THE CANADIAN ENTOMOLOGIST. 91 



thorax in the Klages specinien which 1 regard as ihe 9 is faintly 

 bifoveate, the elytra are very sh"ghtly dilated behind, so the general 

 a})pearance is parallel with two conspicuous black spots behind. 



D. calhwgaensis^ nov. sp. 



Head black, antennae dark fuscous, base and three apical joints pale, 

 thorax pale rufous-flavoiis ; shining, punctured, depressed, bifoviate, scutel 

 flavous, elytra pallid yellow, obsoletely plicate, dilated behind, witli a 

 siiblateral blue-black stripe from the shoulder, along the side for about 

 two-thirds the elytra ; the suture is also narrowly tinged with the same 

 colour on the anterior half or two-thirds ; below flavous, with pectus black; 

 legs flavous, with dark fuscous tibiae and tarsi. Length, 6^^-712 mm. 



Five examples, Callanga and Vileanote ? Peru. 



The antennre are more than three-fourths as long as the body, slender, 

 joint 3 nearly one-half longer than 2, 4 equal to the two preceding, the 

 four or five lower joints flavous, and the three upper ones, the extreme tip 

 of the last excepted, pallid ; the thorax is a little wider than long, the 

 punctuation scattered but very obvious ; the punctures of the elytra are 

 fine and even. 



^t2ii facialis Baly, but smaller and more pallid. 



D. neolineata, nov. sp. 



Head flavous, labrum black, antennae light yellow-fu3COU==, lightest at 

 base and apex ; thorax flavous-rufous, smooth, shining, depressed behind, 

 and obsoletely bifoveate ; scutel yellow, elytra pallid yellow, plicate, 

 smooth and finely punctured ; three longitudinal blue-black lines at the 

 base, one sutural common, the other basal humeral, also two behind, one 

 discal on the convexity, the other sublateral; below and legs pallid yellow, 

 pectus black. Length, 5-6 mm. 



Three examples, Mapiri, Bolivia. 



I also place here three examples from Pachitea, Peru, which difter 

 somewhat, but have the black labrum. 



This species is very close to brevHineata Jac, from Bugaba and 

 Bogota ; the present species is, however, smaller, and the Mapiri form 

 has the thorax very obsoletely foveate at the best, the antennae are more 

 wholly fl.ivous, and the labrum is always black, whereas brevilineata has 

 always a yellow labrum. The antennas has joint two short, 3 one-half 

 longer, 4 long as the two preceding. One of the Mapiri specimens has 

 the humeral stripe elongated to the rear, indicating a form which may 

 connect with the rear spot, but in the type the spot is short and humeral.
