NEOBROTICA AND RELATED GENERA — BLAKE 337 



spot on the humerus, the apex dark with 2 round pale spots in the 

 middle, tibiae and tarsi dark. 



Head with the interocular space half width of head, occiput shiny, 

 finely punctate, a depression over the frontal tubercles, lower front 

 depressed, without carina, piceous, except about the jaws. Antennae 

 pale with the intermediate joints deeper brown. Terminal joints 

 missing. Prothorax with a transverse sulcus, alutaceous, finely punc- 

 tate, pale 3^ellow. Scutellum pale. Elytra shrunken as specimen is 

 inmiature, but still with signs of costae discernible, and the punctures 

 in the intervals geminate striate, pale yellomsh brown with a small 

 spot on the humerus and at the apex a dark band with 2 median 

 round pale spots. Body beneath pale with the breast dark; tibiae 

 and tarsi more or less dark. Length 7.4 mm.; width 3.5 mm. 



Type, female, BMNH, from Cuenca, Ecuador. 



Remarks : The ely tral color pattern of this species is unUke that of 

 any other examined. 



Hystiopsis grossa, new species 



Figure 84 



Between 8 and 10 mm. in length, oblong oval, shining, although 

 faintly alutaceous, the elytra with 7 or 8 feeble costae and with rather 

 coarse geminate striate punctures in the intervals; pale yellow brown 

 with a piceous head and dark intermediate joints of the antennae, 

 the elytra dark with metallic green or purphsh lustre, the margin, 

 apex and four spots pale yellow brown, in one specimen the apical 

 two spots coalesce at the suture; breast, tibiae and tarsi dark. 



Head with the interocular space approximately half the width of 

 the head, a median depression above the rather swollen but in- 

 distinctly marked frontal tubercles, occiput alutaceous and finely 

 punctate, the lower front smooth, shining black, with very little 

 evidence of a carina in the female (no males examined), and in some 

 specimens the lower front somewhat concave; antennae long, the 

 three basal and three terminal joints pale. Prothorax broad but not 

 twice as wide as long with shghtly curved sides and a rather shallow 

 transverse depression; surface shining although alutaceous, finely 

 punctate, entirely pale. Scutellum pale. Each elytron with 7 or 

 8 distinct costae, the intervals tending to be geminate-striate 

 punctate; surface alutaceous but somewhat shiny metallic green with 

 four large pale yellow spots, two on each elytron, the ones below the 

 middle in one specunen coalescing at the suture, apex widely pale and 

 the margin pale. Body beneath pale with the breast dark, femora 

 pale, tibiae and tarsi brownish, all tibiae with spines, anterior coxal 

 cavities open, claws appendiculate. Length 7.5-9.8 mm., width 

 4-5 mm.
