of some species of Chrysomela, ^'c. 183 



vittaque lata discoidali cyaneis ; limLo externo viridi- 

 Eeiieo. 



Long. 3§ lin. 



Hab. — South of France ; Styria. 



Thorax nearly twice as broad as long ; sides straight 

 and nearly parallel from the base to beyond the middle, 

 thence obliquely converging and slightly rounded to the 

 apex, the anterior angles acute, the anterior margin deeply 

 concave-emarginate ; disk distinctly pimctured, the sides 

 coarsely variolosc, punctate, irregularly wrinkled. Elytra 

 nitidous, rather strongly punctured; interspaces irregularly 

 rugose. 



This insect, considered by Dr. Kraatz and others as a 

 small variety of Ch. gloriosa or speciosa, is nevertheless a 

 good species. The male (the only sex known to me) is 

 separated from speciosa by the much smaller size, the 

 ovate apical joint of the maxillary palpus, by the absence 

 (or nearly so) of the lateral excavations on the thorax, by 

 the concave apex of the anal segment of the abdomen, and 

 lastly, by the entirely different shape of the telurn ; in 

 the present species this organ is very short, robust, regu- 

 larly curved, obtuse at the apex, its slender and filiform 

 duct extending considerably beyond the apex of the telum 

 itself. 



Chrysomela tristis, Fabr. 



Elongata fere parallela $ ; magis oblonga, postice paullo 

 ampliata 9 ; thorace tenuiter sed distincte punctate, late- 

 ribus rotundatis (basi parallelis $) intra marginem longi- 

 tudinaliter sulcatis, sulco integro, rude foveolato-punctato ; 

 elytris sat crebre aciculato-punctatis, interspatiis rugulosis; 

 palporum maxillarium articulo ultimo ad penultimum vix 

 asquilato, apice obtuse truncato. 



Mas. — Tarsornm anteriorum quatuorarticulis basalibus, 

 fere asquilongis, modice dilatatis, semiovatis. Tarsi postici 

 articulo basali longiori ; abdominis segmento ultimo ob- 

 tuse truncato, bisinuato, apice vix producto ; telo modice 

 elongato, curvato, apice semiovato ; ducto ad teli apicem 

 jequilongo, apice paullo dilatato. 



Fcem. — Abdominis segmento ultimo obtuse angulato, 

 utrinque obsolete sinuato. 



A. Viridi-metallica aut vlridi-a^nea. 



B. Viridi-ffinea, elytris cupreis. 



C. Olivacea, viridi tincta.
