HALTICIN^S. 



Var. variabilis, Jacoby. 



Jacoby described this variety as a distinct species from Sumatra ; 

 the Burmese examples before me differ from the normal form in 

 that the pale elytral patch is enlarged to such an extent that 

 it occupies the greater part of the elytron. 



Type in the Genoa Museum. 



Var. bipustulata, Jacoby. 



In this form, described from Perak, there are only two colours ; 

 the whole insect is black and the elytral patch is a transverse 

 band across each elytron. This colour character seems to be 

 constant. All the specimens here recorded were collected by 

 Doherty from the following localities. 



Burma : Karen Mts. ; Momeik [Momeit]. Assam : Sadiya ; 

 Patkai Mts.

311. Sebaethe quadrimaculata, Jacoby. 



Sebcethe quadrimaculata, Jac, Ann. Mas. Civ. Genova, xxxii,. 

 1892, p. 922. 



Body oblong-ovate. Colour pitch -brown to black ; sometimes 

 the three basal segments of the antennas are pitch-brown like the 

 general colour of the body, the remaining segments being black; 

 a basal and a post-median area on each elytron are pale yellowish, 

 but never extend either to the lateral edges or to the suture, even 

 when they attain their maximum extent ; underside pitch-brown 

 or lighter, the apices of the posterior femora usually black. 



Head with vertex impunctate except for one or two scattered 

 punctures; frontal tubercles broad, with a faintly impressed line 

 between them, and separated from the vertex by a deeply im- 

 pressed transverse line in the interocular space ; interantennal 

 carina sharp. Antennas extending slightly beyond the middle of 

 the elytra; first segment long and club-shaped, second small, 

 third longer than second, fourth longer than third ; from the 

 fifth to the last the segments are more or less nearly equal to 

 each other. Prothorax broader than long, sides rounded with 

 their margins somewhat explanate and reflexed, anterior lateral 

 angles thickened, each of the four angles bearing a fine long 

 seta; surface smooth, shining, apparently impunciate but, seen 

 under a high power and in a suitable light, very fine and sparsely 

 distributed punctures ;»re visible, some of them, especially those 

 on the basal part, comparatively stronger ; the punctures are more 

 visible in specimens in which the pronotum is pitch-brown than 

 in those in which it is black. Scutellum triangular, with apex 

 rounded and surface smooth and impunctate. Elytra somewhat 

 broader at base than prothorax ; surface confusedly, finely and 

 more or less closely punctate. Underside covered with fine hairs.
