28 THE ENTOMOLOGIST S RECORD. 



(Uscipcnnis, Muls. and Rey, taken in the early part of this year from 

 moss in a small wood at Alphington, Devon. Teratological Specimens. 

 — Mr. J. R. le B. Tomlin exhibited a teratological specimen of the rare 

 beetle Triartliron iiioi'rkeli, swept in the Wellington College district 

 this summer. It has the last two joints of the left antenna completely 

 soldered together, making a two-jointed instead of a three-jointed club. 

 Also a specimen of Lonffitarsiix melanoceiihalitft (/) taken by Mr. J. 

 Collins at Oxford, with legs and tarsi remarkably thickened. Northern 

 Neuroptera. — Mr. W. J. Lucas exhibited five specimens, three J s 

 and two $ s of Panorpa (/ennanica, taken by Col. Yerbury, four at 

 Dingwall in May, and one at Lockinver in July. One J is practically 

 immaculate, and the other two nearly so ; the $ from Dingwall is 

 sparsely spotted, while the one from Lockinver is more nearly normal. 

 A Travelled Insect. — Mr. C. J. Gahan exhibited a living specimen 

 of Aapidonwrpha silacea. Boh., an African species of Cassididae, which 

 had been sent by Mr. G. St. John Mildmay from Nyali in British East 

 Africaon OctoberTth, reaching London on October 28th. Polyctenidae 

 VIVIPAROUS. — Dr. K. Jordan announced that the l'oli/ctenid(C which 

 are parasitic on bats in the tropics, are viviparous like the parasitic 

 Orthopteron Hetnivieridt. The young are born at a very advanced 

 stage, but yet differ considerably from the adult. Two of the forms 

 {iipa>i)iiae and talpa) described as distinct species, and lately placed in 

 two different genera, are immature and adult examples of the same 

 species. Rare British and Imported Colfoptera. — Mr. Harwood 

 exhibited two specimens of MicrKnda melanocephala taken near Bishop's 

 Stortford by sweeping in the evening, which he believed to be var. 

 brunnea, Heer. Also two specimens of (h-ypits vyanens taken by Mr. 

 W. H. Harwood at Colchester, one in May and the other in June of 

 this year, the first specimens taken in the district for nineteen years. 

 Also a species of L'occinella taken in a case of Tasmanian apples at 

 Colchester. African Species of Acr^a. — Mr. H. Eltringham 

 exhibited specimens of African Acrteas, to show that wide differences 

 of colour of pattern may occur in a single species, and conversely that 

 certain species which can scarcely be distinguished by their outward 

 appearance are nevertheless very distinct, as shown by the structure 

 of the male armature. Several new species and forms were also shown. 

 including A. lofiia, Eltr., ^ and 2 , A. grosreywri, Eltr., (^ , A. aureola 

 Eltr., (J, A. ella, Eltr., <? , A. cinerea subsp., alberta, Eltr., <? , A. 

 periphanes f. acritoides, Eltr., ^ , and A. astric/era f. brunnea, Eltr., <y 

 and $ . Dr. Jordan remarked on the extreme variability of the genus 

 and its allies, geographically, individually, and even in the characters 

 of the genitalia. Mr. Bethune-Baker remarked on the unreliability of 

 the genitalia in certain Lyctniida: The President stated that the <? 

 genitalia were, as a rule, reliable in the Aculeata, but in the Ten- 

 tlurdinidtr the ^ genitalia were quite useless for specific determination, 

 though the ? 's afford excellent characters. The Hon. Walter 

 Rothschild remarked on the identity of the ^ genitalia in certain 

 distinct species of Macroijlofiainae. Com. Walker read a paper on 

 " The Effect of Temperature on Animal (especially Insect) Life," by 

 A. G. Butler, Ph.D., F.L.S. The following papers were also com- 

 municated—" Parthenogenesis in Worker Ants, with special reference 

 to two colonies of Lasius nvjer, Linn.," by W. C. Crawley, B.A. " A 

 Monograph of the gefiuy Acraea," by H. Eltringham, M.A., F.Z.S.
