modified Segments. — ?. The seveuth sternite (PI. YIl. fig. 19) is bisinnate, 

 the npper sinivs being broad and shallow, the lower being small. The eighth 

 tergite bears a few hairs above the stigma, and two long and two short ones below 

 it. The bristles on the lower part of the segment are situated as shown in the 

 figure. The stylet is very long and cnrvod. Tlie anal tergite liears two bristles at 

 the corner below tlie insertion of the stylet. 



Length : ? , 4 mm. 



This species is easily recognised by the characteristic, stylet, the armature of 

 tlie abdominal tergites, and the shape of the seventh sternite. The heiid and tarsi 

 also readily distinguish this insect. 



We have one example of this insect from Quosnel, B. 0., November ~'ud, I'.'UO, 

 from Scinropterm sabrinus, collected by Mr. G. F. Dip pic. 



14. Ceratophyllus lucifer spec. nov. (PI. VI. fig. 12). 



Only the frmale is known. 



Head. — The frontal tubercle is small. The second of the three eye-bristles 

 stands closer to the uppermost than to the ventral one. On the occiput there is a 

 bristle behind the base of the antennal groove and another before the middle with 

 a smaller one above it. The subapical row is complete, the second bristle being 

 equidistant from the first and third. The long ventral bristle of this row is ac- 

 companied by three bristles, one standing in front of it, another below it, and ^ 

 third minute one above it. The rostrum reaches a little beyond the ape.x of the 

 foreco.xa. 



Thorax. — The pronotum bears a comb of nineteen to twenty spines. On the 

 mesonotnm there are two rows of bristles, besides a great number of small hairs, 

 which stand on the back and at the base. It bears, moreover, five slender subapical 

 spines on each side. The mesosternum bears about ten hairs, which are mostly 

 minute, and the epimerum of the mesothorax six or seven bristles. The metanotum 

 bears three rows of bristles, the first row not reaching halfway down the side. It 

 possesses also two ajiical spines on each side. On the epimerum of the metathorax 

 there are eight bristles (3.4.1.). 



Abdomen. — The first tergite bears three rows of bristles, the other tergites two, 

 all having in addition two or three hairs on the back. There are three apical 

 bristles on the seventh tergite, the first and third being about half the length of the 

 second or a little less. The first sternite bears one ventral bristle on each side, the 

 following four sternites possessing a row of four or five bristles with a few hairs in 

 front. The seventh sternite bears five long bristles and about eighteen shorter ones. 

 This segment is deeply sinuate (PI. VI. fig. 12). 



Iiegs. — The hindfemur bears on the inner side a row of four bristles, besides the 

 subapical bristle. On the outer side of the hindtibia there are two lateral rows of 

 bristles, and on the inner side a row of from four to six. The first three hindtarsal 

 segments bear two almost regular rows of bristles on the ventral surface. The 

 longest apical bristle of the second hindtarsal segment does not reach the apex of 

 the third segment, while the longest apical bristle of the third segment reaches 

 just beyond the apex of the fourth. The latter segment is about twice as long as 

 it is wide at the apex. The first lateral pair of bristles of the segment is on the fore- 

 and midtarsus distinctly dislocated towards the middle, while on the hin<ltarsus it is 

 as iMucli lateral as the third pair,
