NEW SPECIES OF CRYPTOCEPHALUS 
(Coleoptera; Chrysomelidse) 
By H. C. Fall 
Tyngsboro, Mass. 
Cryptocephalus pallidicinctus n. sp. 
Moderately robust. Head black, a quadrate post-clypeal 
area, a small spot posteriorly adjacent thereto, and the en- 
tire inner border of the eyes narrowly whitish yellow. 
Antennae black. 
Prothorax orange red, the extreme apical edge pale yel- 
low, the basal edge very narrowly blackish ; surface 
sparsely feebly and very finely punctate. 
Elytra black, with narrow whitish yellow basal and lat- 
eral margin which at apex does not quite reach the sutural 
angle; striae moderately impressed, nearly as in sanguin- 
icollis, the sutural not reaching the middle of the elytra, 
6th very widely interrupted medially, 7th dislocated at 
basal third. 
Entire upper surface polished and strongly shining. 
Pygidium coarsely punctate, obtusely carinate at middle in 
basal third. Body beneath black; prosternum whitish yel- 
low, with moderate cuspiform lobe in front, the hind angles 
with erect spiniform processes tipped with black. 
Length 4 mm.; width 2.3 mm. 
Palm Springs, California, 3-22-17. A single male. 
This species is nearly related structurally to sanguini- 
collis, but differently colored. It differs further in its more 
distinctly impressed elytral striae, carinate pygidium, and 
smoother elytral interspaces, which show scarcely a trace 
of the fine transverse regulosity usually evident in sanguini- 
collis.
