L.foliaceus, or straight as in L. semiamplexus, or rounded in- 

 curved as in L. dentipes. 



The female specimens seem most of them to correspond with 

 this in size, and came along with them and in equal numbers; 

 therefore I have presumed them to be the female of this, rather 

 than of the typical L.foUaceus. Fig. 2 represents one of these 

 females. They are the L. xanthomelas of Schonherr.

Allied to L. immersus. Elytra in the male distinguished 

 by a prominent dorsal umbo. The apical black patch extends 

 over fully the half of the elytra, and embraces the umbo. The 

 suture is incm*ved and slightly sinuate at the apex, and has 

 the angle blunt. 



Only one specimen was received. 



4. Lycus semiamplexus. PL IX. fig. 6. 

 Niger, supra flavus, elytris margine posteriore nigro. L. im- 

 merso minor, textura Iseviore ; ^ macula apicali nigra mar- 

 ginem posteriorem elytrorum amplectente et super suturam 

 breviter ascendente, sutura angulis apicalibus rectis.

(J . Still smaller than L. immersus^ and very constant in size ; 

 rounder behind than it. The reticulations are finer, smaller, 

 and the texture rather closer ; and the form of the black apical 

 mark on the elytra is different, extending in a well-defined 

 narrow band more than halfway along the outer margin, and 

 also encroaching in an oblong patch on the suture, as shown 

 in PL IX. fig. 6 ; in other respects the colom-ing is the same. 

 The suture is straight, and its angle right-angled and a little 

 rounded or blunt at the point (fig. 6) . 



I have no doubt that this is distinct from any of the pre- 

 ceding ; the size, distribution of colour, straightness of the 

 suture, and fineness of texture are very constant. I have, 

 however, no certainty about the female.
