2 S HOMOPTERA 



Characters. — This division, at present represented by four Eastern genera, is to be princi- 

 pally recognized by the following characters : -- The tegmina and wings are opaque and generally 

 more or less brilliantly coloured; the lateral margins of the pronotum are neither ampliated nor 

 dilated; the tympanal orifices are largely exposed, the tympanal coverings being a little narrower and 

 much shorter than the orifices, and with their anterior margins convex. 



The Gaanaria are found in British India, Burma, Indo-China, China & Sumatra. 



SYNOPSIS OF GENERA. 



A. Tegmina with the venation normal; apical anas eight. 



a. Greatest breadth of tegmina more than one third of their length. 



b. Head longer than pronotum, front somewhat pot redly produced . . . . i. Genus G.eana. 



b'. Head not longer than pronotum, front horizontally produced . . 2. Genus Taona. 



a'. Grealent breadth of tegmina only about one third of their length . . 3. Genus Bai.ivja. 



B. Tegmina with the venation reticulate, ulnar and apical areas broken up into 



many cellular divisions 4. Genus Talaini .a.

Characters. — Body long and moderately slender in the male, much shorter in the female; 

 head (including eyes) about equal in width to base of mesonotum, longer than pronotum, front somewhat 

 porrectly produced, ocelli about twice the distance from eyes as from each other; pronotum with the 

 lateral margins very slightly convex, the posterior lateral angles moderatelv lobately produced; abdo- 

 men in male long, moderately slender, in the female only about as long as space between apex of head 

 and base of cruciform elevation; tympanal coverings in male small, both narrower and much shorter 

 than the tympanal orificies; opercula in male small, transverse, not passing base of abdomen; anterior 

 femora strongly spined beneath; tegmina and wings opaque, the first with their outer margins somewhat 

 convexly rounded, their greatest breadth more than one third their length.
