The Kdkerlacs are nocturnal. They are great devourers, and gnaw 

 even leather, shoes, &c. The name Blatta (from pXairreiv, to injure) occurs 

 already amongst the ancients ; yet probably it signified other insects. The 

 female lays her eggs heaped into separate, little masses distributed in 

 cells; see GCEZE, NaturforscJier, xvn. s. 183 189, Tab. IV. figs. 1619. 

 BATHKE has communicated his observations on the development in the egg 

 in Blatta germanica in Meckel's Archiv /. Anat. u. Physiol. vi. 1832. s. 371

Anaplecta BURM. Elytra coriaceous, with veins eminent. Pos- 

 terior wings elongate, reflected at the apex. 



Species small, American. 



Family XLIII. Forficularice. Tarsi with three joints. Elytra 

 subcrustaceous, not reticulate, abbreviate, truncated, incumbent on 

 back, placed in contact by a straight suture. Posterior wings mem- 

 branous, partly folded in longitudinal rays, partly transversely, 

 covered by elytra. 



The insects of this family make the transition from the Orthoptera 

 to the Coleoptera. LINN^US counted them with these last, as did 

 also STRAUS amongst more modern writers. LEACH and KIRBY 

 form a distinct order of them, under the name of Dermaptera 

 (Transact, of the Linn. Soc., Vol. XL 1815, p. 87); this name,
