., off 

 Sciarotmnias davidianus consohririMs M.-Edw. ; Omi-shan, Sze- 

 chuen, 9500 ft., off the same host and off' Twmioi^s sivinhoei 

 M.-Edw. 



9. Ceratopiiyllus ph.<eopis, sp. n. (Text-fig. 117.) 



2 . This species, of which we have only one female, is easily 

 recognised by the very feebly pigmented eye, the very short bristles 

 of the antenna, and the deeply sinuate seventh abdominal sternite. 



Head. — The frons is very slanting. The frontal tubercle stands 

 about ha]f-\vay between the oral corner and the central sensory 

 organ (pale spot), the distance from the tubercle to the oral angle 

 being about equal to the diameter of the eye. There are three 

 long bristles in front of the eye, the uppermost being placed near 

 the antennal groove, the interspace between this bristle and the 

 second being nearly twice as large as the intei'space bertween the 

 second and third bristles. In front of the lower bristle there is 

 one small bristle, several minute hairs being placed in between the 

 two other bristles. The occiput bears one bristle above the 

 antennal groove, arid a subapical row of 5 (on each side), the most 

 ventral of them being long and sti'ong. The bristles of the second 

 segment of the antenna are quite minute. The rostrum reaches 

 to the apex of the coxa, the last segment being half as long 

 ag-ain as the fourth. The eye is feebly pigmented, excepting 

 the anterior and posterior edges. It appears deeply excised at a 

 certain focus. 



Thorax. — The comb of the pronotum consists of 18 spines, the 

 most ventral one of one side being veiy small. The meso- a,nd 

 metanota bear each two rows of bristles. The mesopleura have 5 

 or 6 bristles and the metepimerum 8 (4, 3, 1). The metanotum 

 has also 2 apical spines on each side. 



Abdomen. — The tergites bear tw'o rows of bristles, the anterior 

 row containing but a small number of them, the numbers in the 

 two rows being 7 and 14 on the fourth tergite on the two sides 

 together. The stigmata are placed dorsally to and in front of the 

 ventral bristle of the second row. There are three antepygidial 

 bristles, the lower one being but little shorter than the central 

 bristle, while the upper one is about one-third the length of the 

 latter. The basal steinite has on each side a patch of four lateral 

 bristles and ventrally one bristle. The numbers of bristles of the 

 sternites of segments III to VII are on the two sides together 

 (the first number giving the bristles placed in front of the row) 4, 

 11 — 3, 11 — 2, 8 — 0, 10. Tergites I and II bear an apical spine 

 on each side.
