444 MR. MAUTIK JACOBY ON NEW SPECIES [Nov. 28, 



by Clark, and foi'inerly in the Baly collection. The colour of the 

 elytral bands, their shape, and the more than usually convex and 

 widened genei'al shape of the insect, distingiiish this species. 

 Whether 0. jaculus Illig. is identical with this or some other 

 similarly marked species I am unable to say, but Illiger's 

 description of the shape of the elytral bands does not agree with 

 that of the insect before me. 



Oedionychis regina, sp. n. (Plate XIY. fig. 12.) 



Large and broad, black, the last two joints of the antennae pale 

 yellow ; thorax impunctate, flavous, with a large black ti'ansverse 

 band ; elytra stiongly and very closely punctured, metallic dark 

 green ; the lateral margins and a transverse band below the 

 middle testaceous. 



Length 10 rnillim. 



Head bluish-black, impunctate, except near the eyes, the latter 

 with a flavovis spot near the inner margins, widely separated ; 

 antennfe slender, black, the last two joints pale flavous, third 

 joint slightly shorter than the fourth ; thorax rather more than 

 twice as broad as long, the sides broadly flattened, evenly rounded, 

 the anterior angles thickened, very slightly prodviced outwards, 

 the disc impunctate, black, the lateral and basal margins flavous ; 

 scutellum black ; elytra widened below the middle, closely and 

 strongly rugose-pvmctate, metallic green, the lateral margins 

 nari'owly and a slightly wider transverse band, immediately below 

 the middle, testaceous ; under side and legs black. 



Hah. Espuito Santo, Brazil. 



The black thoi'acic band which extends to the anterior margin, 

 the colour of the antennae, and the strongly punctured elytra well 

 distinguish this species from any other. 



Oedionychis dipficilis, sp. n. (Clark, MS.). 



Black, thorax flavous, impunctate ; elytra convex, widened 

 posteriorly, closely and finely punctured, flavous, a broad trans- 

 verse band at the base and another band below the middle, with 

 the lateral aiid posterior mai-gins rounded, metallic blue, both 

 bands not extending to the margins. 



Length 6-9 millim. 



Head imj)unctate, black, two or three deep punctures are 

 placed near the eyes, frontal tubercles trigonate, nearly connected ; 

 antenna? rather long, black, the base at their insertion flavous, 

 third and fourth joints nearly equal ; thorax twice as bioad as 

 long, the sides rounded anteriorly, the anterior angles produced 

 into a small tooth, the disc impunctate, flavous or fulvous ; 

 scutellum black ; elytra widened towards the middle, convex, 

 finely and closely punctvu'ed, flavous, with two transvei'se dark 

 blue bands — the first at the base, of regular shape, with its 

 posterior edge sti'aight and not qxiite extending to the middle, 

 the second band below the latter, its anterioi- margin straight, 

 but the lateral and apical margins rounded, the last-named some-
