Since the specimen is in reverse, the granules and raised lines noted 

 in the description represent corresponding punctures and striae J

 American species of the genus although these furnish among them-

MELANOPHILA HANDLIRSCHI Wickham. 



This seems to be the most common buprestid of the Florissant 

 shales The present collection contains six specimens, one with 

 counterpart, No. 2,476-2,482 M. C. Z. (No. 406, 502, 6,388, 8,404, 

 12,488, 16,356 and 16,357 S. H. Scudder Coll.). The first noted exam- 

 ple is remarkable for its beauty and the perfection of preservation. 



MELANOPHILA COCKERELLAE Wickham. 



Represented by two specimens, one of which, No. 2,474 M. C. Z. 

 (No. 15,077 S. H. Scudder Coll.), is 2 mm. longer than the type, 

 while the other, No. 2,475 M. C. Z. (No. 5,727 S. H. Scudder Coll.), 

 exceeds the original measurement by less than 1 mm. 



ANTHAXIA EXHUMATA Wickham. 



One poor specimen, No. 2,472 M. C. Z. (No. 1,855 S. H. Scudder 

 Coll.). 



CHRYSOBOTHRIS SUPPRESSA, sp. nov. 

 Plate 3, fig. 4. 



Preserved in ventral aspect and therefore not displaying important 

 features of sculpture. Outline similar to that of the recent C. floricola. 

 Prothorax hardly differing in width at base and apex, sides almost 

 straight, flanks with moderately large, rounded, shallow, often con- 

 fluent punctures, the prosternum with the punctuation so strongly 

 confluent as to form transverse grooves. Meso- and metasternal 

 side-pieces sculptured about like the prothoracic flanks, the abdominal 

 punctures finer and more widely separated. Margin of last ventral 

 not serrulate. Anterior tibia curved but not visibly enlarged at apex 

 though the preservation is not good enough to be sure. Length,
