joints of the fi'ont tarsi of the male are, however, shininsj black, much 

 more curved and ciliated, and with a rather lont? curved apical bristle 

 on the under- side of each of them. One male was taken by Col. 

 Yerbury at Porthcawl on July 9th, 1906. 



The opportunity may be taken here of statin^ that D. strigipes, 

 Verr., is not uncommon on the marsliy sides of the Suffolk rivers near 

 Woodbridge and Orford in Suffolk. 



38. PiTecUohothrns comitiaUs, Kow. : Many years ago I introduced 

 P. ducalis, Lw., as British from a number of specimens taken l\y me 

 at Seaford, in Sussex, but it was not until 1907 that I recognised the 

 true P. ducaUs in a long series taken by Col. Yerbury at Walton-on- 

 Naze, in August. The two species are very closely allied, but P. comi- 

 tiaJis has the antennre on the underside at the base more extensively 

 orange, and the wings less conspicuously darkened on the fore part.. 

 I suspect that another British species of Peecilobothrus occurs at 

 Walton-on-Naze, and possibly still another at Grravesend, but if so, 

 they are closely allied, and I want to see more specimens.

A NEW AFRICAN FLEA. 

 BY JAMES WATERSTON, B.D., B. Sc. 



Ctenophthalmtjs calceatus, sp. nov. 



Belonging to the section of the genus characterised by having 

 a pronotal comb of sixteen teeth and three genal spines. Closely 

 related to Ct. triodonhis, Eothsch. (Novit. ZooL, vol. xiv, March, 1907, 

 pp. 330-331, figs. 3 and 4), from which it differs in the following 

 details : — 



Thorax. — The met. epim. bears 7 hairs (1. 3. 3.). 



Abdomen. — Besides the normal two rows of bristles on tergites 1-7, there is 

 a third on tergites 1 and 2, and traces of the same on 3, 4, and 7 



Legs. — 3rd segment of fore tarsus, and 4th segment of hind tarsus, much 

 longer than broad. 



Modified segments ? . — 7th st. with moderately deep sinus dividing the 



sternite into an angulated upper and a rounded lower lobe. Post median row 



of 5 long bristles and an anterior parallel row of shorter ones. 8th tergite with 



4 bristles above stigma, 3 short bristles at lower ventral angle, and one or two 



others on the ventral aspect disposed as in the figui-e. One or two short stout 



bristles on the inner surface near ventral angle. Apparently the tergite has 



the edge naked from this point to the stigma, but the specimen is not perfect 



in this region.
