The Pear-Borer.* * * § — M. Matsumara describes the adult and the life- 
history of Nephopteryx rubrizonella Bag., the larger pear-borer of Japan, 
which destroys 30-50 per cent, of the fruit every year. It was identified 
by Mr. W. J. Holland of Pittsburg, and belongs to the Microlepidoptera, 
group Pyradina, family Phycidse. The remedies are, pruning off the 
branches which bear eggs, the use of kerosene emulsion, and, as a last 
resource, pouring carbon bisulphide into the hole made in the fruit. 
j8. IMCyriopoda. 
A Mysterious Myriopod.f — M. H. W. Brolemann refers under this 
title to Scolopendra ( Scolopendropsis ) bahiensis Brandt, 1841, the only 
Scolopendra with 23 segments and possessed of ocelli. No one seems 
to have observed it since Brandt received it from Bahia in 1840, until 
Brolemann recently found a specimen in a collection made by M. 
Gounelle in 1889, in the environs of Bahia. He gives a description 
of the external characters, and refers, as Pocock has done, to the extra- 
ordinary resemblance between it and Pithoptus calcar atus Pocock. One 
slight difference is that the armature of the tarsi in P. calcaratus is 
absent in Scolopendropsis bahiensis ; but Pocock’s P. inermis , also with- 
out armature, seems to show that the difference referred to is unim- 
portant. There remains the fact that Brandt’s species has 23 segments, 
while Pocock’s has 21, but it may be that the individuals with 23 seg- 
ments simply express dimorphism or some peculiarity of development. 
Oviparity of Scolopendra.J — Sig. Filippo Silvestri has observed 
the female of Scolopendra cingulata Latr., guarding its eggs, which it 
does most assiduously, and has thus disproved the statement of Gervais 
and Lucas, not to speak of many text-books, that these Myriopods are 
viviparous. The eggs had a pale-yellow colour and an elliptical form. 
It is possible that the mistake arose as an erroneous inference from the 
way in which the mother animal guards its young ones. 
Morphology and Classification of Diplopoda.§ — Dr. C. Verhoeff 
concludes his prolonged series of studies on Diplopoda. This part 
deals with (a) Chordeumidae (including descriptions of two new genera* 
Heterobraueria and Bielzia, and several new species), and ( b ) Iulidee 
(including the new genus Stenophyllum , and several new species). 
S. Araclmida. 
Development of Phrynidae.|| — Mdlle. S. Pereyaslawzewa has studied 
the first stages in the development of Tarantula palmata Herbst, Phrynus 
niedius Herbst, and Pliryniscus bacillifer Gerstaecker. 
(1) In the first form the spherical ova showed a white spot covering 
about a third of the surface. Sections demonstrated this to be a blasto- 
derm, with the three embryonic layers, and with the rudiments of 
thoracic limbs and nervous system. 
(2) In the second form the blastoderm surrounded the whole egg ;
