H ALTICINiE. 



both elytra extends from the middle of the base along the suture 

 to a certain distance, including the scutellum ; and on each elytron 

 there are a large humeral longitudinal patch, a large postmedian 

 transverse patch and smaller apical patch, all blue-blaek. 



Head : vertex convex, somewhat rugose, hardly punctate. 

 Prothorax with the surface very finely punctate. Scutellum 

 inipunctate. The other structures are exactly as under the generic 

 description. 



Length, 6-7 mm. 



Sikkim : Gopaldhara, Rungbong Valley (H. Stevens); Mung- 

 phn. Bengal: Buxa, Duars (Pnsa Coll.). 



The location of the type is unknown to me. 



In the short Latin original description, Harold designates this 

 insect " Oed. magica" the title of the short paper being " Besch- 

 reibung einiger Oed ionychis- Art en " ; these latter are mostly from 

 South America. Immediately after the description he proposes 

 the genus Hyphasis owing to the presence of certain characters in 

 this species. Evidently, then, he considered that magica belongs 

 to a separate genus and not to Oedionychis. 



Genus PHILOPONA, Weise. 



Philopona, Weise, Archiv Naturgesch. lxix, Band i, 1903, p. 216. 



Genotype, Philopona tibialis, Weise (Africa). 



Weise separated off the African and Indian species formerly 

 placed in the genus Oedionychis, Latr., and erected for them the 

 present genus (Philopona). It is characterised by possessing the 

 following tw-o features : (1) a transverse impression on each side 

 of the pronotum on the basal margin (these two impressions may 

 unite and form one impression), and (2) a longitudinal impression 

 inside the humerus on each elytron. 



These insects are generally oblong or oblong-ovate, sometimes 

 parallel-sided. Head large, as broad as the width of the prothorax, 

 with eyes strongly convex and vertex convex, the latter either 

 coarsely or finely punctate, or inipunctate; frontal elevations 

 broad, always well developed and divided by a longitudinal median 

 line, and separated from the vertex by a well-impressed transverse 

 line, which may in some cases be angled in the middle ; inter- 

 antennal carina always developed (see, for instance, Ph. mouhoti, 

 fig. 62, p. 154). Antennae generally short, extending only a little 

 distance beyond the base of the prothorax, sometimes reaching 

 about the middle of the elytra, but never equal to the length of 

 the body, not, at least, among our species : first segment always 

 the longest, thickest and club-shaped ; second always very short, 

 but it may be thicker than the third, which is elongate and 

 slender ; third to fifth nearly equal, sixth and seventh equal but 

 somewhat shorter than each of the preceding slender ones, eighth 

 to eleventh again somewhat shorter but equal t@ each other- 

 this is the general plan of the structure of the antennae, but
