Besides the likeness in construction of the mouth-parts this genus 

 has this in common with Thiasophia , that the head is not constricted be- 

 hind, and that the first Joint of hind tarsi is shorter than the claw- 

 joint. But in Sticho.'^lossa the body is slenderer, more convex, and most 

 often more rfilisteninj than in the preceding genus; antennal outer joints 

 (6-10) are not compact, but rather open jointed; hind corners of prono- 

 tum are less pronounced, obtuse-anf^ulgr; first three-four free dorsal 

 joints of abdomen are more deeply depressed at base, and the first three 

 ventral joints are feebly, yet distinctly impressed or transversally 

 grooved at base. 



The species live under bark of trees and stubs, which are attacked 

 by bark beetles, at outflowing tree sep, and one single species in compa- 

 ny with ants. 



Of the three species, which are found distributed in forth and Midd- 

 le Europe, and which also belong to our fauna, one, semirufa, is by Kraatz 

 referred to genus Stenoglossa , the two others, corticina and prolixa , to 

 Ischno.^loGSB ; of these latter, corticina 1g by ihomson treated as a sepa- 

 rate genus, Dexlo.gya . The separating characters are however not import- 

 ant, and permits very well that all three species be placed under Sticho - 

 glossa , but each In its subgenus.
