of Chrysomela from the East. 95 



and apex impressed with very fine remote punctures ; whole surface 

 distantly reticulate-aciculate ; a large irregular ill-defined patch at the 

 base, nearly covering- the space above the transverse groove, and four or 

 five broad vittae, confluent at their base and apex, extending from the 

 hinder margin of the groove to the apex of the elytron, rufo-violaceous ; 

 in the centre of the hinder disk is also a short deep-metallic-blue stripe.

This beautiful species is very closely allied to C. quadri-impressa, 

 and when first received, I considered it as merely a local variety of 

 that insect ; subsequently, however, it has been sent in some abun- 

 dance, and after a careful examination of many individuals, I have 

 come to the conclusion that it has a just claim to be considered a 

 good and distinct species. It differs from C. quadri-impressa in the 

 following characters: — it is larger, less regularly oblong, being 

 slightly broader behind ; its convexity is greater, particularly on the 

 hinder portion of the elytra, which are also obsoletely gibbous in 

 their middle ; the whole body is much smoother, far less closely 

 and coarsely punctured ; the punctate striae on the elytra are di- 

 stinct over nearly the whole surface, whilst in the other species 

 they are so mixed up with the coarse irregular punctation of the 

 whole elytron, that they are only visible at the base ; the thorax is 

 more dilated on the sides, its disk is smoother and covered with much 

 finer punctures, interspersed here and there with a few deeper im- 

 pressions, which are much larger and more distinct than those in 

 0. quadri-impressa ; lastly, the grooved line bounding the upper edge 

 of the epistome, instead of being triangular, forms a regular curve. 



3. Chrysomela Stalii. 

 C. ovata, convexa, nitido-cuprea ; thorace disco lasvi, impunctato, lateribus 

 a basi ad paullo ante medium leniter ampliatis, hinc ad apicem rotun- 

 dato-angustatis, incrassatis, intra marginem profunde punctatis ; elytris 

 profunde punctato-striatis, punctis magnis, striis per paria subapproxi- 

 matis, hie illic sulcatis. — Long. 4 lin. 



Ovate, convex, shining cupreous. Head finely but sparingly punc- 

 tured. Thorax nearly twice broader than long ; sides moderately di- 

 lated from the base to just before their middle, thence rotundate-an- 

 gustate to the apex : upper surface smooth and shining, convex and 

 inipunctate on the disk; sides incrassate, bounded within, for their 

 whole length, by a broad but shallow longitudinal groove, the surface 

 of which is covered with large, deep, round punctures ; these, although 

 somewhat crowded, are rarely confluent. Scutellum smooth, impressed 

 in the middle with a single fovea. Elytra broadly ovate, very convex, 

 deeply punctured, the punctures varying greatly in size and depth, and 

 arranged, somewhat irregularly and at unequal distances, in ten longitu-
