PODONTIA. 



221 



sinuate with a median lobe, sides straight from the base to beyond 

 the middle, where they bend inwards, the protliorax being thus 

 narrowed in front ; anterior lateral angles produced, the posterior 

 angles are right angles, although they may be rounded or slightly 

 drawn out; surface always uneven, with depressions and elevations; 

 margins all round often thickened and rounded. Scutdlum small 

 compared to the large size of the body, triangular. Elytra broader 

 than prothorax, parallel-sided, rounded at apex ; surface smooth, 

 each elytron with eleven very regular longitudinal rows of 

 punctures, including a scutellar and an extreme marginal row ; 

 interstices smooth and flat, that between the extreme marginal row 

 and the row next within it broader than the others ; epipleura broad 

 at base, narrowing considerablv to the apex. Underside : pre- 

 sternum broadened in front, elevated between the coxae, longi- 

 tudinally channelled, dilated and triangularly excised behind, the 

 apex of the mesosternum fitting into it; anterior coxal cavities 

 closed behind; mesosternum very short with hind margin rounded 

 and excised to receive the front of the metasternum. Legs 

 comparatively short and robust ; anterior tibiae somewhat dilated at 

 the apex, but not emarginate ; middle tibiae distinctly dilated 

 at the apex, where they are channelled on the outer side, the apex 

 with a small sharp spinule underneath; posterior femora dilated 

 more than the other femora, but not so much as in some other 

 genera of the Haltici:n7e, channelled on the underside and having 

 a dentiform expansion about the middle ; posterior tibiae longer 

 than the anterior or middle tibiae, strongly dilated and channelled 

 on the outer side towards the apex, the margins of the channel 

 being densely covered with cilia-like hairs, the external margin 

 raised into an angle at its beginning, the extreme apex furnished 

 at the outer corner with a small sharp spinule ; tarsi large, first 

 segment well developed, second small, third very large, bilobed, 

 fourth long, extending much beyond the bilobed segment, and 

 ending in two strong bifid claws ; the smaller member of each 

 claw is on the inner side. 



The secondary sexual characters in this genus are as follows : 

 in the male (1) the first segment of the anterior and middle tarsi 

 is dilated and convex, (2) the posterior border of the last abdominal 

 sternite has a deep and narrow emargination on each side ; in the 

 female (1) the first segment of the anterior and middle tarsi is 

 triangular but not so dilated towards the base, (2) the posterior 

 border of the last abdominal sternite is not emarginate at all, 

 (3) the dentiform expansion about the middle of the posterior 

 femora is not so accentuated as in the male. 



This is a very homogeneous genus, the species of which are 

 easily distinguishable by their colour-characters.
