82 THE entomologist's record. 



of the Old World, orthopterists have alwaj's been handicapped by the 

 difficulty in determining uccut-iitily the large-winged locusts which are 

 typified by the common Arri'liimi aiin/iitiiiui, Linn. 



Serville <lescribed a number of species, but confusion was involved 

 by Francis Wall<er (1H70), who divided the genus into two, Acridinm, 

 Geotlr., and Ci/rtacanthacris, Walker, and described over a hundred 

 new spe.-ies in the two genera combined. Walker includ( d all the 

 species at present ranged in Schistocevca, Stal. As his descriptions 

 are insufficient, and based upon non-scientific chaiacters, a re\ision 

 of his types in the British Museum would be a valuable piece of 

 work. . 



In 1873, Stal reformed the genus in his classical " Eecensio 

 Orthopferorum " ; the learned Swede neglected Walker entirely, and 

 created a new genus — Schistuceira — based on the form of the ceici of 

 the male; the American species fall into this genus iind also the 

 notorious migratory locust S. iicref/iina, Oliv., of the Old World. This 

 genus has been ably dealt with by Scudder (ly99). 



Since the appearance of S;ars work, various authois have 

 published upon this genus, among whom we may mention l>olivar, 

 Braiicsik, (lerstaecker, Karsch, Kirby, Krauss and Karny. A very 

 valu:ible addition to the systcnnitic literature of the genus ha-; recently 

 appeared from the pen of Capt lin Adrien Finot. The nomenclature 

 of Kar-ch is rejected, and the much-debated name Arridiuni, Serville, 

 is retained, agreeably to the usage of Stal and lirunner. 



The structure and characters are discus-ed with that conscientious 

 minutiness of detail which characterises all the work of Captiin 

 Finot. This port'on of the memoire occupies ten pages, and is illustrated 

 by a number of useful diagrammatic skeiches. Then follow the 

 descriptions of the species represented in the author's own collection; 

 these number 28, of which one is a species of Walker's, which Cap ain 

 Fmot has been able to identify, and eight are new. 



This portion of the work is fo lowed by asynoptic.il table of all 

 hitherto des -ribed species ; this alone is a monument of patience, for 

 it was compiled purely from the descriptions, often very in-ufficient, 

 of the older authors ; it includes no fewer than 1'25 species, the majurity 

 from the descriptions of Walker. A second table is appended of the 

 28 species contained in the author's own collection ; needless to say 

 this is a very much more scientific piece of work. 



The chief points of synonymy established in this paper, are as 

 follows: — (1) lineola, Fa.hr. = iii'i/!//itiitiii, Ijmn.; (2) tartan'riiin, hinn., 

 is a good species, of which lineatnut, Stoll, is a synonym; (8) rujirurne, 

 Fabr., is distinct from citrinnm, Serv. ; and (4) jiaviconw, Oliv., is 

 provisionally retained as a synonym of rosenni, de Geer. 



As a critical essay upon a difficult genus, this is an important 

 piece of work, and a valuable basis for a future complete monogiaph 

 of the group, which must include a complete revision of W^alker's 

 numerous types in the British Museum. 



Malthodes minimus, L., var. marginicollis, Schilsky, a variety 

 new to the British List.

 I swept a Malthodes at Cobham Park, on July 7th last, which I was 

 unable to name satisfactorily, so I sent it to Herr Ganglbauer, who
