PhytopJiagous Coleoptera, §-c. 237 



elytron, close to the lateral margin, is a broad flavous vitta 

 which extends from the shoulder nearly to the sutui'al 

 angle ; from its obliquely truncate base it gradually narrows 

 to its apex. Mesosternal spine robust, acute, equal in 

 length to the metasternum. 



This insect, which is very similar in form to D. his trio 

 and its allies, closely resembles in pattern and coloration 

 certain species of Mesomphalia coming fi-om the same 

 part of the world ; it also somewhat agrees, in the pattern 

 of its elytra, with D. insularis, Jacoby, but its general 

 form, broader thorax, and coarsely-punctured elytra, will 

 separate it from that species. 



Doryphora decipiens. 



Ovato-rotundata, convexa, nigra-fenea, nitida; antennis 

 (basi excepta) nigris ; thoi'ace utrinque prope marginem 

 excavato, remote tenuissime punctate ; elytris regvdariter 

 punctato-striatis, vitta intra suturam, altera submarginali 

 apice coeimtibus, limboque basali inter has vittas fulvis. 



Long. 4 lin. 



Hab. — Chanchamayo. 



Head very minutely granulose, finely punctured, front 

 impressed with a faint longitudinal groove ; antennas half 

 the length of the body, black, the base piceous. Thorax 

 more than twice as bi'oad as long ; sides straight and 

 obliquely converging ft-om the base to beyond the middle, 

 thence rounded, and more quickly converging to the apex, 

 the anterior angles acute ; disk transversely convex, dis- 

 tinctly excavated on either side near the lateral margin, 

 surface very minutely and remotely punctured. Elytra 

 broader than the thorax, each impressed with two regular 

 rows of punctures, the first short, their interspaces plane ; 

 the fourth and tenth interspaces, confluent at their apices, 

 together with the basal limb between them, fi.il vous. 

 Mesosternal spine shorter than the metasternum, robust, 

 its apex obtuse. 



Leptinotarsa Kirschi. 



Ovata, convexa, nigro-picea, nitida, capite thoraceque 

 rufo-piceis, hoc disperse tcnuiter punctate, antennis basi 

 excepta, nigris ; elytris regularitcr punctato-striatis, flavis,
