HALTICINjE. 



Length, 5 mm. ; breadth, 4 mm. 



Bombay : Kanara (type-locality of A. laevigata). Bengal : 

 Mandar (Pere Cardon, type-locality of A. bistripunctata). Anda- 

 man Islands : many specimen* in the British Museum (Captain 

 Wimberley and Roepstorff). Indo-China : Laos (Mouhot). 



Location of type of A. bistr (punctata unknown to me ; Mons. 

 Severin informs me that there are no examples under this name 

 in the Brussels Museum. Type of A. laevigata, Jac, in the 

 British Museum. 



Jacoby, when describing A. laevigata, was aware that Duvivier 

 had described A. bistripunctata, but he differentiated the former 

 from the latter as follows : in A. Icevigata (1) " the antennae 

 extend to the base of the prothorax," (2) " the entire upper surface 

 is without punctures or the latter are so fine as to be practically 

 called absent," (3) 1,4 there is no trace of a double row of punctures 

 at [sic] the elytra or at the sides," I have examined the type of 

 A. Icevigata and find that the above observations are not correct ; 

 Jacoby s error may have been due to using too low a power of 

 magnification. 



Weise erected the genus Chilocoristes (Deutsch. Ent. Zeitschr. 

 1895, p. 336) with Argopistes bistripunctata, Duviv., as the 

 genotype. It is possible that this species does really belong to 

 a distinct genus, but without examining more material I do not 

 wish to follow Weise, and therefore propose to retain bistri- 

 punctata in Argopistes. ]t nmy be recognised, however, that 

 Argopistes is a very artificial genus, at least so far as the species 

 from our regions are concerned. 



210. Argopistes nigromarginatus, Jacoby. 



Argojnstes nigromarginatus, Jac, Ann. Mus. Civ. Genova, xxxii, 

 1892, p. 931. 



Brown ; antennae, legs, and abdomen lighter brown ; base of the 

 head black ; lateral margins of prothorax black, which colour is 

 continued along the lateral and apical margins of the elytra. 



Head with vertex impunctate, face strongly deflexed. Antennae 

 scarcely extending beyond the base of the prothorax: second 

 segment equal in length to third, fourth slightly longer ; the 

 terminal segments rather thickened. Prothorax more than twice 

 as broad as long, strongly narrowed in front, sides straight, 

 posterior margin very rounded, sinuate at each side ; surface 

 extremely closely and finely punctate. Scutellum small, triangular. 

 Elytra punctate like the pronotum, the disc also with rows of 

 piceous punctures. Underside : posterior tibiae with a large 

 double spur. 



Length, 4| mm. 



Burma: Karen Hills, xii. (Fea). 

 Type (unique) in the Genoa Museum. 



I have not seen the type of this species. The above description 

 is adapted from the original.
