with that species without an exainiuation of the anteimje. The 

 sexual characters are not very different, except that in decipiem the 

 middle truncate portion of the last ventral is slightly more prolonged. 

 Occurs at Yreka, Cal., collected by Mr. Wm. Duenkel.

This new name is proposed for a species described posthumously 

 by Dr. LeConte as Agelastica bico/or. The characters are those of 

 Luperus, excepting that the tibise are all without spurs. The first 

 joint of the hind tarsus is nearly as long as the three following 

 joints together and slender. The anterior coxse are very narrowly 

 separated, the cavities open behind. 



The length of the first joint of the hind tarsus excludes it from 

 association with Agelastica, and by that character, and the absence of 

 tibial spurs, it approaches Scelida. From the latter genus it is sepa- 

 rated by its broadly oval and convex form and by the front cox^e 

 being narrowly separated by the prosternum. 



T. bicolor Lee, Trans. Am. Eut. Soc. xii, November, 1884, p. 28.— Form 

 rather broadly oval, convex, body and legs honey-yellow, elytra black, surface 

 shining. Antennae piceous, the four basal joints pale. Head smooth. Thorax 

 more than twice as wide as long, slightly narrower in front, sides very slightly 

 arcuate, angles rather obtuse, disc convex, smooth and shining. Elytra oval, 

 broader behind, convex, disc slightly impressed behind the scutellum ; surface 

 punctate, regularly over the entire surface, the punctures not coarse nor close. 

 Body beneath smooth, with very sparse pubescence. Length .21 inch. ; 5.5 mm. 



The only specimen examined is the type described by Dr. Le- 

 Conte under the genus Agelastica, a female, in which the last ventral 

 is oval at tip and entire. 



The species resembles very closely the figure given by Jacoby, 

 Biol. Cent.-Amer. vi, pt. i, pi. 34, fig. 4, of Meiacycla robusta, and is 

 about the same size. The latter species seems not to be a Metacycla. 



Collected at Fort Yuma, Cal.
