//. Magica Har. is ihe type, the thorax almost entirely resembles 

 that of the genus Œdionychis being ofstrongly transverse, somewhat 

 depressed shape with broadly flaltened sides; in ail ihe olher spe- 

 cies the thorax is transversely convex and very nearly resembles 

 that of Ihe genus Sebcethe. In Hyphasis the elytral epipleurœ are of 

 a most extraordinary width, more so than in any olher genus of 

 the Halticinœ, in Hyphasoma they are broad but not anything like 

 in the allied genus. In H. Wallacei Baly the posterior metatarsus 

 agrées with Œdionychis and Hyphasis is therefore equally unsui- 

 table for the réception of this species which should probably be 

 placed in another genus. 



HYPHASOMA INGONSPICUA sp. n. 



Obscure testaceus, the thorax strongly transverse, impunctate, 

 elytra scarcely perceptibly punctured. 



Length 4 mill. 



Head impunctate, strongly transversely grooved between the 

 eyes, clypeus concave at its lower portion, antennae ext^nding to 

 about the middle of the elytra, testaceous, the second joint one half 

 shorler than the third one, the foUowing joints of equal length, the 

 last two shorter; thorax about twice and a half broader than long, 

 the sides rounded, rather broadly margined, the anterior angles 

 slighlly obliquely truncate, not produced, the surface entirely 

 impunctate, scutellum impunctate, elytra only perceptibly punctu- 

 red when seen under a very strong lens, of oblong and parallel 

 shape, their epipleurœ broad and concave, posterior tibito with a 

 strong spur, the metatarsus as long as the foUowing joints toge- 

 ther, clawjoint swoUen. 



There aie two other equally small species and of nearly similar 

 coloration contained in this genus, H. feœ Jac. and H. parvula Jac. 

 from both of which the présent insect differs in the entirely testa- 

 ceous antenna3; in //. parvula the thorax bas also narrower and 

 more strongly marked latéral margins of the thorax, and in II. feœ 

 tlie antenna) hâve the second and third joint nearly equal and the 

 elytra are distinctiy and closely punctured. 



HYPHASOMA SUBMETALLIGA sp. n. 



Obscure testaceous below, the antennse, tibise and tarsi black, 

 head and thorax testaceous, impunctate, elytra metallic dark bluish, 

 very finely punctured, the apical portion nearly impunctate. 



Length 6 Unes. 



Head impunctate^ testaceous, the frontal tubercles well developed, 

 clypeus triangularly depressed anteriorly, antennae slender, black,
