DESCRIPTIONS OF NEW SPECIES. 131 



of the body, moderately stout, and not serrate, with the 3d joint 

 equal in length to the 4th, but a little more slender.* 



* Several of the genera of Cistelidas, now recognized by me as repre- 

 sented in North America, are not mentioned in the table of genera on p. 

 244 of the Classification of Coleoptera. The following table should be 

 substituted : 



A. Mandibles emarginate at tip (truncate in Stenochidus) ; 



a. Body Upiform, thorax subquadrate, narrower than the 



elytra, which are elongate, and deeply striate ; pe- 

 nultimate joint of tarsi lobed. UPINELL2E. 



This group is represented by Stenochidus, which 

 differs from the European Upinella by the mandibles 

 less emarginate at tip, and the last joint of maxillary 

 palpi comparatively much longer, the external side 

 being nearly twice as long as the basal side. 



b. Body oval, thorax widest at base, with basal angles 



distinct. CISTEL^. 



* Penultimate joint of tarsi lobed beneath ; 

 Last joint of maxillary palpi with the apical side 



longest. ALLECULA. 



Last joint of maxillary palpi with the apical side 

 nearly equal to the external (hind angles of 

 thorax nearly rectangular.) HYMENOBCS. 



** Tarsi not lobed beneath ; 



Last joint of maxillary palpi elongate triangular. CISTELA. 

 Last joint of maxillary palpi broad triangular; 



Third joint of antennae nearly equal to the 4th ; 

 Anterior tarsi as long as the tibiae ; antennae slender. ISOMIHA. 

 Anterior tarsi shorter than the tibiae ; antennae stout. MYCETOCHAKES. 

 Third joint of antennas much shorter than the 4th 



(6th ventral segment visible) ; 



Antennae strongly serrate, 2d and 3d joints equal. CHKOMATIA. 

 Antennae elongated, not serrate, 3d joint longer 



than 2d. CAPNOCHROA. 



B. Mandibles acute at tip ; 6th ventral segment visible. CTENIOPI. 



Hind coxae divided by a transverse groove ; the pos- 

 terior portion larger, flat, with the hind edge 

 acute ; 



Anterior tarsi elongated, deformed in the male. ANDBOCHIEUS. 



Hind coxae divided into two nearly equal portions ; 



Antennae slender, hind angles of thorax rectangular. CTENIOPUS. 



The species of Cistela are easily recognized by the last joint of the 



maxillary palpi being elongate triangular, the apical side much shorter 



than either of the other two in the first division, equal to the basal one in 



the second. They form two divisions ; in the first (as in the European
