414 Treubia Vol. Ill, 3—4. 



slightly prominent, separated from the frons by an impression, genae rather low, gula 

 subhorizontal or somewhat oblique, antennae inserted immediately in front of the 

 middle of the eyes a little above the level of the base of the clypeus, much longer 

 than the body, slender and linear, but the first joint notably thicker with the apex 

 somewhat curvedly clavate, second joint much the longest, especially in the male, 

 rostrum scarcely reaching the middle coxae, the three first joints subequal in length, 

 basal joint thicker than the others, about reaching middle of eyes, fourth joint considerably 

 longer than third. Pronotum somewhat broader than long, rather strongly declivous, 

 the collar horizontal, as broad as the clavate apex of the first antennal joint, the 

 impressed line terminating it posteriorly rather feeble, calli transverse, not much elevated, 

 sides of pronotum immarginate, convex, broadly and slightly sinuate, a short longitudinal 

 impression within the narrowly rounded non-prominent humeral angles. Mesoscutum 

 almost entirely covered; scutellum slightly broader than long, laterally convex, obtuse 

 at apex. Elytra longly passing apex of abdomen, embolium linear, very narrow, the 

 narrow cuneus very much longer than broad, very acute at apex, the basal margin 

 oblique, the interior margin broadly sinuate, the cell of the membrane very long, reaching 

 much beyond apex of cuneus and centre of membrane, narrowly rounded at apex, the 

 vein forming its interior margin straight, originating near the inner basal angle of 

 the membrane and lying in the longitudinal axis of the elytron, the vein formig its 

 postero-exterior margin sinuate in the anterior half. Xyphus of prosternum somewhat 

 convex, but narrowly longitudinally impressed in the middle. Orificia small. All coxae 

 short, the intermediate pair rather widely separated, the hind pair still more so, placed 

 near the lateral margins of the metasternum; somewhat more than the apical half of 

 ail femora incrassated and curved, the incrassated part constricted a little apical of 

 its middle and at this place not thicker than the basal part of the femora, the space 

 between the stricture and the apex still thicker than the rest of the incrassated part; 

 all tibiae much longer than the femora, a little curved or angular at the base, then 

 gradually narrowed toward apex, but the apex itself again a little thicker; third tarsal 

 joint distinctly widened from base to apex, first joint of hind tarsi a little longer 

 than second. 



Differs from Eiicerocoris Westw. principally in the structure of the rostrum and legs. 



Arthriticus cugcniac n. sp. 



Glabrous, shining, sanguineous, head above black, front piceous, cuneus (except 

 base) fuscescent, membrane strongly infumated, vagina of female fuscous; antennae 

 fuscous, base of first joint pale yellow; legs black, coxae sanguineous, trochanters and 

 the non-incrassate basal part of femora pale red or yellowish, a pale yellow ring 

 occupying the stricture of the incrassated part of the femora, tibiae gradually becoming 

 lighter toward the apex which is rather broadly pale yellowish. Head about one-third 

 narrower than base of pronotum, first joint of antennae as long as head, pronotum and 

 scutellum taken together, second joint in the male about twice the length of first, in 

 the female somewhat shorter, third about one-fourth shorter than second, fourth shorter 

 than third, Pronotum at apex much narrower than head. Corium and clavus very finely 

 shagreened. Left genital clasper of male rather long, slender, curved. Vagina of female 

 not reaching middle of venter. Length, c^ 4 mm., incl. tegm. 5,8 mm.; $ 5 mm., incl. 

 tegm. 6,8 mm.

This Mirid bears a strong superficial resemblance to the small Indo- 

 malayan Reduviid Vesbius purpureas Thunb.
