on the authority of specimens captured by the late Dr, Capron, 
and by Commander Walker in the Chatham district, and it has 
been recently taken by Dr. Sharp in the New Forest. It 
appears to be rare on the Continent. 
TERATOLOGICAL Specimens.—Mr. J. R. Le B. Tomiiy ex- 
hibited a teratological specimen of the rare beetle 7'riarthron 
maerkeli, swept in the Wellington College district, Berks, this 
summer. It has the last two joints of left antenna completely 
soldered together, making a two-jointed instead of a three- 
jointed club. Also a specimen of Longitarsus melanocephalus (?) 
taken by Mr. J. Collins at Oxford, with legs and tarsi 
remarkably thickened. 
Nortaern Nevroptera.—Mr. W. J. Lucas exhibited five 
specimens, three ¢ ¢ and two? 2? of Panorpa germanica, taken 
by Col. Yerbury, four at Dingwall in May, and one at Lock- 
inver in July. One ¢ is practically immaculate, and the 
other two nearly so; the 9 from Dingwall is sparsely spotted, 
while the one from Lockinver is more nearly normal. Five 
normal specimens from Surrey and Hants were shown for 
comparison. 
A TrRavetLeD Insect.—Mr. C. J. GAnan exhibited a living 
specimen of Aspidomorpha silacea, Boh., an African species 
of Cassididae, which had been sent by Mr. G. St. John Mild- 
may from Nyali in British East Africa on October 7th, 
1eaching London on October 28th. 
POLYCTENIDAE VivipaARous.—Dr. K. Jorpan, who has lately 
been engaged on an examination of the specimens of Poly- 
ctenidae contained in the collection of the British Museum, 
announced that these insects, which are parasitic on bats in 
the tropics, are viviparous like the parasitic Orthopteron 
Hemimerus. The young are born at a very advanced stage, 
but yet differ considerably from the adult. Two of the forms 
(spasmae and tulpa) described as distinct species, and lately 
placed in two different genera, are immature and adult 
examples of the same species. 
Dr. CuapMAN remarked upon certain supposed instances of 
viviparous butterflies, saying that the idea originated in a 
mistake, the eggs having been ready to be laid at the time 
of the parents’ death.
