THE CANADIAN ENTOMOLOGIST. 15 



Head with a sharp, round frontal fovea, antennse about half the length 

 of the body ; joint 2 short, chubby ; 3 one-half longer, more cyHndrical ; 

 4 as long as preceding two, 1-3 and base of 4 yellow, then dark piceous 

 to the 9th, then flavous to the piceous upper half of the nth, thorax 

 broader than long, sides strongly sinuate, disk very obsoletely trifoveate, 

 elytra scarcely dilated to the rear ; punctures close and even, somewhat 

 dulling the shiny appearance, the sutural spot is broad and abruptly 

 attenuated to the rear, where it is drawn out as a thread-like line on the 

 edge of the suture, gradually fading away about the middle, humeral spot, 

 joining the sutural at the extreme base ; the ist lateral spot is large and 

 round at the median side, and the 3rd lateral spot is on a line with the 

 discal, and probably at times connected with it. The general effect is 

 bright yellowish-green, with three basal and two lateral and a small hind 

 spot rufous piceous. I place it next atomaria Jac. 



D. fieoatromaculata^ no v. sp. 



Head and breast black, antennae fuscous, thorax rufous, convex, shin- 

 ing, very finely and sparsely punctulate, elytra slightly plicate, dull orange, 

 with a common triangular sutural spot, a broad humeral sublateral stripe 

 extending to the middle and just before its end, extending inward toward 

 the suture, and a curved fascia between the apex and middle, concave 

 behind arjd not reaching either the margin or suture, all cyaneous blue, 

 beneath and legs yellow, tibiae and tarsi dusky brown. Length 5 mm. 



One example, Rio ^lixiollo, Prov. Huallaga, Peru (G. A. Baer, Aug. 

 8, 1900). Shape, size and general appearance of atromaculata Baly, but 

 with black tarsi and tibiae. 



Head vvMth well-marked frontal fovse, antennae ^ length of body, 

 joints 2-3 short, about equal ( c^ ?), 4 longer than both together ; 5, 8 and 

 1 1 are darker fuscous ; thorax longer than broad, lightly sinuate behind, 

 the two ordinary foveas are visible only at certain angles as minute de- 

 pressions, punctuation of elytra moderately thick and even at the base 

 and middle, becoming sparse towards the apex, the cyaneous markings 

 have the appearance of being impressed, so that the yellow central parts 

 seem slightly raised ; the tibia and tarsi are about the colour of the darkest 

 part of the antennae. 



The elytral markings are almost exactly those of atromaculata Baly, 

 the colour of which is given in the description as black, but an example 

 in my collection (ex Baly) has the markings /^///^-black, but the dark tibia 

 and tarsi will at once separate the two.
