interstices, as is the case in the last-named species. The three specimens contained 

 in M. Salle's collection are the only ones I have seen.

Stal, who describes this species, does not give any particulars as to the position and 

 direction of the five lines on each elytron, which it will be as well to add here. The first 

 of these, commencing a little below the base and ending at a little distance from the 

 apex, runs close and very nearly parallel with the suture, slightly approaching the 

 latter towards the posterior half; the second line, commencing at the base, runs perfectly 

 parallel with the first, and often joins the third and fourth lines at the apex; the third 

 one begins, close to the preceding one, at the base, and, after following a nearly straight 

 direction to the middle, curves outwards below the latter to a greater or smaller degree ; 

 the fourth line always commences below the shoulder, and makes a curve towards the 

 lateral margin at the middle, where it is interrupted, and then continued again parallel 

 with the others ; the fifth line runs parallel with and very close to the lateral margin. 

 All these lines finish at some distance from the apex of the elytra; and their interstices 

 are occupied at the middle by single piceous spots, placed transversely, and sometimes 

 assuming the shape of a narrow band. Thorax and underside are either metallic green, 

 cupreous, or bluish. Legs and the base of the antennas fulvous. The description given 

 here is that of the normally coloured specimens described by Stal, and of which a typical 

 one is contained in Mr. Baly's collection. Others are before me, which I must look upon 

 as varieties, since they agree in all essential points but the colour. These specimens 

 have only the base of the head metallic green ; the thorax, scutellum, and the elytral 

 stripes are fulvous or piceous ; and in some the small spots on the elytra are absent. It 

 is possible that these individuals are immature ; a specimen of the latter colour, and 

 formerly in the collection of Sturm, is labelled by him D. striolata. The figure is from 

 an insect from Juquila. 



9. Leptinotarsa novemlineata.

 Hal. Mexico, Oaxaca 1 , Juquila (JBoucard, coll. Salle). 



A distinct species, and allied to L. calceata, from which it differs in the much more 

 strongly punctured thorax and elytra, as well as in the colour of the longitudinal stripes 

 on the latter, which are not black, but brown ; they are sometimes connected with a 

 transverse spot of the same colour placed in the middle of the first and second pair of
