^J TUS CANADIAN ENTOMOLOGIST. 



apex of the elytra, with joints 3 and 4 nearly equal ; thorax transverse, 

 margined, all the angles acute, sparsely, finely and evenly punctate. The 

 elytra are slightly dilated at rear, just a trifle more than in prodiga Er., 

 and not as much as in dimidiata Baly. The rear tibiae are rather darker 

 than the others. The only one of its large allies having a black scutel is 

 prodiga Er. 



D. haenschi, nov sp. 



Head rufous flavous ; mouth-parts piceous ; front carinate ; antennae 

 black, with extreme base rufous. Thorax transverse, shiny, rufous flavous 

 bifoveate, depressed, with all the angles prominent and a few scattered 

 punctures; scutel rufous; elytra dilated behind, thickly and almost 

 rugosely punctured, especially behind ; yellow, with the rear half black. 

 Below, thorax and mesosternum yellow, remainder black, legs black, with 

 base of femora rufous. Length, 5)^-6 mm. 



Type, Balzabampa. Ecuador (R. Haensch) ; also Sn. Inez, 

 Ecuador. 



Belongs to sec. M, and comes nearest to atrivetitris Jac, from 

 Ecuador, but is easily distinguished by the black legs. 



The antennae are long and slender, and reach nearly to the tip of the 

 elytra. The Sn. Inez example is much less rugosely punctured than the 

 type. 



D. marcapa, nov. sp. 



Head, thorax, antennae, scutel, rear half of the elytra, body beneath 

 and legs black, with a faint tinge of green on the thorax; anterior half of 

 the elytra bright rufous ; thorax with three deep fovea, and distinctly 

 though sparsely punctate ; elytra thickly and coarsely punctured, becoming 

 obsolete at the rear. Length, 7 mm. 



One example, Peru, green label (Callanga ?), Jacoby collection. 



This species should be placed in sec. M, though the form is more like 

 that of some of the species of sec. L. Head with carinate front and hairy, 

 especially in front of the eyes ; thorax strongly transverse, margined, with 

 oblique lateral fovea, the rear round and just in front of the scutel ; the 

 elytra only slightly dilated behind. The antennae are about three-fourths 

 the length of the elytra, and joint 3 is not quite as long as 4. The extreme 

 base of the femora is piceous. The tibiae are noticeably covered with 

 sericeous hairs.
