was pointed out by the Rev. K. St. Aubyn Rogers in Trans. 

 Ent. Soc, 1908, p. 540. The following specimens captured 

 at Taveta, on May 10, L905, by .Air. Rogers are in the bionomic 

 series of the Hope Department: — B. severina, 2; Teracolus 

 halimede, King. 2 ; T. celimene, Lucas, 2, and A. levubu, £. 

 Mr. Rogers considers that at Taveta B. mesentina forms, 

 with severina, a centre for the convergence of other Pierines, 

 and he writes of the above list, to which mesentina might be 

 added, l " all these species bear a considerable resemblance on 

 the wing, and all settle in exactly the same way with wings 

 half rai ;ed. 1 think Teracolus castalis, Stand., might be 

 added to the assemblage. . . . The Hesperid is of great 

 interest, as mimicry in tin.; group is so rare. The species 

 has a rapid flight as is usual in this family, but its compara- 

 tively large size and it ! conspicuous black-and-white colouring 

 mark it out at once from its congeners and give it a strong 

 superficial resemblance to the forms mentioned above 

 {ibid., p. 510). 



The specimens captured at mud on Jan. 18, 1917, may be 

 compared with 18 male Pierines settled on a patch of cowdung 

 and all under the net together, on Aug. 25 at Itigi in the 

 dry season (from about May 25) : — 8 Belenois mesentina, Cr., 

 5 B. severina, Cr., 2 Pinacopteryx si maun. Hopff., 1 Teracolus 

 cris. Klug, 1 Herpaenia eriphia>, Godt., 1 Glutophrissa 

 epaphia, Cr. 



Returning to the letter of March 12 : — 



"On -bin. 2'.) 1 got two Lycaenids new to me, I think 

 [Epamera aphnneoides, Trim., and Argiolaus silarus, II. II. 

 Druce]. Also on Feb. 5. one do. do. [Castalius hintza, Trim.]. 

 Pinacopteryx simana is very abundant at Itigi [see Dr. 

 F. A. Dixey in Trans. Ent. Soc. L918, p. 191]. By the way, 

 the Mud-drinker's aposeme is scarce hereabouts, and I think 

 there are only Mylothris agathina, Cr. (commonest), and one 

 Phrissura. | In relation to this subject Capt. Carpenter wrote 

 on Nov. 2. 1917, of the Lycaenid Phylaria cyara, Hew., '* I 

 have never seen it except drinking at mud." See Proc. Ent 

 Soc. 1915, pp. Ixvi, Ixxi. lxxvi-lxxix.] Belenois is not 

 common: indeed Teracoli are the most abundant; but even 

 now Itigi is a poor place for butterflies.
