 (Continued from page 16.) 

 D, peckii^ nov. sp. 



Yellow; head, intermediate joints of the antenna?, scutel, pectus, 

 tibise and tarsi black ; elytra smooth, shining yellow, each with a large 

 quadrate black patch at the base and a large circular black spot at the 

 apex, in the middle of each a round yellow spot. Length, 5^^ mm. 



One example. Manatee Dist., Brit. Honduras, Dec. 6, 1909. 

 Collected by Mr. Peck. 



Head with fovea small and abrupt ; antennae a little more than half 

 the length of the body, joint 2 short, 3 one-half longer, 4 equal to two 

 preceding; i and 9-10 and base of 11 pale yellow, 2-3 cloudy, the rest 

 daik. Thorax pale flavous, smooth impunctate, faintly depress'ed behind 

 and at the middle, and obsoletely bifoveate ; elytra very slightly dilated 

 behind, smooth, shining, faintly and finely punctulate, longitudinally sul- 

 cate, when looked at from behind at a certain angle obsoletely, 

 the basal black patches join at the suture, each is convex towards the apex 

 and reaches nearly the middle of the elytra, but does not attain the 

 lateral edge ; the apical patch oblong circular, nowhere attaining the edge 

 or suture. 



Very close to bioculata Bow., but with three, in place of two, upper 

 joints of the antennas light, thorax wider and more indefinitely foveate, 

 elytra much more sparsely punctured, and colour of markings dull black 

 in place of blue or cyancous. 



D. coIunibie?isis, nov. sp. 



Head, tibiae and tarsi black, antennae more than half the length of the 

 body, joints 1-3 and 9-10 flavous, rest piceous, thorax rufous (like 

 varicornis Jac), deeply bifoveate, and sometimes an indication of a third 

 just before the scutel, which is piceous; elytra yellow^ strongly plicate, 

 with a blue-black annulus at the base (often broken), and a curved fascia 

 behind the middle, not attaining either edge (often broken) ; between 

 these blue marks is a sufi"ased rufous-orange band, and the tip is the same 

 colour, abdomen and femora yellow. Length, 5-6 mm. 



Type Columbia, also Ibague, Columbia (Fr. Claver) 4 var., Calif., 

 Columbia (Rosenburg), (Venezuela, Mocquerys ?).
