punctures. Elytra not wider at base than the thorax, humeri broadly 

 rounded, umbone not distinct, surface distinctly sparsely punctate 

 near the base, smoother at apex. Body beneath piceous with icneous 

 luster; abdomen sparsely punctate. Legs rufotestaceous, the poste- 

 rior femora piceous with jeneous surface luster. Length .12-. 14 

 inch; 3-3.5 mm. 



" In the male the last ventral is truncate at middle, a slight sinua- 

 tion on each side, the middle at apex flattened, the edge slightly re- 

 flexed. This species has rather the habitus of a ChcFtocnoita than 

 Haltica in general. The nearly square thorax, together with the 

 pale antennae and legs v\^ill enable it to be distinguished from polita 

 and all the others of the genus. Occurs from ISIassachusetts to 

 Georgia." 



In New Jersey it occurs from ]\Iay to September and according to 

 Smith (Ins. N.J.) it is especially common on evening primrose along 

 the shore. However, we have found it also common as far inland 

 as the Delaware River in the southern part of the state. It is notably 

 scarcer, however, in the northern sections. 



In the southern counties it appears during the first w'eek of ]\Iay 

 and deposits eggs on the foliage of primrose, usually on the lower 

 surfaces. These are placed as a rule in groups of two or three. The 

 eggs are yellow and covered with a whitish envelope which some- 

 times cracks and falls off. A similar covering is present on the eggs 

 of viarevagans. The life-history in fact appears to be like that of 

 marcvagans. About six weeks are necessary for a complete life 

 cycle. Adults appear about the first of Alay. About the middle of 

 June and again during the first week of August adults appear in 

 numbers. Eggs are again laid at this time and the larvae when full 

 grown enter the soil and pupate. The evidence at present points to 

 the winter being passed in this stage. During the summer pupation 

 requires about ten days.

 Agallia sanguinolenta Prov. 



On July 15 at Lakehurst, N. J., nymphs and adults of this leaf- 

 hopper were observed on evening primrose. It is known as the 

 clover leaf-hopper and usually confines its attacks to clover, alfalfa, 

 cowpeas and vetch. However, it is common in meadow and pasture
