Deraeocoris ( Heteroptera, AIiridae) 99 



Deraeocoris (Camptcbrochis) ornatus new species 



Very similar to citiicatiis. but segment II of the antennae is shorter in 

 proportion to length of pronotum, also the punctures on the disk are finer ; two 

 rounded fuscous spots on apical half of membrane are suggestive of ncbtilosus 

 but darkest specimens may develop a brownish cloud distad of the spots. 



S. Length 4.5 mm. Head: width 1.01 mm., vertex .4 mm., length .48 

 mm. ; nearly as in citucafits. the front less convex, reddish brown each side of 

 median line ; lorae, genae, bucculae, apical margin of tylus, and two impressed 

 spots on vertex, black. Rostrum, length 1.48 mm., nearly as in cuiicatus. 



Antennae: segment I, length .34 mm., basal half reddish brown, piceous 

 apically; II, 1.11 mm., scarcely equal to length of pronotum, thickness .085 mm., 

 black, brown annulus indicated, at middle; III, .4 mm.; IV, .4 mm.; last "lwo 

 segments black, pale pubescent as in ciiiicatiis. 



Pronotum : length 1.14 mm., width at base 1.92 mm., anterior angles .92 

 mm., collar .67 mm. ; more finely punctate and the lateral margins of the disk 

 more nearly straight than iii ^uneatus; calli black, reddish brown around the 

 margin and extending more or less toward the anterior angles of disk ; grayish 

 testaceous, paler near margins of disk and at the median line, not so distinctly 

 brownish as in cuncatns. .^cutclluin reddish brown or becoming piceous, punc- 

 tures black, apex and lateral margins ivory-white, median line usually indicated ; 

 mesoscutum black, scarcely exposed. Sternum and pleura black, posterior and 

 ventral margins of epimera brownish ; ostiolar peritreme white. 



Hcmclytra : width 2.08 mm. ; grayish translucent, punctures, f renal margin, 

 more or less along commissure, spot at middle and along apical margin of cer- 

 ium, piceous, tip of embolium reddish translucent. Cune^is red, translucent, 

 paler at inner angle and outer margin, slenderly piceous on inner margin near 

 apex, several very fit;e black punctures evident. Membrane pale, brachium in- 

 fuscated, more or less invading the membrane on both sides ; a pair of rounded 

 fuscous spots on the apical half, one each side of the middle, darkest speci- 

 mens developing a brownish cloud distad of the spots. 



Legs: coxae black, the apices and trochanters testaceous; femora reddish 

 brown, piceous on the basal half, in darkest specimens only the apical one-third 

 paler and annulated with reddish ; tibiae nearly as in eujieatus, annulations dark 

 reddish or piceous ; tarsi brownish black, the two basal segments paler. 



Venter: dark reddish to piceous and black, shining, pale yellowish pubescent; 

 genital claspers (PI. X) distinctive of the species. 



?. Length 4.8 mm., width 2.34 mm„, very similar to the male; segment 11, 

 length 1.08 mm., slightly shorter than length of pronotum (1.2 mm.), black, 

 the middle one-third testaceous or brownish, all the other segments black, 

 pubescence as in cuneatus.
