ii2 MEMOIRS ON THE COLEOPTERA. 



ceding, for not only is the characteristic abdominal coloration of 

 the subgenus wholly wanting, but the cephalic carinse and antennae 

 are also unconformable. The mesosternal process is narrowed to 

 apical third of the less separated coxae, its apex much narrower 

 than usual and separated from the equilatero-triangular metasternal 

 projection by a much less abbreviated interval. The type is a 

 female. 



Anatheta n. subgen. 



The body is here almost parallel, with a great development of 

 the prothorax, of which the hypomera are horizontal but warped, 

 in such a way that a small part near the coxae is visible from a lateral 

 viewpoint, as in the preceding divisions of this group. The sterna 

 are concealed in my two unique types, but the hind tarsi in the first 

 are long, the basal joint elongate, though evidently shorter than 

 the second. The two specie? which are placed under this name are 

 of peculiar appearance; the first may be regarded as the type. 



Sableta (Anatheta) planulicollis n. sp. Subparallel, unusually depressed, 

 dull in lustre, the minute sculpture dense and the fine punctures close, the 

 latter strong, asperate and close-set on the more shining abdomen, where the 

 reticulation is moderately coarse and somewhat transversely wavy; color 

 testaceous, the head blackish, the elytra very faintly more flavate, the ab- 

 domen blackish, with the apex and the fine apices of the first three tergites 

 pale, the legs pale; pubescence abundant, pale, moderately short but coarse; 

 head large, slightly transverse, subquadrate, parallel, the eyes at their own 

 length from the base or more, the parallel and feebly arcuate tempora behind 

 them equally prominent, the carinae fine, not quite entire; antennae pale, 

 only the first six joints remaining in the type, the second much longer than 

 the third; prothorax very moderately transverse, distinctly wider than the 

 head and only just visibly narrower than the elytra, parallel, the sides only 

 very slightly arcuate, rounding at apex, the obtuse basal angles slightly 

 blunt, the surface unimpressed; elytra not much abbreviated, parallel, not 

 sinuate at the apices, infumate toward the scutellum but not externally, 

 the suture a third longer than the prothorax; abdomen narrower than the 

 elytra, perfectly parallel, the fifth tergite pale except basally and much longer 

 than the fourth. Length 2.5 mm.; width 0.58 mm. Kansas (Meade), 

 Knaus. 



The distinctive features of this species are the rather depressed 

 and parallel form, coloration and dull lustre, as described above. 

 The type seems to be a female. 



Sableta (Anatheta) curata n. sp. Nearly parallel, more convex, slightly 

 shining, the fine punctures scarcely distinct anteriorly, dense and asperate 

 on the elytra, numerous but feeble on the abdomen, where the micro-reticu-
