specimens are in hand from the state of Washington. It is 
readily recognized by its short vertex, elongate elytra, with the 
central anteapieai cell divided, and the presence of six round 
black dots, a pair on the anterior margin of each, vertex, pro- 
notum a.nd scntellnm; color, fuscons maculate. Ultimate ven- 
tral segment of the female narrowing posteriorly, margin twice 
indented, including a median obtuse tooth, outer angles round- 
ing; male, ultimate segment slightly, angularly emaginate; 
valve short, obtusely angled; plates narrow, acutely pointed, 
equaling the pygofers. 
Larv93: broad, stout-bodied, with blunt, obtusely rounded 
heads; color yellow, with a broad, black margin behind the 
eyes. 
The life- hi story of this species has already been given. 
Further observations during the past season confirm the idea 
of two broods as follows : Larvae appearing about the first of 
May and maturing before the middle of June; adults from the 
first of June to the middle of July; the second brood of larv^ 
appearing before the middle of July and mostly matured by the 
third week in August, adults again from the second week in 
August on through September. 
This species has a wide range in food habit and consequent 
variability in its life -history. The limits given above are for 
blue grass broods, where it is under nearly constant conditions 
and seems to be reasonably definite in its appearance. Its 
occurrence on annuals would be materially affected by the date 
of their appearance.

This pretty little species has also, probably, a very wide 
range, though only reported as yet for Mississippi. It also 
occurs at Ames. 
Adults measuring about 3 nim. , with a bluntly produced ver- 
tex, sides sharply concave, elytra slightly longer than the 
abdomen, flaring; central anteapieai cell divided, color testa- 
ceous brown, with the anterior portion of the vertex and ner- 
vures of the elytra light; four dark points on anterior margin 
of vertex, front and venter dark; male plates short, together 
nearly circular in outline. 
This species was taken at Ames in June, but no determina- 
tion as to its life-history has been made.
