16 THE entomologist's RECORD. 



I find the egg of A. fiava is exceeding^ variable in size, and besides 

 being oval in transverse section, is not fiat beneath, but nearly as 

 rounded as above. My measurements of A. fiava eggs show: length,, 

 0-65mm.-0-90mm. ; width, 0-G0ram.-0-72mm. ; height, 0-45mm.- 

 0-54mm. Comparing these with Mr, Sich's measiu'ements {Brit. 

 Lep., viii., p. 108), and with Mr. Hellins' statement, no doubt a rough 

 one, that the egg is half as long again as wide, I think we may 

 assume that Mr. Sich's measurements possibly erred somewhat, and 

 mine much more, owing to our method of obtaining the eggs not 

 presenting them, as they occur when laid naturally, after more drying 

 and shrinking has taken place. To bring out these points in com- 

 parison with the eggs of Cijclopides, I have made rough outlines (?f the 

 eggs of the three species. See Fig. 1 (preceding page). 



To return to Cyclopides. The Cyclopidid eggs, as shewn in the 

 diagram above, have the oval outline of Thymelicine eggs so much 

 less pronounced than in Adopaea, that it appears hitherto to have 

 escaped notice, but is, when once seen, quite obvious. This fact makes 

 it probable that Cijclopides is much more closely related to ThyinelicuN 

 than one gathers from the discussion of the subject in Tutt's British 

 Lepidoptera, vol. viii.., p. 91. It is, however, quite rational to hold, 

 that this form of egg exists in the two groups independently, although it 

 certainly seems unlikely, considering the very special nature of the egg.

The Conocephalidae.* 



By MALCOLM BUEE, F.L.S., F.Z.S., F.E.S., etc. 



This is a very useful work from the pen of Dr. H. Karny. It is a^ 

 supplement to Professor J. Eedtenbacher's Monograph published in 

 ihe same pages in 1891. During the sixteen years which have elapsed 

 since the appearance of Professor Eedtenbacher's able monograph of 

 the Cnnocepludidae, considerable progress has been made in our know- 

 ledge of ."this family. This progress has been epitomised by Herr 

 Karny of Vienna. This zealous and prolific 'orthopterist has also 

 characterised and described seventeen new genera and 95 new species, 

 and so this revision is amply justified by abundance of new material. 



The family is divided into four tribes : The Conocephalini, At/raecini, 

 Xiphidiini and Litroscelini. 



The tribe Conocephalini includes 37 genera, of which four are new, 

 and seventeen new species are described. The typical genus, Cono- 

 rephalns, ceases to have an independent existence, as Eedtenbacher's 

 three subdivisions are given names, namely Neoconocephalm, Encono- 

 cephalus and Hovwrocoryphus, but as the latter includes the type species 

 the name cannot stand : Cnnocephabis must prevail, and the subgenera 

 must be genera, as there can be no rank intermediate between genus 

 and species. It is fortunate that this unwieldy genus has been sub- 

 divided, for Xeoco7iocejihaliis alone contains no fewer than 78 species, of 

 which nineteen are new ; the type is N. subidatiis,Jio\. EHconoccphalnny 

 formed for C. acu-ndnata, Fabr., has five new species, and Homorocoryphus, 

 or as we prefer Conocephaliis, has 43 species, by which twelve are 

 described for the first time ; our old friend Conocephaliis mandihidaris,
