ZOOLOGICAL LlTEllATURE. 
Halyomorpha, g. n., Mayr, 1. c. p. 911. Allied to Pentatoma] head* broad 
and rounded at apex, lateral margins elevated; second joint of antennae 
shorter than third, remainder nearly equal ; bucculae narrow, dilated in front ; 
rostrum reaching second or third segment of abdomen, second joint scarcely 
twice as long as first ; ocelli distant ; pronotum with a tooth at anterior angles, 
lateral angles prominent ; membrane \vith nine nearly parallel veins ; meso- 
sternum caiinated. Type Ilalys timorensis (Hope). 
Mhombocoris, g. n., Mayr, 1. c. p. 912. Allied to Pentatoma \ antenufe stout, 
basal joint very short, second long, fourth narrowly petiolate at base; rostrum 
reaching base of thorax, basal joint as long as head, second twice as long, 
third and fourth short ; mesosternum carinate ; abdomen unarmed. Sp. P. 
syriacus, sp. n., Mayr, 1. c. p. 912, from Syria. 
Cylmdrocnemaj g. n., Mayr, 1. c. p. 912. Allied to Ditomotarsus (most 
nearly to Planois, Sign.) ; abdomen rotundato-carinate, with a rounded pro- 
tuberance at the base ; third joint of antennae as long as the first. Sp. C. 
plana, sp. n., Mayr, 1. c. p. 913, from Chili. 
Acledra, g. n., Signoret, Ann. Soc. Ent. Fr. 4e s^r, tome iii. p. 647. Allied 
to Pentatoma ; lateral lobes of head longer than median, elevated at the sides ; 
humeral angles prominent, sides of thorax margined ; membrane with nine or 
ten veins; fifth joint of antennae longest. Sp. A. rejlexa, sp. n.. Sign. 1. c. 
p. 647, pi. 12. fig. 13, from Chili. 
Signoret (/. c. p. 548) proposes the formation of a subordinate 
group, to which he gives the name of Bitomotar sites, for a set of 
Pentatomid insects in which the sternum is unarmed, the tibiae 
cylindrical, and the tarsi composed of only two joints. The type 
of this group is the genus Ditomotarsus of Spinola; Signoret 
establishes the following genera belonging to it : — 
I. Abdomen unarmed. 
a. Humeral angles rounded Ditomotarsus 
b. Humeral angles spinous. 
* First joint of antennae shorter than head . . . .Nopalis, g. n. 
t First joint of antennae longer than head . . . .Planois, g. n. 
II. Abdomen spinous. 
a. Elytra with more or less regular longitudinal veins. 
Sinopla, g. n. 
b. Elytra with more or less irregularly anastomosed veins. 
* Humeral angles rounded Sniploa, g. n. 
t Humeral angles angular Lanopis, g. n.
