124 THE entomologist's record. 



elongated. The other hiudwing and the wings on the upperside were 

 normal. Mammoth Scale Insect of Rhodesia. — Mr. C. 0. Waterhouse 

 sent for exhibition living 3 s and immature 2 s of the Mammoth 

 Scale Insect which infests the M'sasa tree in Rhodesia. Also a dead 

 example of the fully grown 2 scale. These were recently received 

 from Mr. -J. Cameron of the Department of Agriculture, of Rhodesia. 

 The g s were in abundance in white cocoons among dead leaves under 

 the trees. They are what are known in collections under the generic 

 name Mdnn/ildafbus. The 2 has been named l.nphococcus inaxi>iius by 

 Mr. Lounsbury. Coleopteka and Hemiptera new to Britain. — Mr. E. 

 A. Butler exhibited one species of Coleoptera, and five of Hemiptera 

 recently added to the British fauna, n't., (a) Myrmecopora brevipea, 

 Butl., from Tintagel, Cornwall, a species allied to M. Kvida, Er. ; {b) 

 Cyintin obliqiius. Horv., from Ashburnham, Sussex, in the Hastings' 

 district, a species allied to ( '. (jlandicolor, Hahn. ; (c) Empoasca biitlerj, 

 Edw., and H. populi, Edw., the former from dwarf sallows on the 

 sandhills of Carmarthenshire, and the latter from Lombardy poplars, 

 Highgate; and (d) on behalf of Mr. Jas. Edwards, Tijpfdocyba 

 frustrator, Edw., and T. fratercula, Edw. (together with a sketch of 

 the appendages of the a>da?agus in each case), both from Colesborne, 

 Gloucestershire. These two species were described by Mr. Edwards 

 in April 1908, but by an oversight they were omitted from the new 

 catalogue of British Hemiptera which has recently been published. 

 Mr. Butler also showed the unique example of Mynifmniris yracilu, 

 Sahib., taken by him at Fleet, Hants, in August 1903. Polymorphic 

 Papilios and Styx infernalih.^ — Dr. K. Jordan exhibited the polymorphic 

 Papilio lysithdKK and P. hectorides from Brazil, and the models which 

 they injitate. The exhibit illustrated a phenomenon observed in 

 various groups of butterflies, r/c, that a mimetic species may be broken 

 up into a number of very different-looking individual varieties, which 

 are all specifically the same, while the imitated models are specifically 

 distinct from one another. He also exhibited both sexes of the 

 peculiar Peruvian butterfly, Styx infernalia, described by Staudinger as 

 a Pierid. Dr. Schatz made a mistake in describing the foretarsus of 

 the g as being fully developed. The distal segments of this tarsus 

 are more or less completely fused, and the claws are absent. The 

 insect is decidedly an Erycinid in the structure of the antenna, thorax, 

 legs, neuration and the egg. Mimetic Locust. — Di-. .Jordan also 

 showed, on behalf of the Hon. N. Charles Rothschild, an Acrotylu& 

 which the latter observed in some numbers in the desert on the 

 Upper Nile. The colour of these small locusts so closely agrees with 

 that of the sand and the pebbles (also exhibited) that, when settled, 

 the insects disappear entirely from view. A]>ril 1th, 1909. — Ova of 

 Tapinostola fulva. — Mr. H. M. Edelsten exhibited ova of Tapinoatola 

 fidia (ill situ) laid within the curled leaf of ('are.c pahtdnsa. Also a 

 photograph of the anal segments of the 2 showing the spinal 

 appendages from the ventral side. These, when not in use, are 

 carried Hat, as in the photograph, but when the 2 is going to lay, 

 they are folded together and thrust between the curled edges of a leaf 

 to force it apart ; the fold makes a hollow in which the ova are 

 deposited ; and the leaf closes over the ova when the appendages are 

 withdrawn.
