Female. — Last ventral more broadly aud less deeply triangularly emarjrinate ; 

 claws stouter and more deeply bifid. 



In coiiipari.son with the other vittate species this one has the elytra 

 more finely punctate than any, except, possibly, sexvittata. From 

 the latter species, which it most resembles, it differs in having the 

 middle coxse absolutely contiguous. There is also a distinct subsu- 

 tural vitta in the present species not seen in that. From the next 

 two species it differs not only in the different arrangement of the 

 vittre, but also in the finer punctuation. 



Occurs from Pennsylvania to Florida and Texas.

 Lee, Free. Acad. 1865, p. 217: bilineata Kby., Fauna Am. Bor. iv, p. 220. — Oval, 

 slightly oblong, moderately convex, dull yellow, sparsely clothed with fine, re- 

 cumbent, silky pubescence; thorax trimaculate, each elytron with a subsutural 

 and three discal vittse. Antennse piceous, the basal half paler. Head coarsely 

 and moderately closely punctate, the median line impressed and piceous. Thorax 

 nearly twice as wide as long, narrower in front, sides strongly arcuate, base on 

 each side oblique, hind angles distinct, disc depressed each side with three pice- 

 ous spots as in integra. more or less obliterated ; surface coarsely, but not very 

 closely punctate; elytra scarcely wider behind, humeri distinct but obtuse, lateral 

 mai'giu narrowly explanate, sutural angle obtuse, disc closely punctate, punctures 

 coarse, but varying, finer toward apex, the subsutural vitta rarely reaches the 

 base, the second vitta is oblique and joins the sutural at or behind the middle, 

 the third is often nearly entire, the fourth starts at the umbone and often joins 

 the sutural. Body beneath pale, with piceous melasternum. Legs pale. Length 

 .14 — .20 inch. ; 3.5 — 5 mm. 



The sexual characters do not differ notably from those observed 

 in integra. 



The markings of the elytra vary by obliteration to a great extent, 

 so that at times it may require considerable tact to determine whether 

 a specimen should be referred to this species or notata. When the 

 markings are entirely obliterated, the resemblance to some Monoxise 

 is very great, but the form of the claws, if a female, will enable the 

 specimen to be placed. 



Frequently specimens occur in which the vittfe seem to be elevated 

 and subcostiform, these represent the bilineata of Kirby. 



Occurs in the entire region east of the Rocky Mountains from 

 Canada southward, also in New Mexico. Specimens are before me 

 from California, but it has probably been introduced there.
