WICKHAM: new MIOCENE COLEOPTERA from FLORISSANT. 491 

 CORPHYRA CALYPSO, Sp. nOV. 



Plate 16, fig. 3-4. 



Form moderately robust. Head small, eyes destroyed but the 

 orl^its indicate that they were of good size. Antenna only slightly 

 serrate, slender but not very long, the basal joints in poor condition, 

 the intermediate ones about one and one half times as long as wide. 

 Pro thorax suborbicular, sculpture obliterated. Elytra four times as 

 long as the prothorax, sides subparallel, apices bluntly rounded, sculp- 

 ture very obscure, apparently a confused close punctuation or rugosity, 

 two or three longitudinal lines showing on each which are probably 

 due, in part at least, to underlying wing veins. Fore leg, the only one 

 showing, rather short and quite stout. Length, as preserved, 8.50 

 mm.; to elytral apex, 8.40 mm. ; of elytron, 5.70 mm. 



Described from one specimen.

The form, size, and, as far as showm, the sculpture, are those of 

 Corph^Ta. The antennae agree very well if we assume that the third 

 joint is broken off in the middle and that the break immediately pre- 

 ceding the first of these sections represents the place of the second 

 joint. The small head makes it unlikely that the insect is a meloide. 



MELOIDAE. 

 Tetraon^x mixuscula, sp. nov. 

 Plate 16, fig. 5. 



Preserved in profile. Form moderately stout. Head large, finely 

 punctate and clothed with sparse blackish hairs. Antennae showing 

 the distal six joints which increase in length apically and are sub- 

 moniliform. Prothorax higher than long, surface shining like that of 

 the head, punctuation fine and sparse, giving rise to long dark hairs of 

 greater length than those on the head. Elytron finely, sparsely punc- 

 tured and hairy, the hairs shorter than those of the prothorax or less 

 well preserved. Legs rather stout and clothed with sparse dark hairs. 

 Abdomen and side-pieces of the meso- and metasternum obscurely 

 punctate and nearly smooth except that a few hairs may be seen in
