and Species o/*Gallerucina3. 113 



gulate in the middle; disk rugose. Elytra oblong-ovate, 

 rather coarsely punctured, interspaces granulose punctate. 



Very similarly coloured to M. cynicus, Clark, one half the 

 size, much narrower and much less regularly ovate. 



Haplosonyx concinnus. 



H. elongato-ovatus, convexus, rufo-fulvus, nitidus, genibus, tibiis 

 dorso, tarsis antennisque nigris, his apiec flavo-albidis, basi 

 fulvis ; thorace lawi, utrinque excavato ; elytris viridi-aeneis, 

 concinne sat fortiter punctatis, obsolete costatis, utrinque infra 

 callura humeralo oblique sulcatis. 



Long. 6-7 lin. 



Hob. Celebes. 



Vertex and front finely but distinctly punctured ; encarpae 

 thickened, shining, impunctate, pyriform, separated by a deep 

 groove : antennas filiform, four fifths the length of the body, 

 the second joint short, the third four times the length of the 

 second, nearly equal to the fourth and fifth united ; the two 

 or three lower joints fulvous, stained above with black, the 

 three or four upper ones yellowish white : apices of jaws black. 

 Thorax twice as broad as long ; sides obtusely angled just 

 before the middle, sinuate behind the latter, the hinder angles 

 recurved, thickened, acute, the anterior ones mucronate ; upper 

 surface nearly impunctate, broadly and deeply excavated on 

 either side, the excavation extending to the lateral margin. 

 Scutellum wedge-shaped, its apex obtusely truncate. Elytra 

 broader than the thorax, narrowly ovate, slightly dilated be- 

 hind the middle, obliquely rounded towards the apex, the ex- 

 treme apex of each truncate ; above convex, closely and rather 

 strongly punctured ; each elytron with three or four ill-defined 

 longitudinal costae, only visible on the middle disk (in some 

 specimens these costs? are entirely obsolete); immediately below 

 the humeral callus is a broad and ill-defined but distinct sul- 

 cation, which extends obliquely downwards and inwards for 

 one third the length of the disk ; immediately within the 

 suture is also a very shallow depressed longitudinal space. 

 The very long third joint of the antenna will at once sepa- 

 rate this insect from its congeners. 



Haplosonyx speciosus. 



H. angusie oblongus, convexus, rufo-fulvus, nitidus ; oculis, mandi- 

 bulis apice, genibus, tibiis tarsisque nigris ; antennis pallido 

 flavis, articulis tertio ad quintum pibeis ; thorace transvcrso, 

 medio obsolete foveolato, utrinque transversim sulcato ; elytris 

 oblongis, utrinque infra basin arcuatira excavatis, tenuitcr punc-
