examples. It would be interesting to investigate whether 

 the male claspers of arthechippus bore any resemblance to 

 those of obsoleta. It was not to be wondered at that a hybrid 

 combining the features of arthemis and archippus should 

 approach in certain respects an ancestral species intermediate 

 between the two, but the resemblance did not warrant the 

 conclusion that obsoleta originated as a hybrid. Such a view 

 was opposed by its geographical distribution, as also by the 

 results hitherto obtained from the pairing of archippus and 

 arthemis — offspring of a single sex not yet known to pair with 

 any allied female. 



A Colour-Association of Mylabris (Coleoptera) from 

 S. Nigeria, by K. G. Blair and Prof. E. B. Poulton. — 

 Prof. Poulton said that he had received a fine series of 

 Mylabrid beetles, including many pairs in coitu, collected by 

 Mr. C. 0. Farquharson from " ground-nut," Arachis hypogaea, 

 L. (Leguminosae, Tribe Hedysareae), at Moor Plantation (480- 

 580 ft.), 4 miles west of Ibadan, S. Nigeria. The conditions 

 under which the beetles occurred were described in the 

 following extracts from Mr. Farquharson's letters : — 



"May 28, 1915. 

 " I forgot another item of news. I have a very special 

 experiment with ground-nuts in hand just now, and a wretched 

 beetle has arrived in considerable numbers to eat the flowers. 

 Dr. Lamborn got it last year on bush hosts, and it turned out 

 to be Decatoma * ajfinis, Oliv. [also other species] and D. affinis 

 var. culternauti. [This first determination of the var. proved 

 to be erroneous.] On comparing his types there seems to me 

 to be more in it than that. I am to send you a series, which 

 may interest you. I may say that the entomologist is on 

 active service on the frontier, hence my dabbling with beetles 

 on ground-nuts. 



"May 31, 1916. 

 " I added a few more to the Decatoma series on Saturday, 

 but I am in hopes that I may get a few more pairs in coitu, 

 which should make the series more valuable.
