appear to have the apical margin of the corium straight; that 

 this margin really is rather deeply sinuate interiorly is obvious, 

 if the insect be looked at obliquely from the side or from behind. 



Antillocoris helvipennis sp. nov. 



Oblong-oval, black, scutellum (excluding the transverse pos- 

 teriorly rounded basal area) and elytra testaceous with a more 

 or less distinct golden luster, especially on the membrane ; corium 

 and clavus punctured with fuscous; antennas, rostrum, and legs 

 testaceous, base of third and fourth antennal joints fuscous; 

 coxse and femora piceous. Head shining, impunctate above, 

 finely punctulate beneath, second joint of antennae one-half 

 longer than first, third subequal to first and a little shorter than 

 fourth, rostrum a little variable in length, reaching base of 

 venter or of third ventral segment. Pronotum finely and rather 

 sparsely punctate, with a transverse, percurrent, antemedian, 

 impunctate area, lateral margins slightly sinuate, basal margin 

 straight. Scutellum moderately thickly and somewhat coarsely 

 punctate, the black basal area more finely punctate and emitting 

 an impunctate median keel to the apex. Corium, apart from 

 the usual seriate punctation along the veins, punctulate only in 

 the outer apical area of the mesocorium. Underside of body 

 mostly impunctate, but pectus with a row of coarse punctures 

 in the transverse impression of the propleura and metapleura. 

 First joint of hind tarsi not quite twice the length of the others 

 together. 



Length, male, 2.8 millimeters; female, 3.3.

Mizaldus montiscandens sp, nov. 



Black, elytra translucent, whitish, apical angle of corium black ; 

 antennae fuscous, apical half of first and extreme apex of second 

 joint whitish (fourth joint wanting) ; rostrum testaceous, basal 

 joint fuscous; legs stramineous, coxae, trochanters, and extreme 

 base of femora piceous, apical third of hind femora slightly 

 tinted with brownish. Head, pronotum, and scutellum very 

 thickly and finely punctured, antennae about half the length of 

 the body, posterior pronotal lobe distinctly shorter than anterior 

 lobe, its basal margin in front of elytra depressed and very 

 slightly lobately produced. Elytra reaching apex of abdomen, 

 the claval rows of punctures and the two adjacent corial rows 

 very palely bro\\'nish, the rest of corium impunctate, only the 

 exterior half with an oblong median area very finely punctured 

 with blackish.
