comparison could be made when the material was carefully 

 mounted. Specimens in the Hope Department identical with 

 No. 1 had been named by Bourgeois L. (M.) scapularis, Murray, 

 but they were certainly different from the unique female type 

 of this species in the British Museum, and the President con- 

 sidered them to be Bourgeois' jemoralis. No. 6 was similarly 

 identical with specimens named by Bourgeois L. (M.) dentipes, 

 Dal., var. flavoscapularis, Bourg., but the President considered 

 that dentipes was a synonym of rostratus, L. Species 4 and 5 

 were closely similar; but the male genitalia of No. 4 resembled 

 those of specimens in the British Museum from Abyssinia, the 

 locality from which Guerin described trabeatus, and the 

 President had therefore considered No. 4 to be true trabeatus. 



The whole assemblage presented an extraordinarily uniform 

 appearance, the only marked difierence, on superficial examina- 

 tion, being in the degree to which sexual dimorphism was 

 carried. In species No. 1 the elytra of the males were unex- 

 panded and female-like, while there was not much difference 

 in this respect between the sexes of Nos. 7 and 9. In Nos. 4 

 and 5 the males were dimorphic, the elytra of some being 

 female-like and of others highly expanded and of a peculiar 

 shape, similar in both forms. In all the other species the 

 males possessed the usual broad elytra, of a very uniform 

 shape, but differing widely from those of the females. The 

 relative numbers of the sexes varied in the different species 

 in an extremely interesting way. 



Judging from this experience L. (M.) Jemoralis and L. duvi- 

 vieri were the two dominant species in the locality at the 

 time when the series was collected.

 Aug. 22, 1917, was read by Prof. Poulton, who exhibited the

 by Mr. Rowland E. Turner as the var. sepulchralis, Sm., of 

 the above-named very variable species.
