OENERIC SEPARATION OF " GNOPHOS " OBFUSCATA FROM GLAUCINARIA. 121 



1. POLYPHAGA ^GYPTIACA, Linil. 



Length of body, 20mm. ^ . 27mm. -88mm. 5 ; of elytra, 2J:mm. 

 S . 0mm. ? . 



Rare in western Europe ; recorded from Calabria and Sicily. 



2. PoLYPHAOA LiviDA, Brunuer. 



Length of body, 11mm. S- 16mm. $ ; of elytra, 17mm. <J , 

 0mm. ? . 



A Levantine species, but taken m Spain by Sanchez Gomez at 

 Cartagena, and by Bosca in the Isal Mayor del Mar menor. (Several 

 allied species occur on the other parts of the coast of the 

 Mediterranean.) 



In addition to the forms enumerated above, a number of exotic 

 cockroaches have occurred in Europe at various times, without actually 

 becoming established. Several representatives of the Panchloridae 

 have been recorded. In this family the femora are unarmed, and the 

 tarsi have a pad between the claws. Rhi/parobia maderae, Fabr., 

 occurs fairly often in the London docks and at Covent Garden ; it is 

 also noted by Seoane from the arsenal at Ferrol. The allied Leiiro- 

 phaea sio-inaiitcnsis, L., is recorded from Andalusia, and also from 

 Bognor. Species of the genus PancJdora, which contains a number of 

 pale green medium-sized cockroaches, have straggled to Europe from 

 South America on more than one occasion ; indeed, they are fairly 

 frequent at Liverpool. P. exuleta is recorded from Scotland and South 

 Leverton. Sanphoeta hiclttata, Burni., is probaljly the insect recorded 

 under the name of Blatta (jalUca from Paris by Fabricius. The 

 Blaberidae have the femora unarmed, and no pad between the claws 

 of the tarsi. They are extremely large insects, usually of pale straw- 

 colour. Several species are known to have occurred in Europe, 

 imported from South America and the \Yest Indies. Other recorded 

 exotic cockroaches are Peiisphaerii.t ^^tylifcra, Burm., recorded by 

 Fischer from Tuscany; T^aratropa elefians, Burm., taken at Ferrol; 

 and Stylopyya decorato, Brunner, taken at Worksop.

The generic separation of " Gnophos " obfuscata from glaucinaria. 



By LOUIS B. PKOUT, F.E.S. 

 1 was interested in reading Mr. Tutt's notes on the eggs of these 

 two species (Ent. Fiec, xv., pp. 238-289) and his deduction therefrom. 

 I am unfortunately grossly ignorant of the early stages of the various 

 members of the " genus " Unuplws, but I should like to point out that 

 Mr. Tutt's conclusion is only what would be expected. Every 

 systematist has made some separation of its species into genera, with 

 the exception of a few of the most extreme " lumpers " (Lederer, etc.), 

 and even they have divided the genus into sections ; and whatever 

 has been the exact basis of the erection of outlying genera, it has 

 always happened that dbfuscata, Schiff. {inyytillata, Thnb., Stgr. Cat.), 

 has fallen into one of these, whilst ulancinaria, Hb., has fallen into 

 another. Thus, Hiibner {clrc. 1825) erects Catascia for obfuscata, 

 Schiff., ojjeraria, Hb., and dilticidaria, Schiff., and Hyposcutis for 

 ulancinaria, Hb., and uniridaria, Hb. Boisduval (1840) leaves 

 (jlaucinaria in (Jnnphus, and makes obfuscata an aberrant Klophso — a
