latter has the same short form as A, pcdestris and will perhaps in 

 future prove to be only a variety of A . gibbiis Illiger. A specimen 

 from Burma {coll. Andrewes) of great size (3^X2to mm.), seen by 

 Regimbart {''amphiops sp. prope inirabilis") has been also compared 

 by Mr. Kolbe who reporrs : " dem Auiphiops gibhus sehr ahnlich." 

 I also think it may be gibbus. The punctuation of the pronotum is 

 more obsolete (perhaps because of the greater size), the interstices 

 of the elytra very shining, on the apex without the finer punctua- 

 tion of pedesiris. I could not detect other differences. It is im- 

 possible, however, not to feel some doubt in the determination of 

 these difficult insects and a thorough revision with access to all 

 typical material would be desirable. 



I take this opportunity of describing a form which has come 

 to light in my study of the Dibrugarh material. 



Amphiops pedcstris var. varians, nov. 



Type : a specimen in my cabinet, from Pondichery, Coroman, 

 delj June, 1901 (M. Maindyon). Determined h\ Regimbart" as A. 

 muabilis. 



Differs from typical A . pedestris in the shorter, more highly 

 convex body, the punctuation of the sides of the elytra, the serial 

 and interstitial punctures being nearly of one size, but less distinctly 

 mixed together with very fine smaller punctures, the disc of the 

 elytra round the scutellum rather more obsoletely punctured, 

 more shining and smoother, the series of large punctures more 

 effaced before the base, even at a distance from the scutellum. 

 The interstice between the ist and 2nd internal (visible) series 

 of larger punctures is nearly as wide on the base as the sutural 

 interstice (because of the obliteration of a series and of the inter- 

 stitial punctures) and the size is generally smaller. Colour more 

 rufescent. The variet}' seems to be common : tliere is a long 

 series in the Brussels Museum from Mandar (Bengal) and Konbir 

 {R. P. Cardon). 



This is most probably the form named pedesiris in Ann. Soc. 

 Ent. Fr. 1903, p. 62, by Regimbart, who seems not to have correctly 

 known Sharp's A. pedesiris and niirabilis.
