GENERA OF AFRICAN LYCAENIDAE 279 



R3_5 arise from upper angle of cell, close to or connate with (occasionally long stalked 



with Mi) 2 



2 Male with coremata (as above) ......... Iridanini 



No coremata ............ Liptenini 



The presence of coremata in many species has been well known to me for many 

 years. I make no mention of them in the present work for the following reasons : — 



(1) Within a single genus there may be some species with coremata, others without. 



(2) In the course of dissection in water, after maceration in potash, it often happens 

 that, on applying pressure to the abdomen to force the extrusion of the genitalia, 

 the coremata remain within the eighth segment, and escape detection through 

 being mixed up with other abdominal debris. This depends I believe, in some 

 degree upon the degree of decomposition sustained by the organs after death, 

 in a hot and humid climate, and also perhaps upon the strength of the potash 

 solution used. 



(3) In the process of mounting in Canada balsam, when pressure is put upon the 

 cover slip, the coremata often break away from the vinculum and the scales are 

 dispersed throughout the preparation and become almost invisible ; for this 

 reason I have hitherto not included the coremata in my preparations. 



These technical details may seem trivial, and out of place. Forty years experience, 

 however, has taught me that they are of importance. It is only too easy to draw 

 false conclusions from a faulty mount. 



Wishing to check the taxonomic importance of the coremata, in the sense in which 

 Clench uses them, I have made a small series of fresh preparations of species already 

 examined, paying particular attention to preserving the coremata, with the following 

 results.
