LEPTOCOKISA. 40^^ 



Division LEPTOCOEISAEIA. 



Leptocorisaria, SfSJ, En. Hem. iii, pp. 84-5 (1873). 



This Division differs from the Jlicrehjt raria in having the second 

 joint of the rostrum not longer than the two apical joints together ; 

 the pronotum posteriorly is ahout one half broader than the head, 

 and the first joint of the rostrum extends beyond the eyes. 



The Leptocorisarhi are found in all the chief zoological regions; 

 China is the onlj^ recorded Palsearctic habitat ; their representation 

 in the Ethiopian Region is very limited ; and they are chiefly 

 jSTeotropical and Oriental insects. 



The Division at present contains about seven genera.
