110 THE entomologist's RECORD. 



sometimes surmounted by a small gland ; lo (nervure) sometimes anasto- 

 mosing with 12, often connected with 9, ii out of 10 towards or above 

 middle, or \i lower anastomosing with 12, or often absent." Now by 

 this arrangement and under this diagnosis Mr. Meyrick classifies 

 brunneata {pinetaria), vauaria iivavaria), rohoraria and coUiOrtaria as 

 belonging to this genus. Fancy, tvavaria and roboraria, pifiefaria and 

 consortaria in one genus ! This is, of course, due to the ors above, 

 which, I should think, might have been multiplied by Mr. Meyrick 

 with a little skill so as to include the whole European fauna in one 

 genus. By means of similars " ors " luteolata {cratcBgata) is included 

 in the same genus with notata, littirata, altertiata and claihrata, whilst 

 fasciaria, margarifata, pulveraria and dolobraria get united in Metro- 

 campa with an exceptionally good supply of "^ ors." The " ors " in 

 Hydriomena allow the inclusion of the following British species : — 

 ocellala, sif/iit/ata variata, juniperata, sagittata, fiilvata, dofata, picatn, 

 ??iiata, site/ata, sordidata, trifasciata, truncata, iminanata, silaceatn, 

 coryldta, suffumata, ccEsiata,fiaviciiiciata, dubitata, badiata, nigrofasciaria, 

 mbidata, berberata, cucullata, albiciilata, adcequata, utiangidata, minor- 

 ata, tcBfiiatn, uni/asciata, alchemillata, affinitata, decoiorata, alhilata, 

 procellata, bilineata, flicviata, polygram fnata, lapidata ; rather a strange 

 mixture those who know the larvae and pupre will probably think. 

 There is still another important point. The usage of these "ors" 

 sometimes admits almost anything, and their application allows species 

 to go in several genera. Take for example, Hydriomena and Xanthorhoe. 

 The only positive difference in these genera appears to be "Antennae 

 in $ ciliated, rarely dentate or naked" in Hydriomena, and " Antennas 

 in 1^ bipectinated, apex usually simple " in Xanf/iorlwe ; but the latter 

 character, I should say, is almost included in the " ciliated " of the 

 former species. As a result of this fine distinction, the species are 

 separated in a marvellous manner. Variata gets into Hydriomena, 

 firmata into Xanthorhoe ; nnangulata in the former, montanata and 

 fluctuata in the latter, polygrammata and lapidata in Hydriomena, 

 lignata in Xanthorhoe, and so on. A few other peculiarities are as 

 follows: — Ocellata, variata, sagittata, sordidata {elutata), innnanata, 

 co'siata, dubitata, badiata, albiciilata, admquata {blandiata), decoiorata, 

 flnviata, polygi-ammata, etc., are all included in the same genus ; 

 reticulata and prunata are separated from silaceata ; vitalbata and 

 tetsata are lumped with togata, sparsata, subnotata and scabiosata into 

 Eucymatoge ; coronata, debiliata and I'ectangulata are separated from 

 the great mass of Eupithecia^, whilst the tenuiata-isogrammata group 

 remain. Our five species in Lobophora get distributed over three 

 genera, and it appears impossible to explain what the generic distinctions 

 are. Candidata is in the same genus ^■5 filigranunaria, but separated 

 from biteata. Brinnata and boreata are sandwiched between blomeri 

 and cambricaria, with adustaria following the latter. Vittata, limitata, 

 plumbaria, undulata, bipunctaria, multistrigaria, didy?nata, ferrugata, 

 firmata, montanata, fluctuata, olivata, viridaria, etc., are all lumped 

 into the genus Xa?itliorha\ and separated from their allies in Hydrio- 

 mena by eight genera. The closest British allies to mscularia are 

 parthenias and notha, which are true Geometers according to Mr. 

 Meyrick. Perochraria and ochrata get transferred to different genera, 

 as also do subsericeata, inornata and aversata on the one hand from
