This division (Ei poda of Latkkiu-*:) ciiilinicos a grouji ol' insects whose bodies are short, 

 oval, thick, and hemispheiical (for an example, see PL xiv, 1 1). The thorax is sometimes 

 angular, uniting closely with the base of the elytra, and forming with them a circle or a 

 broad oval. The head is short, and concealed ; the antenna? shorter than the Ixxly, filiform. 

 The insects are usually small, Ijut their colors are lively and brilliant, though only a few 

 are metallic in this climate : the Eiimo/ptis is one of the brightest. They arc vegetable 

 feeders in the larva and perfect stales, and some of them are highly injurious ; tlie Haltica 

 destroying the tiuiiip crop, and the Criocesris the asparagus plant. 



Crioccrida?. 



TiiK body is oblong in this family, and the hindlegs are often thickened for leaping. The 

 he;id ami th irax arc narrower than the abdomen. The antennre are filiform, or only slightly 

 thickened at the tips : thoy are inserted Ix'fore the eyes, which are prominent. Found 

 upon leaves and stems of trees. 



Crioceris ( or Lema ) trilintata ( Oliv,), is a yellow insect about one-fourth of an inch 

 long; the elytra with three black lines, one along the midiile of the back, and one on 

 each side. It belongs to an extensive division which contains man.> species that are de- 

 structive to ganlen vegetation, genirally devouring the leaves, both in the larva and the 

 perfect state. Tin- si)ecies here cited attacks the foliage of the potato, and Dr. Harris 

 recommends brushing them into shallow vessels of salt and water, or vinegar.
