The female.is rather larger than the male, and lias the hind

30. Cryptohypnus humilisj n. sp. 



C. subdepressus, tenuissime pubescens, uiger, antennis pedibusque 

 testaceis ; prothorace lateribus rotundatis, ante basin constricto,

Though extremely similar to the preceding species, this 

 may be readily distinguished by the more prolonged hind 

 angles of the thorax. The differences between the sexes seem 

 to be very slight : the female is rather larger, and has the 

 thorax a little more dilated at the sides.
