328 COLEOPTERA. 



Leptinotarsa vittipennis nov. sp. 



Head and thorax dark shining metallic green, labrum rufescent, 

 antennae dark, punctuation of the head moderate and uniform, diffuse 

 on the thorax and coarser at the sides, scutel dark, elytra dark fiavous, 

 coarsely, diflfusely punctate, except on the disk where it is semi-regular 

 with a common sutural vitta which is suddenly widened just before the 

 middle and abruptly narrowed after the middle, to a thin line which 

 attains the apex ; a broad (about 1 mm.) oblique vitta from the 

 humerus to a point about one-third from the apex, but only attaining 

 the convexity, and a small elongate subbasal spot between the two 

 vitta, all of which are the color of the thorax, body below and legs 

 dark greenish black. Length 9 mm. 



One example, Peru, pale green label (Marcapata ?). 



The suddenly narrowed sutural vitta and the broad oblique 

 humeral stripe make this a conspicuous form. The antennae 

 are long and approach the form of Prosicela, but the outer 

 joints are widened; the surface of the thorax is polished and 

 the punctures rather sparse except on the rear edge ; there 

 is a well marked quasi arcuate fovea near the hind angle, 

 the punctuation of the elytra is moderately coarse and diffuse 

 except for a few short striae on the disk. 



Desuiogramina seiiiifulva nov. sp. (Jac. in litt.). 



Head and thorax sanguineous, moderately punctured, labrum black- 

 ish, antennae black, basal joints rufous, scutel black, elytra dull green- 

 ish black, moderately punctate striate, the third, fifth and ninth inter- 

 vals and the basal margin light fiavous, the light intervals wider than 

 the others, the ninth the widest of all, all three joining just before and 

 then reaching the apex, body beneath and legs dark black green, 

 coxae rufous. Length 7 mm. 



Two examples, Callanga, Peru. 



This species is labelled semifulva Jac. as I am unable to 

 find the description I give the above, the elytral striping 

 much resembles Ljunghi Stal or Nigripes Jac, but the bright 

 red thorax and the dull black of the elytra in conjunction with 

 the light vittae distinguish it. The punctuation of the thorax 

 is as usual a little thicker and coarser at the sides which are 

 rounded with pointed anterior angles ; the elytral punctures 

 are fine, and the dark surface noticeably dull shiny, 



Desmograiiinia jacobyi nov. sp. 



Head and thorax dark, dull green bronze, labrum tinged with rufous, 

 antennae of the same dark green with rufous basal joints below, punc-
