I give the above generic name to two new species allied 

 to Cri/ptubium with some reluctance, because that genus 

 contains a variety of forms, several of ■which, in one or 

 more respects, approach these insects ; the very narrow 

 neck by which the head is articulated with the thorax is, 

 however, not met with in Cryptobium.
