of " dry-season " forms. Tho largo proportion of Pierines 

 to the whole numbci' is remarkable ; as also is the general 

 resemblance borne by the whole assemblage to the butter- 

 fly fauna of Aden.- It was remarked by Dr. Butler in 

 Proc. Zool. Soc, 1001, p. 25, that the collection made by 

 Captain Dunn on the Bahr-el-Zcraf (White Nile) had a 

 very Aden-like aspect, and in particular that it contained 

 all the forms of Limnas ehrysipims, Linn., just as they occur 

 at Aden. In Somaliland, as is well known, the prevailing 

 form of L. clirijm'p'p'us is L. Idugii, Butl., with a sprinkling of 

 its modification L. durqypus, Klug ; in other respects the 

 present collection recalls the Somaliland fauna almost as 

 distinctly as it docs that of Aden. 



It will be noticed that Mr. Boat's insect-collecting was 

 limited to a very few occasions, and to only three months 

 in the year. This will no doubt account for the absence 

 from his collection of a few species which occur in that of 

 Captain Dunn {loc. cit.). Among such are Precis hoopis, 

 Trim., Afclla p)haIantI(a,Dvury, and especially H)jiJolimnas 

 misi2)2nis, Linn. There is no new species among Mr. Loat's 

 captures, but they include the male of Finacoptcryx 

 vcnatus, Butl., of which tlie female only has hitherto been 

 known to science. 



Subjoined is an account of the places and dates of 

 capture, as carefully recorded by Mr. Boat, together with a 

 list of the specimens taken on each occasion. It has been 

 thought worth while to preserve his details, even to the 

 time of day at which the captures were made.

 T. aniigone group. It is barely, if at all, distinguishable 

 from T. evagore, Klug (2". saxcus, Swinh.). See below, p. 161.
