DESCRIPTIONS OF NEW SPECIES. 123 



have placed in the tribe Ulomini cannot be associated with 

 Diaperini in consequence of the epistoma being somewhat pro- 

 longed, entirely concealing the membrane at the base of the 

 labrum, and of the middle coxae being inclosed so as to render 

 the trochantin invisible. 



Duval, in separating the allies of Diaperis from those of Uloma, 

 has considered the form of the tibia? as of primary importance ; 

 the close resemblance in all other characters of value between 

 our genera shows that character is not to be relied on ; and 

 I prefer returning to the one established by Lacordaire, derived 

 from the form of the middle coxa? ; adding to it the prolonged 

 epistoma, which conceals the clypeus. 



ULOMA KEDT. 



399. U. intberbis. Ovalis modice elongata, picea nitida, capite 

 antice luuatiin impresso et inter oculos trausversim impresso, thorace 

 punctulato, longitudine sesqui latiore, a basi prsecipue ante medium 

 angustato, lateribus marginatis late rotundatis, basi vix bisinuata, irn- 

 marginata ; elytris striis punctatis, interstitiis obsolete punctulatis ; 

 tibiis anticis 7-9 denticulatis ; mento trausverso, late coiicavo, maris 

 l?evi, feminse fortiter punctate. Long. -33 -36. 



An abundant species from New York to Kansas. This species 

 (by description) differs from the European U. perroudi by the 

 thorax being narrowed from the base the sides even near the hind 

 angles not being parallel. 



The male has the menttim somewhat more cordiform than the 

 female, broadly concave, and not punctured ; the thorax is less 

 rounded on the sides, less narrowed in front, and has a distinct 

 but vague transverse impression near the tip. 



It is evident that the species of Uloma are more numerous than 

 was formerly believed, but it is quite possible that some of the 

 species here described may be identical with those already known 

 from distant parts of the globe. U. impressa, which has been 

 commonly considered as U. culinaris, introduced in articles of 

 commerce, differs from the European species described under that 

 name by the medial plate of the mentum being entirely glabrous, 

 angulated at the sides, slightly concave and feebly punctured at 

 the middle, sulcate at the sides in the male ; flatter, strongly punc- 

 tured, and more deeply sulcate each side in the female.
