sliia consists of two sliort, iK'taclieil, bent stria'; the nicta- 

 ^«tt•r^llm is lati'ially wiilcly and inicroscopically stiinoso, with 

 a shallow iu;;ose sculi)ture ; the anterior tihiie arc 4-5- 

 ilcnticulatc. 



The form of the ni(>so-metustenial transverse stria connects 

 this species with /. elonijatus.

AIlCROLOMALUS, gen. nov. 



This genus is established to receive species hitherto 

 included in Paromalus. The body is somewhat cylindrical 

 and elongate, but not much depressed as in the type of the 

 genus I'arcvHilus {comp/anattts, Panz.), and the form of the 

 prosternum is on a ditierent plan. The ])rosternum is with- 

 out stri;e antl the keel is narrowed anterioily and not much 

 flattened out, the metasternum throughout its length is 

 relatively more narrow, see Hg. 6. 



The species are Jfavicornis, paraUelepipedns, Ilcrbsf ; 

 cinineus, verHalis,\je\v.;Jilumjliii'\t.; sculjitipectus, Mars.; and 

 t^in/pUciaternuji, iSch. M. sculplipeclus^ from Java, I only 

 know by description ; the other species are from the north- 

 temperate zone of the Old World.
