LXV. — On Coleoptera from Aden and Somaliland. By G. J. 

 Gahan, M.A., of the British Museum (Natural History). 



The following paper contains an account of two separate 

 collections of Coleoptera — one made by Lieut.-Colonel Yerbury, 

 E.A., at Aden and the surrounding district, the other by 

 Mr. E. Lort Phillips in Somaliland. These collections have 

 been presented to the Trustees of the British Museum, and 

 comprise a number of interesting species, which, in addition 

 to those described as new, had not previously been represented 

 in the National Collection. In deference to the wishes of 

 the donors, and in view of the faunistically interesting nature 

 of the localities, I have endeavoured to make the lists of 

 species as complete as possible. One genus and species of 

 Buprestidse from Aden and a few species of other families 

 still remain undetermined ; but even with those omitted the 

 list of species from Aden &c. will show that Lieut.-Colonel 

 Yerbury's collection is one of the largest yet made in that 

 locality.
