Hystiopsis peruensis, new species 



Figure 69 



About 6.5 mm. in length, elongate oblong oval, shining although 

 faintly alutaceous, the elytra distinctly costate with geminate striate 

 punctation in the intervals between; pale yellow with the head dark 

 brown to the pale mouthparts, elytra with a broad metallic blue vitta 

 running from the humerus down the side, a short sutural vitta below 

 the scutellum and a median elongate spot before the apex on each 

 elytron. 



Head with interocular space about half width of head, occiput 

 polished, with a few fine punctures, frontal tubercles somewhat swollen 

 and a shallow median depression above; lower front somewhat de- 

 pressed, a faint trace of median carina from between the antennal 

 sockets; head dark brown except for pale yeUow mouthparts. Anten- 

 nae brown with the three terminal joints paler. Prothorax somewhat 

 wider than long with nearly straight sides and a transverse depression ; 

 surface shining although faintly alutaceous and with scattered punc- 

 tures; entirely pale yellow. Scutellum pale. Elytra with seven or 

 eight pronounced costae and in the intervals between these shallow 

 and rather coarse geminate striate punctation, pale yellow with a 

 broad metallic blue vitta covering the humerus and extending down 

 the side to apical curve; another short sutural vitta running down a 

 little way below the scutellum, and an elongate median spot near the 

 apex. Body beneath and legs entirely pale. Length 6.5 mm.; width 

 3.5 mm. 



Type, female, Bowditch collection, MCZ 30681, from "Peru." 



Remarks: Bowditch has attached the manuscript name peruensis 

 to this species. Only one specimen is known, but it is clearly closely 

 related to H. marginalis (Fabricius) and others with the lower front 

 of the face somewhat depressed and without distinct carina and with 

 costate elytra. 



Hystiopsis terminalis, new species 



Figure 71 



About 6 mm. in length, elongate oblong oval, moderately shiny 

 although alutaceous, the elytra strongly costate with the intervals 

 geminate striate punctate, pale yellowish brown, the head with a dark 

 occiput, the elytra with dark piceous vittae along the side and suture 

 not reaching the middle, and a wide dark apical fascia, breast dark; 

 head depressed in front in the male. 



Head with the interocular space less than half width of head, eyes 

 prominent, occiput shining piceous, finely punctate, a median depres- 

 sion over the poorly marked frontal tubercles and the lower front 

 depressed with a ridge on either side below the antennal sockets,
