on the meso- and metapleura and edges of the abdominal segments. 

 Legs brownish-testaceous, darker on the femora. 



Ventral sinus of the male genital segment deep, with a short 

 median tooth; its sides obliquely rounded; plates long, but little 

 separated at base; expanded apical plate as long as the slender base, 

 roundedly triangular, inner edges approximate, grooved, pygofers 

 just as long as the plates and concentric with them at their rounded 

 apex." 



Length of body, male 5 mm.; female 6 7.50 mm.; length to tip of 

 elytra, male 7 mm.; female 8 9.50 mm. 



The writer found this species very abundant at Muldon, 

 Miss., June 1, 1921, on the trunks of plum trees in an 

 orchard and also in sweepings made in pure stands of alfal- 

 fa; also very abundant at Prairie, Miss., June 11, 1921, and 

 at Gibson, Miss., June 27, 1921, on alfalfa. Six specimens 

 were taken at Agricultural College, Miss., Sept 7, 1909, three 

 on pecan and the others at light, by an unknown collector, 

 and five more were taken on pecan at same locality Aug. 30, 

 1915, by C. C. Greer. At the latter locality the writer found 

 this species abundant at trap lights from June to September. 



Two females and a male were sent to the writer by Mr. 

 F. M. Hull, collected at Harlingen, Texas, Aug. 4, 1921. 



The pecan, plum and alfalfa must be recorded as defi- 

 nite host plants and there are probably many others yet 

 to be noted.
