nation. "^Of the remaining twelve species, four appear to lie already known, while twn new 

 genera, eight new species and one new subspecies are here described for the first time. It lias 

 also been necessary in the course of the work to re-examine some of the criteria used in tlie sep- 

 aration of tlie sul)families and tril>es of the Lygacidac, and to study rather closely certain 

 members of the genus Xysiits allied tn A', cricac (Schiil. ). The results of these studies are 

 set out in the appropriate places below. .\.ll species in any way associated with a(|uatic 

 localities will Ix; described in a later paper. 



In general Oshanin's catalogue (I'Jlii has been followed as to nomenclature and classi- 

 fication. Bibliographic references are given for all si)eciiic names not included in that work, 

 but otherwise only to papers to which actual reference is made in the te.xt. A representative 

 set of all species, including the types of those here descriljed, has been incorporated in the 

 collections of the Peabody Museiun, Yale University: a first set of duplicates has been sent 

 to Mr. China for the collections of the llritish .Museum.

1. Phimodera rupshuensis sp. n. 



\\'idel\- oval ( I'late \ III, fig. 1 I, holotype 1.44 times as long as wide; moderately conve.x, 

 opaque, covered with short, sparse pale jnibescence; head, save for the raised parts of the 

 jugae and clypeus and the regions at the bases of the eyes, pronotum, scutellum and exposed 

 portions of the elytra, punctured, the distance between the punctures very irregular, averag- 

 ing rather more than their diameter, under surface punctured but more sparsely so. 



Color. I'ale greyish yellow, puncturation black, head black, a narrow area round the 

 eyes, jugae particularly in their raised part, and base of the clypeus largely yellow, a large spot 

 on the anterior margin of the pronotum, and the base of the scutellum black; basal joints of 

 antennae brown, the first and second narrowly yellow apically, terminal two joints black ; 

 anterior femora with a black ventral stripe and a less w-ell defined posterior stripe fusing with 

 the black puncturation dorsally, intermediate and posterior femora with black postero-ventral 

 stripes, tibiae black a])ically and basally, on the dorsal surface the dark markings forming a 

 .stripe interrui)ted in its middle third, first and di.stal half of third tarsal joints dark brown. 



Head. In front view (Plate \TII, fig. 2), about one-sixth longer than intemcular 

 width, subparallel and hardly constricted in front of the eyes, juga with outer angle widely 

 rounded, anterior margin lightly curved from the external to the .sub-obtuse inner angle, inner 

 part of the juga in its basal half .somewhat raised and encroaching on the clypeus; clypeus 

 anteriorly subacute and jirojecting Ijeyond juga, carinate in its anterior part, carina depressed 

 posteriorly, Ijecoming obsolete opposite the elevated part of the juga, vertex behind clypeus 

 somewhat elevated. Ocelli .separated from eye by a space sulKjqual to the maximum diameter 

 of the eye and rather greater than its width. F)ucculae subprominent below clypeus, obtusely 

 rounded behind (Plate VIII, fig. 3).
