8. Oeratophyllus euteles, sp. n. (Text-fig. 116.) 



2 . This is one of the species in which the first pair of bristles 

 of the fifth segment of all the tarsi is shifted on to the ventral 

 surface, being placed almost in between the second pair. The 

 species may be recognised by the absence of bristles from the first 

 abdominal sternite, the shortness of the bristles on the tarsi, the 

 paucity of bristles on the femora, &c. 



Head. — The frontal tubercle is placed nearer to the central 

 sensory organ (pale dot) than to the oral angle. The eye is well 

 developed and pigmented. There is a row of three long bristles 

 before the eye, the uppermost bristle being a little lower than the 

 centre of the eye. In front of this bristle there are one or two 

 small bristles and usually a third further upwards nearer the 

 antennal groove. The occiput bears a large bristle above the centre 

 of the antennal groove, a small bristle further frontad and another 

 small, one further dorsad. The subapical row of bristles of the 

 occiput consists on each side of 6 bristles, of which the ventral one 

 is large. The interspace between this bristle and the next is twice 

 the size of the interspace between the second and third bristles of 

 that row. Five of the bristles of the second antennal segment a,re 

 prolonged, two of them nearly reaching to the apex of the club. 

 The rostrum extends to the apex of the coxa, its fifth segment 

 being more than twice the length of the fourth. The maxillary 

 palpus reaches to the apex of the fourth segment of the rostrum, 

 the proportional lengths of its segments being 17, 15, 12, 19. 



Thorax. — The pronotal comb consists of 18 spines. The meso- 

 and metanotum bear each two rows of bristles and a few additional 

 dorsal bristles representing a third row. The mesopleura have 8 

 bristles and some additional short stout hairs. The metepimerum 

 bears 6 bristles (2, 3, 1). The metanotum has one apical spine on 

 each side. 



Abdomen.— The tergites bear each two rows of bristles as 

 follows (the first number being that of the anterior row) : 8 or 9, 

 9_8 to 10, 12—8 to 10, 12—7 to 9, 12 or 13—5 or 9, 12 or 13— 

 5 or 8, 11 or 12 — 3 or 4, 9 or 10, The first sternite has no bristles 

 at all. The sternites of segments III to YI have on each side 

 three bristles, and that of segment YII bears four bristles 

 with an additional bristle in front of the row. There are three 

 antepygidial bristles, the middle one being twice the length of the 

 upper and one-fifth longer than the lower. 



Legs. — The fore femur has two bristles on the outer surface, and 

 one on the inner, apart from a ventral subapical bristle. The mid 

 and hind femora have only the subapical ventral bristle on the 

 outside, and on the inside a small lateral bristle and a small ven- 

 tral suba,pical one. The hind tibia has a row of 8 lateral bristles 

 on the outside and two or three bristles on the inner. The first 

 and second hind-tarsal segments are long and slender and the 

 bristles of the tarsi short. The longest apical bristle of the second 

 hind-tarsal segment is one-third shorter than the third segment. 

 The fifth segment is rather short in all the tarsi and bears
