476 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 



Elytra nearly four times as long as the prothorax, minutely punc- 

 tulate and clothed like the rest of the upper surface, apices bluntly 

 pointed. Legs in very poor condition but apparently of normal 

 thickness for the genus. Length, to elytral apices, 10.15 mm.; of 

 elytron, 7.50 mm. 



Described from one specimen. 



Type No. 2,634 M. C. Z. Florissant, Col. (No. 11,266 S. H. 

 Scudder Coll.). 



Easily distinguished from either of the other two Florissant species 

 by the much greater size which slightly exceeds that of the average 

 specimen of the recent T. canadensis. 



HALTICA RENOVATA, sp. nov. 

 Plate 13, fig. 2. 



Form oblong-ovate, moderately stout. Head showing no characters 

 except those exhibited by one antenna which is incompletely preserved 

 but the five joints that remain, with the less defined remnants of two 

 more, are slender as in recent species of the genus. The entire upper 

 side is hidden in the type, but the elytral epipleural margin does not 

 indicate striation nor heavy punctuation, and from this fact and the 

 lack of sculpture showing through the body we may infer that the 

 surface was merely finely punctulate or smooth. Anterior coxae 

 large, probably not separated for their full length by the prosternum. 

 Under surface of the trunk, including the abdomen, with no conspicu- 

 ous sculpture. Hind legs with strongly swollen femora, the tarsi 

 crossed so as to hide their articulations. Length, 5.25 mm. 



Described from one specimen. 



Type. No. 2,635 M. C. Z. Florissant, Col. (No. 7,296 S. H. 

 Scudder Coll.) . Probably the same species is represented by No. 2,636, 

 2,637 M. C. Z. (No. 7,736, 3,507 S. H. Scudder Coll.). 



It is possible that this is not a true Haltica but the general agreement 

 is sufficiently close. 



SYSTENA FLORISSANTENSIS Wickham. 



To this species probably belong four specimens, No. 2,638-2,641 

 M. C. Z. (No. 413, 3,430, 8,933, 9,615 S. H. Scudder Coll.). Like 

 the type, they show the underside only.
