deep, humeral sinus subobsolete. Tegmina foliaceous, rounding 

 broadly distad at apex, veins and veinlets strongly denned in color, 

 stridulating area large, with a large oval veinless area caudad. 

 Wings small, parachute like, showing distinct reduction and in- 

 capable of sustained flight. Prosternum strongly bispinose. Meso- 

 sternum with cephalic margin raised and tuberculate, this and the 

 metasternum produced caudad in rounded -triangular lobes. Ce- 

 phalic and median coxae bluntly angled proximad, the former with 

 a heavy externo-lafceral spine. Limbs slender. Femora unarmed, 

 the genicular lobes angulate-rotundate; cephalic femora carinate 

 dorsad, much longer than the median femora. Cephalic tibiae 

 flattened dorsad between the very slightly raised lateral margins, 

 this surface entirely unarmed; auditory foramina apert on both 

 sides. 



Chloracantha lampra new species. Plate XIV, figures 15 and 16; plate XV, figure 2. 



This species is widely distinguished from those of the genera, 

 nearest to which it is placed, by its small size and great differences 

 in the pronotal, tegminal and limb development. 



The heavily spined lateral margins of the pronotum and green 

 coloration, with beautifully but delicately marked tegmina, give 

 this little insect a very distinctive appearance. 



Type: cf 1 ; Townsville, Queensland, Australia. [Hebard Col- 

 lection, Type no. 807.] 



In addition to the characters given in the generic description, 

 the following are noted. Size small, form moderately slender. 

 Maxillary palpi moderately elongate, fourth joint slightly shorter 

 than third, third three-quarters as long as the fifth, the latter ex- 

 panding distad at the obliquely truncate apex. Lateral margins 

 of pronotal disk with large, rather slender, blunt spines, directed 

 laterad and weakly dorsad, two on the prozona, two on the meso- 

 zona and three on the metazona on each side, the first and last 

 much smaller than the others; lateral lobes with ventral margin 

 nearly straight and weakly oblique, this margin and the rounded 

 ventral angles supplied with irregular tubercles, three such tubercles 

 being also present on the face of the lateral lobe. Tegminal vena- 

 tion forming a large and rather irregular series of angular areas; 

 apex of tegmen at costal margin, broadly rounded. Supra-anal 

 plate produced in a hooded lobe, with sides curling inward so that 

 only a narrow vertical slit is seen meso-caudad and completely 

 concealing the cerci. Subgenital plate small, narrowing to the 

 narrowly V-emarginate apex. Cephalic tibiae narrow very gradu- 

 ally beyond the auditory foramina. 



General coloration light elm green. Eyes warm sepia. An- 

 tennae verona brown. Tegmina with veins outlined in elm green, 

 the areolae between light elm green in central portions, margined 

 with greenish buff about the periphery of each, with a number of 

 irregularly placed, round spots of apricot yellow; toward the costal
