tate, sometimes with a faint series of punctiform non metallic foveolse 

 near the suture. 



There is so much variation in the large series I have received from 

 Mr. Crevecoeur in the punctuation and color of the elytra, which vari- 

 ations are duplicated in other Ciciudelidse, that I cannot recognize seri- 

 ceus and pruininus as anything but synonyms. The Kansas specimens 

 are entirely without the row of fovese which begin to appear in Texas 

 specimens thus leading on to the next species.

Resembles the preceding and differs in having a series of green 

 punctiform fovea in a row near the suture, and a few dispersed over 

 the elytra and in having the head and, to a less degree, the thorax 

 o-reenish. This species is apparently confined to the locality stated 

 above and is rare in collections where Beljragei is often placed under 

 this name. The late Mr. Hugo Soltau collected it at Covington, La., 

 in woods on the north shore of the lake by using a lantern. 



CI€II«nEL,A Linn. 



The species of this genus usually live in sunny places, either sandy 

 roads and fields, ocean shores, lake shores, river banks, mud flats, 

 hiding during the night and on rainy or cloudy days in holes dug 

 in the sand, or under bark, stones, dried mud or similar situations. 

 They present a very uniform appearance, the most obvious differences 

 being in size and color. The head is large and the eyes prominent. 

 The thorax varies from cylindrical to a flattened trapezoidal form. 

 The elytra are usually quite convex and subparallel at the sides, 

 while the tips may be rounded or in one group emarginate. The legs 

 are always long and slender. The minor structural characters used 

 in separating the species are drawn from the labrum, the interocular 

 striae of the head, the thorax and the elytral tip ; the pilosity of the 

 body and the punctuation of the elytra are also used. 



The labrum may be either prolonged or short, glabrous or hairy, 

 dentate or simply sinuate in front. When dentate the number of 

 teeth varies from one to three, the teeth vary in position and in 

 magnitude. .The figures show the form of the labrum in several
