LEPTINOTARSA. 231 



stripes. The body and thorax in the present species are of a more coppery colour, 

 instead of blue or green, as in L. calceata. Besides four specimens contained in 

 Mr. Baly's collection, I have seen but three others from Juquila. 



10. Leptinotarsa flavitarsis. (Tab. XIV. fig. 12.)

 Nicaeagua, Chontales (Janson, Belt) ; Costa Rica (Salle). 



Mr. Baly gives Mexico as the country inhabited by the present species, and a 

 specimen in his collection is labelled accordingly; but I have not seen any others 

 obtained there, all the specimens which have come under my observation having been 

 collected at the places given above. The colour of the underside and thorax is either 

 metallic dark blue or bright green ; but the apex of the tibiae and the tarsi are always 

 light fulvous, which separates it from the following species. 



11. Leptinotarsa nitidicollis.

In coloration L. nitidicollis exactly resembles the preceding species, except in that of 

 the tarsi and tibiae, which are of the colour of the body. A closer examination reveals, 

 besides this difference, several others. In general shape the present species is rather 

 more convex and widened posteriorly, and the punctuation of the elytra is also much 

 finer and less closely arranged; lastly, the elytral bands are thinner, and seldom 

 continued, but nearly always interrupted at the middle. I have seen but few speci- 

 mens, and those from one locality only. 



12. Leptinotarsa calceata. (Tab. XIII. fig. 14.)

Great numbers of this species were obtained by Herr Hoge at Misantla. In the 

 flavous apex of the tibiae and the tarsi of the same colour, the insect agrees with 

 L. flavitarsis, but differs in the four narrow blackish stripes of the elytra ; of these, the 

 first one is placed near the suture, commencing directly below the base and finishing at 

 a considerable distance from the apex; of the three following stripes the middle one is
