Hemelytra considerably surpassing apex of abdomen, clavus, mar- 
gins of embolium, corium and cuneus, and veins of membrane dark 
brownish ; inner apex of major areole rounded. 
FKemora with faint brown spots, third tarsal segment dark brown; 
length of posterior femora 2.2 mm., length of posterior tibiae 2.7 mm. 
Holotype.—U.S.N.M. No. 56716, female, Island of Penang, Straits of 
Malacca (Baker). 
MACRALONIDEA, new genus 
Body elongate, shining, clothed sparingly with very short hairs; 
pronotum very coarsely and deeply punctate, hemelytra hyaline. 
Head inclined, more or less rounded, seen from above wider than 
long, seen from side about as long as high; vertex very slightly con- 
vex, shortly longitudinally sulcate, immarginate, about as wide as an 
eye seen from above; frons slightly convex, clypeus moderately prom- 
inent, with apical two-thirds nearly perpendicular, jugum flat, buc- 
culae short, lower margain rounded. Eyes of medium size, moderately 
prominent, not touching anterior margin of pronotum, seen from side 
obliquely ovate, anterior margin moderately sinuate. Rostrum reach- 
ing base of intermediate coxae, first segment thick. Antennae linear, 
inserted near the middle of anterior margin of eyes, longer than body, 
first segment about as long as pronotum, second about twice as long as 
first and a little longer than third and fourth taken together. 
Pronotum coarsely and deeply punctate, a little wider than long, 
more than twice as wide at base as at apex, posterior lobe strongly 
convex, posterior margin straight before scutellum, humeral angles 
rounded and thickened, lateral margins vertically rounded, sinuate at 
apical third; apical collar not separated at middle, longer than thick- 
ness of first antennal segment, punctate at the disk of pronotum; calli 
small, smooth, slightly elevated. Mesoscutum covered, scutellum 
smooth, strongly elevated posteriorly before the narrow apex, punc- 
tate along the lateral margins. 
Hemelytra hyaline, horizontal, embolar margin slightly sinuate at 
middle, a series of punctures extending beyond the middle, corium and 
clavus without veins, a series of punctures along claval suture; cuneus 
longer than wide, membrane bicellulate. Xyphus concave, anterior 
part punctate, lateroposterior margins reflected. Propleura punctate. 
Ostiolar peritreme large. Legs moderately long, posterior femora 
thickened before apex, tibiae minutely and sparingly spinulose. 
Arolia large, divergent at apex. 
Related to hopalonsis Stal and Malalasta Distant but differing 
from both by different type of punctures on pronotum, longer prono- 
tum, different apical collar, and smooth and strongly elevated scutel- 
lum. | 
Genotype.—Macralonidea cyanescens, new species.
