244 PHYTOPHAGA. 



sufficiently indicated in the figure), and light or darker testaceous, covered with 

 very numerous small black spots, each of which surrounds the impressed punctures. 

 These latter are very irregularly distributed, for the most part united in pairs, which 

 form semiregular rows well visible with the naked eye; below the base and imme- 

 diately below the middle, the elytra are traversed by two black irregularly dentate 

 transverse bands, which either extend quite to the lateral margin or are abbreviated at 

 the sides. Stal describes these bands as being " seneo-ferrugineis," no doubt from an 

 immature specimen ; all those before me, to the number of ten, have black bands. 

 The extreme lateral margin, as well as the elytral epipleurse, are generally dark red or 

 crimson-coloured ; but in some specimens the colour is uniform with the rest of the 

 surface. All, however, have at the inner margin a black spot, corresponding in its 

 position with the first transverse band — that is to say, in a line with it. 



5. Doryphora panamensis. (Tab. XV. fig. 11.) 



Oblong-ovate, narrowed behind, greenish black ; elytra obscure testaceous, a transverse band below the base, a 

 round subsutural spot near the middle, and numerous minute spots at the disk, piceous. 



Var. Smaller; elytra bright yellow, their epipleurae red, interrupted below the base by a longitudinal black 

 spot. 



Length 6-7 lines. 



Head remotely and rather finely punctured; antennas greenish black, the basal joint testaceous below, terminal 

 joints gradually widened and flattened, longer than broad. Thorax more than twice as broad as long, the 

 sides nearly straight near the base, gradually rounded towards the anterior angles, the latter deeply 

 concave behind the eyes, surface very little shining, irregularly and rather remotely covered with very 

 distinct but not deeply impressed punctures, the sides a little more closely punctate ; scutellum triangular, 

 the sides slightly rounded, surface smooth. Elytra distinctly narrowed behind, convex at the base only, 

 from there to the apex gradually deflexed, the disk subgeminately punctate-striate near the suture, the sides 

 very irregularly and deeply punctured, all the punctures surrounded, as well as their interior, by piceous 

 or black, the interstices also finely punctured here and there ; a transverse band, narrowed and abbreviated 

 at the sides, extends across the suture directly below the base, and is followed immediately below by a 

 small round spot placed close to the suture ; another elongate black mark is placed below the base at the 

 inflexed margin of the elytra. The mesosternal process robust and slightly curved.

In the shape of the elytra the present species somewhat resembles D. circumflexa, 

 St., and allied forms, while their markings are not unlike B. petulans and several 

 others. From the latter species the narrowed shape of the insect, the less rounded 

 appearance, and the form of the band below the base in connexion with the isolated 

 spot near the suture will at once distinguish it. A* specimen from Chiriqui agrees 

 entirely with one in my collection, but has the sides of the elytra stained with piceous, 

 as if the black rings surrounding the punctures had united there. In the variety, the 

 elytra are bright yellow, and their epipleurse crimson-red, which colour spreads also along 

 the extreme lateral margin, as is the case with some specimens of D. petulans. I may 

 add, further, that in the last-named insect the interstices between the punctures of the 

 elytra are always impunctate, which is not the case in D. panamensis.
