of feeding and habits are similar to those of marevagans and very 

 often the foliage is completely riddled. 



Egg. — Length 0.7 mm. Width 0.21 mm. Except for its smaller 

 size it is similar to the egg of Haltica marevagans. 



Full Grown Larva. — Length 4.5 mm. Width i mm. Somewhat 

 like that of H. marevagans in general appearance and number and 

 arrangement of tuberculous spots. However, the following differ- 

 ences are to be noted: the larva is smaller; shagreening is finer; 

 ground color is lighter, being yellowish green; the spots also are of 

 a lighter brown and differ in some cases in outline; the spiracular 

 spot is closer to the two dorsal lateral spots above it and more in be- 

 tween them; when the spot below the spiracular spot is compared 

 with the spiracular spot, a greater difference in size will be found in 

 fuscocenea than in marevagans; the median line dividing thoracic 

 plates and median thoracic spots is wider in fuscoccenea than in 

 marevagans. 



Pupa. — Length 2.8 mm. Width 1.4 mm. Light yellow; smaller 

 than that of marevagans; spine-like hairs on head similar to those of 

 marevagans; prothorax bears a single spine-like hair on posterior 

 margin instead of a pair as in marevagans and a dorsal pair anterior 

 to median, dorsal pair; meso- and metathorax bears a pair of median 

 ones and a single one each side of these ; abdominal hairs placed 

 similar to those of marevagans; extremity of abdomen terminating 

 in a pair of stout spines which are more elongate than those of mare- 

 vagans and slightly incurved at the tips. 



Adult. — Haltica fuscocrnea. This was described by Melsheimer 

 in 1847 (Proc. Phil. Acad. Nat. Sci., Ill, 165). The following re- 

 description is by Horn (Trans. Amer. Ent. Soc, Vol. XVI, p. 229) : 

 " Oblong oval, moderately shining, olivaceous green, antennse and 

 legs rufotestaceous. Antennse a little longer than half the body, 

 joints 2-3-4 gradually increasing in length. Head finely alutaceous, 

 a faint transverse groove between the eyes in which are a few indis- 

 tinct punctures, frontal carina broad and obtuse, the tubercles small. 

 Thorax transversely subquadrate, very little wider than long, not 

 narrower at apex than base, sides very feebly arcuate, margin very 

 narrow, slightly thickened at the front angles, disc convex, the ante- 

 basal impression fine, but moderately deep, extending nearly from 

 side to side, surface finely alutaceous and with very minute sparse
