DENDROBLATTA" new genus 



A member of the Blattellites, but apparently not closely related 

 to any of the previously known genera except Mareta Bolivar. 

 The combination of strongly deplanate head, verj' narrow inter- 

 space between the eyes, very wide and deplanate pronotum, the 

 presence of a gland on the seventh dorsal abdominal segment of 

 the male, elongate limbs and peculiar armament of the cephalic 

 femora is diagnostic of the genus. 



Generic Characters. — Form deplanate, fully alate in both sexes. 

 Head very strongly deplanate; eyes narrowly separated in both 

 sexes; lateral margins of head ventrad of eyes strongly conver- 

 gent to the base of the mandibles; maxillary palpi elongate. 

 Pronotum broad, tranverse, with broad lateral margins which 

 are but little deflected. Tegmina with discoidal rami and ulnar 

 vein obUque, former numerous. Wings with intercalated tri- 

 angle very small, elongate and narrow. Seventh dorsal abdom- 

 inal segment of male with a decided gland mesad. Supra-anal 

 plate of male strongly transverse; cerci very elongate, deplan- 

 ate dorsad, ventral surface extremely hirsute and with each 

 segment convex. Limbs extremely elongate; cephalic femora 

 with ventro-cephalic margin armed on distal three-fifths with a 

 close set row of minute chaetiform spines, ^^ the series terminated 

 by two elongate spines distad; distinct arolia present. 



Genotype. — Dendrohlatta sobrina new species. 



This very striking genus is unique in quite a few morphological 

 features, while its coloration and habits are as distinctive as its 

 structure. The closest affinity of Dendrohlatta is with Mareta 

 Bohvar, from which the narrower eye interspace, the presence 

 of the dorsal gland on the abdomen of the male, the more cor- 

 neous tegmina and the much more elongate tarsi readily separate 

 the new genus. 



" This generic name has been given in allusion to the arboreal habits of the 

 species, which will be discussed in detail at a later date. 



^^ The proximal two-fifths of the ventro-cephalic margin of the cephalic 

 femora is rarely unarmed, occasionally supplied with one or two small spines 

 and frequently with four or five spines.
