elongate marginal spot before middle, and a marginal spot to 

 membrane pale ochraceous ; between these spots the margin 

 is much darker ochraceous ; second and third joints of an- 

 tennae subequal in length, each a little longer than first, 

 fourth longest, incrassate and pilose; pronotum strongly 

 transversely impressed, punctate and wrinkled at anterior 

 margin, the posterior area discally foveately depressed, ante- 

 riorly coarsely punctate, posteriorly finely transversely 

 striate; scutellum distinctly centrally longitudinally carinate; 

 membrane not quite reaching the apical abdominal segment ; 

 posterior femora finely spined beneath, the posterior tibiai 

 strongly marginally setose ; basal joint of posterior tarsi 

 much longer than the second and third joints.

 beneath, and femora black; first and second jomts of an- 

 tennce (excluding extreme apices of second joint), tibiae, and 

 tarsi pale ochraceous ; hemelytra milky white ; internal vein 

 and margins of clavus, two principal veins of corium on 

 apical half, the oblique margin separating corium from 

 membrane, two internal curved veins and a large discal spot 

 to membrane, piceous ; second and fourth joints of antennte 

 subequal in length, each a little longer than third ; pronotum 

 ■with the anterior area or lobe smooth and centrally longi- 

 tudinally grooved or sulcate, the posterior area or lobe 

 coarsely punctate and depressed, with a distinct transverse 

 ridge before basal margin, the lateral margins concave;

This species is allied to both M. spinamanus, Motsch., and 

 21. punctatus, Walk., by the sulcated anterior pronotal lobe : 

 from M. spinamanus it is to be separated by the longer hem- 

 elytra and the colour of the legs ; from M. punctatus it differs 

 in the smaller size, the ochraceous first and second antennal 

 joints, more distinct sulcation to pronotum, ochraceous 

 tibiae, &c. 



Macropes singxdaris, sp. n. 

 Head, pronotum, scutellum, body beneath, and legs black;
