Hah. Ecuador {Buckley). A single specimen in the 

 collection of Mr. Fry. Also Mexico and other parts of 

 Central America, where it appears to be common. In 

 most collections. 



This insect is so closely allied to D. hianmdaris, 

 Harold, that it is quite unnecessary to give a detailed 

 description ; the sole point of difference between the two 

 being that in pidchella the thorax is convex and bifoveo- 

 late, whilst in hiannularis it is more or less distinctly 

 excavated and trifoveolate.

Hah. Colombia, Magdalena Eiver. My collection. 



Closely allied to hiannularis, agreeing in the sculp- 

 turing of the thorax, but separated by its larger size, 

 the irregular and coarser punctuation of its elytra, 

 the plicate outer disk, the black tibiae and tarsi and the 

 darker coloration of the antennae. 



Spec. 52. Diabrotica Haroldi, Baly.

Hah. Colombia. Unique in my own cabinet. 



Agreeing in size and in the coloration of its legs and 

 antennae with the preceding species, differing in the 

 smoother surface of the elytra and in the bi- not tri- 

 foveolate thorax.
