CETONIIN^E 369 



close-set variolate foveae, densely placed near the side margin; disk 

 of the elytra flat, with very elongate foveae, the sides nearly vertical 

 and with coarse variolate punctures; pygidium with coarse variolate 

 punctures; under surface coarsely, sparsely punctured; legs broad 

 and flat, sparsely punctured on the under side, smooth above; 

 anterior tibiae bidentate apically, the middle and posterior with the 

 outer edge acutely bidentate near the tip; tarsi cylindric, slightly 

 compressed, shorter than the tibiae. Length 13 mm. Arizona. 

 [ Crem. planipes Horn] planipes Horn 



Three of the above species, opacula, spinifer and planipes of Horn? 

 are unknown to me and the descriptions here given are derived 

 directly from the originals; there is probably some kind of an 

 emargination outside of the acute hind angles of spinifer, analogous 

 to that so well developed in saucia, quadricollis and setosifrons, 

 but no such abrupt sinus is indicated in the published descriptions. 

 All the species are very rare, excepting saucia, and even that is 

 not over abundant in collections. 



Group II. 

 Subgenus Anatrinodia nov. 



Although apparently intermediate between the preceding species 

 and Cremastocheilus in many respects, and with curtailed pronotal 

 sulci, there are so many peculiar characters pertaining to the unique 

 type of this group, such as the remarkable abdominal structure, 

 that it evidently should be considered as at least subgeneric in 

 value. The hind angles of the prothorax seem at first to be very 

 different from those of saucia and more nearly as in the angularis 

 section of Cremastocheilus, there being a very slight oblique impres- 

 sion delimiting them from the lateral sections of the surface, but 

 on viewing these angles from the sides obliquely below, the emar- 

 gination filled with fulvous setae is observable, though wholly 

 concealed from above. The type may be described as follows: 



Body oblong, parallel, black, in great part opaque above and still more 

 opaque beneath; sparse yellowish hairs of the upper surface very 

 moderate in length, numerous on the abdomen and on the sterna 

 medially; head large, feebly biimpressed on the upper surface and 

 with small sparse punctures, the sides over the antennae slightly 

 prominent; eye-canthus not prominent as it is in the preceding group, 

 anterior slope shallow and gradually formed, the clypeus much 

 wider than the head, truncate, slightly reflexed medially and broadly 

 deplanate and obtusely angulate at the sides; prothorax two-fifths
