since been shown by Dr. R. 0. L. Porkins that the mouth- 

 parts of Ischnoccelia are quite distinct from those of EJhnus, 

 a character which was overlooked at the time. The genera 

 may be separated as follows : — 



Ischnoccelia. 



Both maxillary and labial palpi 

 3-jointed ; maxillary palpi very 

 short, hardly as long as joint 2 of 

 the labial palpi. 



JElimus. 



Maxillary palpi 6-jointed, labial 

 palpi 4-jointed. 



The two species described {I. c. pp. 38 & 40) as Elimus 

 ferrugh^eus and E. rohiisfus are both referable to IscImocoeHa, 

 of which /. xanthochroma, Perk. (Proc. Haiwai. Ent. Soc. 



p. 32, 1908), is the type species. 

 M.-Waldo, remains in Elimus. 



Elimus mackayensis^ 



RhaphidoglOSSA, S. S. Saunders. 



RliapMdoglossa jlavo-ornata^ Cam . 



Rhaphiglossa flavo-ornata, Cam. Trans. S. Afr. Philosoph. Soc. vol. xv.

My species, described from the male, is certainly synony- 

 mous with B. flavo-ornata. Cam., of which species I have 

 received a pair from Dr. Brauns, of Willowmore. It was 

 suggested (/. c. p. 35) that R. punctata might be the male of 

 R. natalensis, Sm., which species is exceedingly closely 

 related to R. flavo-ornata, but may be distinguished from it 

 by the subtubercular process in the middle of the anterior 

 margin of the clypeus, which is not present in any specimen 

 of i?. flavo-ornata which has been examined. The yellow 

 band at the base of the clypeus of R. flavo-ornata is wanting 

 in Smith's type. 



Dr. 11. Brauns has bred this species commonly in South 

 Africa, and has communicated some interesting facts con- 

 cerning its life-history. The species excavates its cells in 

 dry stems with a soft pulp, chiefly Liliacese, and makes 

 simple partitions, provisioning its larvae with small larv?e of 

 Lepidoptera. The larvte remain sometimes, when adult, two 

 or three years motionless without pupating. The imagines 

 do not leave the stem in the ordinary way, but each one 

 perforates its cell sideways.
