d(caspila Baly. The elytral pattern is almost exactly duplicated in some 

 of the varieties of lo guttata Oliv., but the antennal joints at once 

 differentiate it. 



D. iinicincta, no v. sp. (Jac. in litt.). 



Head black, antennce dark piceous, last three joints flavous, thorax 

 rufous, shining, impunctate, except the sides, broadly depressed and lightly 

 trifoveate, scutel bUck, elytra black, tinged with cyaneous, obsoletely 

 plicate, strongly dilated posteriorly, shining, punctate, with lateral margin 

 dilated at the apex, a narrow curved fascia behind the middle, and suture 

 narrowly from the fascia to the apex flavous, below black, wiih abdomen 

 and bases of femora yellow. Length 6-7^ mm. 



Three examples, Marcapata, Peru. 



Antennae three-fourths as long as the body, joint 3 one-half longer 

 than 2, which is short, 4 longer than the preceding two united, four or 

 five lower joints light piceous, the last three, apex of the eleventh excepted, 

 flavous ; thorax about as long as broad, sides very lightly sinuate, finely 

 punctured at the sides, broadly depressed (one example very lightly) 

 behind ; the side foveas small, but distinct, the third subobsolete, placed 

 just before the scutel, whicli is dark piceous ; the elytra differ in colour in 

 each of the examples before me, black, black tinged with green, dark 

 steel-blue ; all, however, have the margin, apex and fascia and one the 

 sutural border flavous, as above described ; the form is broadly dilated at 

 the rear, slightly depressed behind the scutel, surface evenly and moder- 

 ately ])unctured, with a tendency to be semisulcate longitudinally, 

 especially near the apex. 



The species has been distributed with the manuscript name iinic'mcta 

 Jac. Two of my specimens were sent me as co-types by Messrs. Staudinger 

 and Bang-Haas; one of them seems as if it might be a diffcirent species 

 (angusiofasciata Jac. in litt.?), as the fascia is almost transverse in place 

 of being curved, and the thoracic depression is wanting ; what I take as 

 the type is the other example, having black elytra, a narrow curved fascia 

 and depressed thorax, the longitudinal ridges of the elytra showing at the 

 sides and rear, and the femora very slightly flavous at the base. 



D. semiviridis, nov. sp. (Jac. in litt.). 



Head, antenna?, legs and breast black, thorax greenish, flivous, con- 

 vex, shining, very lightly foveate and punctate, elytra not plicate, 

 prasinous, with a dash of orange, coarsely, confluently punctate, with a
