14. Derolus spurius spec. nov. 



(?. Black, legs and antenna brownish brick-red ; head and protborax maculated 

 with a golden pubescence ; base of antenna also with yellow pubescence ; rest of 

 liody pubescent grey, the pubescence silky, with a yellowish tint, changing in patches 

 from brown to grey according to light. 



Head and antenna essentially as m femorellus, the antenna longer and a little 

 thinner. Protliorax longer than in that species, differently sculptured ; subapical 

 sulcus deep, curved backwards in middle ; close behind it there begins a mesial 

 groove which soon divides in two branches, wbicb are connected again by the 

 snbbasal sulcus, thus encircling an elongate ovate area ; the grooves irregular ; the 

 lateral portions of the thorax also divided by a deep, obliquely longitudinal, and a 

 transverse groove ; besides these grooves there is the ordinary plication, which is 

 very irregular. Elytra punctured in basal half, smooth in ajiical half ; apex 

 truncate, with both angles dentate, but the outer tooth broad and obtuse. Pro- and 

 mesosternnm as im fetnoreUus. 



Ijength, 19 mm. ; elytra, 12 mm. ; breadth, 4^ mm.

15. Derolus parus spec. nov. 



?. Black ; pubescence of bead and protborax yellowish, sparse, of rest of body 

 and legs olive-grey. 



Depressed anterior part of frons almost smooth, with very few punctures ; no 

 longitudinal sulcus between antennae, mesial line somewhat raised on occiput ; 

 antennal tubercles margined ; upper lobes of eyes nearly as close together as in 

 femordlus. Antenna as long as body ; scape very short, not narrowed towards 

 base, rugate-punctate ; segments 3 and 5 longer than in fcmorellus. Protborax 

 longer than in spurius, with a similar divided groove on disc, but the plication more 

 regularly transverse. Scntellum semicircular, shorter than in either spurius or 

 femordlus. Elytra evenly olive-grey, punctured all over, the punctures very 

 shallow in ajiical half, apices rounded together, not truncate, sutural angle not 

 dentate. Prosternal process truncate-tuberculate, slightly convex along middb:, 

 ('arinae of femora obsolescent.

 uppersidc golden-tawny, witli dark reflections on elytra. Head finely punctured ;
