length III' the (itlicr two. The seventh sternitr (I'l. IX. fiy;. (i) is ])nxhiceil into 

 a pointed hihe, as sliown in the lignre. 



Legs. — The hindl'einiir lias a row of .^ hrislh's lui the insich", ami the hiiultiliia 

 about 18 bristles on tiie onter snrl'ace exclusive of I In' bristles situated at the 

 ape.x, the inside bearing a row of 8 or bristles. 



J/()f////(v/ S,i/iHC///x. — The eighth tergite (I'l. IX. fig. (ij bears about L'n long 

 and 14 shorter bristles on the outer surface, 3 or 4 long ones being plaeed beneath 

 tlie stigma. The stylet is shorter tbau iu (jallinae, the two lateral bristles being 

 placed a very little beyond half-way between the base and the apex. 



One ? oft' }fiis(iia cniiiiieii, collected by von FriUienfehl, j)robably in the 

 neighbourhood of Vieniia. Tlie occurrence of this insect on Mastela is doubtless 

 accidental, as the species is a true bird-lh 



lea. 



4. Ceratophylliis phaulius sjiec. nov. (I'l. IX. fig. 8). 



Likewise a bird-flea. There is iu tlie collection only one very pale and 

 apparently imiuutnre ¥, which moreover is imperfect. The specimen exhibits 

 some interesting distinctions, and we therefore do not hesitate to describe it. 



Head. — The frous bears two rows of bristles. The posterior row, which is 

 placed in front of the eye, contains 3 bristles, of which the central one is the 

 shortest, while the anterior row consists of 5 short thin bristles. The occiput 

 has no bristle behind the liase of the anteunal groove, but one long one and a 

 short one above the centre of the groove. The long ventral bristle of the sub- 

 ajiical row is separated from the bristle situated above it by a wide interspace. 

 Below this ventral bristle there is a short slender one. 



Thorax. — The pronotal comb consists of 28 sjiines. 



Abdomen. — The first and fourth tergite bear on each side 2 slender pale 

 apical sjiines. There are 3 antepygidial bristles on the seventh tergite, the 

 middle one being long and the other two very short. The basal steruite has one 

 ventral bristle on each side, the following three sternites bearing 3 bristles, and 

 the sternite of the sixth segment 4 or 5 on each side. The steruite of the seventh 

 segment has the apical edge unfortunately torn on both sides, so that it is im- 

 possible to describe (he outline. This sternite bears a row of about bristles, 

 and in front of the row about 7 more bristles on each side. 



Ler/s. — The liindfemur bears a row of (J bristles on tlie inside ai.d one subbasal 

 and one subapical bristle on the outside. 



Modified Sei/ment-i.—TUhe eighth tergite (PI. IX. fig. 8) bears 4 long bristles 

 at the apical margin and about IU moderately long and 12 short ones on the lower 

 portion of the outer suif'ace, there being also several bristles below the stigma 

 (not shown in tlie figure). Inside the eighth tergite lies the ninth sternite, which 

 in this sjiecies bears more bristles at its edge than in any other sjiecies we are 

 acquainted wilh (cf. fig. S, ix. st). 



We have one ? fnuiid in the nest of Cotile ri/xtria at Stockerau, Lower 

 Austria, by Herr Beriiliauer. There was also a ? of Cerafo/>/ii/l//is dalei in the 

 same tube, and the occurrence ou Cotile is no doubt accidental. 



5. Ceratophyllus frontalis spec. nov. (I'l. IX. figs. 1 — 5). 

 A very dark sjiecies, wliich is unlike any other descriiied Ce.nttojjiii/lliix. 

 Head. — The frons bears a very strong tubercle in botii sexes (PI. IX. figs. 1, 2) 

 and two rows of bristles as shown in the figure. The occijiut has three rows of
