prothorax : the colour of the ely tra also varies froni blue to dark violaceous : 

 the localities given for the species are Hoozan, Taihorin, Kosempo, 

 Kankau (Koshun) and Kanshirei: there are seven examples of Tetra- 

 languria elongata Fabr. var. pyramidata Mc Leay (five from Taihorin, 

 one from Kankau and one from Kosempo) and eighteen of Anadastus 

 (L&nguria) melanosternus Har. (all from Kankau, Koshun): among 

 the others are several species which appear to be undescribed. 



Tetralanguroides Fowler. 



(Trans. Ent. Soc. Lond. 1886, 315). 



I described this genus for the reception of a species in Crotch's 

 collection, labelled as the type of a new genus which I named as T. 

 fryi: Gorham subsequently proposed to drop the genus or he considered 

 the insect to be a composite one, an ordinary Tetralanguria with a 

 different head affixed: I am not prepared to say definitely that 

 this is the case, but I have had an opportunity recently of again 

 examining the insect and it is in such very poor condition (having 

 evidently, since I sa w it last, been soaked and taken to pieces and put 

 together again), that I prefer to sink it as the type of the genus and 

 to Substitute the species described below, which answers to the 

 description of the genus, except that the apices of the elytra are in 

 the type specimens very obtusely pointed and notched internally 

 and not truncate. 



Tetralanguroides sauteri sp. n. 



Tetralanguriae elongatae quoad formam valde äff inis : viridiscenti- 

 aeneus vel aenescens. Capite sat fortiter punctato, antennis robustis, 

 clava distincte 5-articulata : prothorace plus minusve convexo, lati- 

 tudine paullo longiori, levissime ßed distincte punctato ; elytris apices 

 versus angustioribus vel subparallelis, leviter punctato-striatis, inter- 

 stitiis plus minusve rugosis, apicibus obtuse angustatis, productis: 

 pedibus piceis, corpore subtus piceo-brunneo. 



Closely allied to Tetralanguria elongata from which it may easily 

 be distingtiished by the 5-jointed club: greenish aeneous or aeneous 

 above, pitchy or brownish-pitchy beneath: head rather st rongly punctured : 

 prothorax more or less convex, very finely but plainly punctured, 

 rather longer than broad, with the base depressed: elytra gradually 

 narrowed from. apex to base, with rows of fine punctures and with the 

 interstices more or less distinctly rugose: legs dark, pitchy: apices of 

 elytra separately pointed obtusely and slightly notched, with a 

 depression followed by a callosity at the extreme end: coxal lines 

 more or less distinct, resembling those of Tetralanguria. 



Length 10 — 11 mm. 



Three examples, one labelled Taihorin 1911, and two Kosempo 

 1909 and 1911: one of the two latter has the prothorax less convex 

 and the sides more parallel and answers exactly to the insects below 

 described as a variety, except in the ehape of the apex of the elytra : 

 unfortunately the antennae are both broken.
