young animal creeps out, it moults, and loses this apparatus, wliicli is 

 another instance of a structure functioning only once in a life-time. 



Poliinating Capsid.* — 0. M. Renter describes Pamerldea rorklulm 

 g. et sp. n., a new Capsid for Cape Colony, which secures the pollination 

 of Rori/lula gorgonias. There are few Capsids that are of importance in 

 •connection with pollination, but this new form is well adapted for this 

 role. The whole body is hairy, and this is true also of the antenna, 

 the first two joints of the proboscis, and the very long legs. From a 

 taxonomic point of view the new Capsid is also interesting ; it is a type 

 of a new division (Pameridearia) of Capsids. 



Colour-Varieties of Nebalenia speciosa.f — F. Ris discusses some 

 of the colour-varieties of this smallest of European dragon-flies, and his 

 results, interesting in themselves, have particular importance, because 

 they do not bear out the conclusions which Darwin and MacLachlan 

 based on the facts known to them in this connection. 



Spermatogenesis of Forficula auricularia.J — H. Zweiger has 

 followed this out in considerable detail. The numl)er of chromosomes 

 is 26 : of these 6 are small, 2 medium, and IS large. The last are almost 

 ■alike in size, and in tlie first and second maturation spindles there are 

 3, 1, and t) respectively of these types. After several divisions the 

 spermatogonia pass into a growth stage, when the chromosomes are 

 equally distributed over the nucleus. Subsequently ensues a microsome 

 stage, when they are spread over the linin net, almost all taking part. 

 In cells with an accessory chromosome, three of the chromosomes retain 

 at this time their compact form, whilst in those without an accessory 

 chromosome only one retains its form. The maturation divisions are 

 described in detail. 



New Genus of Rhipiphorid8e.§ — Filippo Silvestri gives an account 

 ■of Rhgzodylops inquirendus g. et sp. n., and discusses its systematic 

 position. The female, egg, and first larva were fouiul on tufa ground 

 in Umbria, and the form is placed provisionally, until the male is 

 kuown, in the Rhipiphoridae. The anteinige and labial palps of the 

 female are rudimentary — the mouth, in fact, is reduced to a simple 

 apertui'e with two short lateral appendages. The tarsi are single 

 jointed. It appears to be intermediate between Rhipidkia and the 

 8tylopidge. 



Aquatic Cockroach. |1 — Nelson Annandale discusses a species of 

 Epilampra, living in an Indian jungle stream. The tip of the body is 

 held out of water, and the last spiracle is of a slightly tubular nature, 

 and projects at the side from below the posterior extremity of the 

 seventh tergite, being provided with a thick ring of chitin. The author 

 iilso notes that an aquatic glow-worm (Lampyrid) larva possesses a stai'-
