Type, H. coccineUoides, Barm., from the Philippines. 



Distribution. Oriental and Malayan Regions. 



Apical joint of rostrum longer than thick, oval, oblong, or 

 elongate ; tegmina entirely convex, distinctly or obsoletely veined, 

 sometimes the venation is apparently absent ; clavus and corium 

 counate, no claval suture ; body depressed ; vertex narrower than 

 eyes or subequal in breadth ; pronotum truncate at base, sinuate 

 behind the eyes, the sides behind the eyes hardly visible from 

 above ; posterior tibiae bispiuose ; anterior femora simple. 



These insects have a strong superficial resemblance to the 

 Coccinellidae, or " lady-bird " beetles. It is probably owing to 

 the well-known variation existing in some of the species of those 

 Coleoptera, that a similar amount of variability has been suspected 

 in these Homoptera. I do not think this exists in anything like 

 the extent predicated by some writers, and in most eases, where I 

 have been able to examine a fair series of specimens, a usual 

 amount of specific constaucy is observable.
