3. Aradus Duzeei n. sp. 



Subovatus, fusco-niger, apice scutelli, limbis posticis segmentorum 

 connexivi, dimidio interiore loborum genitalium liturisque corii basin 

 versus flavidis, pedibus pallidis, antennis crassiusculis, margine laterali 

 pronoti et partis basalis corii dense sed subtilissime crenulatis. Long. $ 

 6 mm., 9 6^ mm. 



Male : hemelytra reaching the middle of the genital lobes. Genital 

 segment very convex, its apical lobes depressed and reflexed, the posterior 

 margin broadly rounded, the inner margins contiguous. Sixth segment 

 of the connexivum distinctly longer than broad, the apical part consider 

 ably narrower than the basal one. 



Female: hemelytra reaching the base of the genital lobes. Fifth ven 

 tral segment as long in the middle as at the sides, the posterior margin 

 truncate in the middle, the apical angles distinctly reaching beyond the 

 middle part of the sixth segment; sixth ventral segment in the middle 

 subequal in length to the fifth, its apical angles are almost opposite the 

 tip of the second genital segment; first genital segment shorter than the 

 sixth ventral segment in the middle, twice as long as the second genital 

 segment, the genital lobes a little reflexed, the posterior margin broadly 

 rounded, the inner margins contiguous. Sixth segment of the connexi 

 vum scarcely longer than broad, the apical part a little narrower than the 

 basal one. 



Dark brown. Head a little longer than broad, with two longitudinal 

 furrows; lateral spines valid, a little divergent, not reaching the apex of 

 the first antennal joint, without any distinct tooth on the outer side; in 

 traocular tubercle small, obtuse ; rostrum scarcely reaching the anterior 

 coxae; antennae rather thick, a little shorter than head and thorax taken 

 together, fuscous, basal joint pale testaceous, second joint as long as the 

 breadth between the eyes, very little shorter than the two last joints 

 united, cylindrical, a little narrower at base, considerably longer than the 

 third joint, which is also cylindrical, fourth joint much shorter than the 

 third. Pronotum broadest a little behind the middle, the sides moderately 

 reflexed anteriorly, sometimes with a paler spot, the lateral margins more 

 rounded posteriorly than anteriorly, densely but finely crenulated, the 

 base shortly and bluntly lobed above the base of the corium, the disk with 

 four parallel ridges, the inner ridges approximate, the outer ones 

 evanescent anteriorly ; besides these ridges there is the usual abbreviated 

 ridge at the basal angles of the pronotum. Scutellum elongate-triangu 

 lar, gradually and equally tapering from the base to the tip, twice as long 

 as broad, nearly reaching the posterior margin of the second abdominal 

 segment, rather broadly yellow at the apex. Hemelytra dark fuscous, the 

 transversal nervures and the somewhat dilated basal part of the corium, 

 except the exterior margin (which is densely and very finely crenulated), 

 are yellow. Abdomen fuscous, the posterior margins of the segments of 

 the connexivum and the inner half of the genital lobes tawny, posterior
