54 THE CANADIAN ENTOMOLOGIST. 



Very close to varicorfiis Jac. and Haroldi Baly ; from the former it 

 differs by the black tibiae and tarsi and different colouring, from the latter 

 by the narrower rufous thorax and different colouring, and from both by 

 the shorter second and third joints of the antennae, which are short and 

 equal; fourth much longer in ^ and somewhat longer in the $ ; thorax a 

 little longer than wide, lightly sinuate at the side ; elytra slightly dilated 

 behind ; what I regard as the typical form has the basal ring-shaped mark, 

 complete, contiguous at the suture, but not attaining the margin and with- 

 out any projection at the outside rear, similar to what is found in tibialis 

 and adelpha, the rear fascia is broken into broad spots, the general effect 

 being rather orange-coloured, elytra with dark spots, surrounded with a 

 lighter colour, after the manner of certain specimens of Clarke/la Baly ; 

 abdomen and femora yellow. Two of the Call examples have light 

 piceous legs (immature ?). In its elytral markings the variety, when the 

 spots are broken, much resembles seniicirculata Jac. from Bugaba. 



D. chimbo7'e?isis, nov. sp. 



Head, scutellum, pectus, and tibiae and tarsi black, antennae piceous, 

 flavous at base, joints 9-10 white, thorax a little longer than broad, rufous, 

 shining, sparsely, finely, but evidently punctured, elytra pale yellowish- 

 white, with a vivid cyaneous or bluish band at the base not attaining the 

 margin (enclosing a round yellow spot) and an oblique fascia of the same 

 colour behind the middle, femora and abdomen yellow, the former tinged 

 with piceous at the apex. Length, 6^ mm. 



Type, one example "above Chimbo., 3000 viii, '97, Rosenberg." 



Very like tibialis Jac, or adelpha Har.; frontal fovea not very deep, 

 antennae a little more than one-half as long as body, the first joint pale, 

 with piceous tip, joint 2 short, 3 one-half longer, piceous with pale bases, 

 4 slmost one-half longer than the two preceding, joints 4-8 black, 9-10 

 and base of 1 1 white, thorax comparatively longer and narrower than 

 tibialis and punctured, the forward band of the elytra, with its enclosed 

 spots, is the same marking as tibialis and adelpha, but cyaneous in place 

 of black ; the posterior fascia is almost straight-edged, oblique and not 

 right-angled or semilunate, as in the tibialis and adelpha. The form is 

 moderately dilated to the rear, and the elytra are not plicate. 



I have two examples from Caracas, Venez., which I include with this 

 species, one of which was labelled as tibialis Jac. in his second collection.
