median emargination on either side of which the margin goes laterad 

 at a right angle to a sinus just before the rounded anterolateral 

 termination; front with a median sulcus extending half the distance 

 to anterior ocellus and with moderately large punctures confluent 

 to subconfluent in vertical rows from antennal insertions two-thirds 

 of distance to anterior ocellus; remainder of front with smaller, 

 scattered, shallow punctures; vertex more sparsely punctate than 

 upper front; ocellocular distance 2.5-3.0 times the postocellar distance 

 and 0.53 times the ocelloccipital distance; anterior ocellus slightly 

 closer to occiput than to apices of antennal tubercles; head beneath 

 rounded posterolaterally. 



Pronotum with anterior margin not ridged, the disk with shallow, 

 scattered punctures, separated by two or more times the diameter 

 of a puncture; laterally the punctures somewhat closer except in 

 lower posterior area, where they are confluent; scutum with somewhat 

 larger and closer punctures, some of which are confluent in rows 

 posteriorly in the middle; scutellum slightly longer than scutum, 

 the punctures slightly larger and more scattered, and with a shallow, 

 narrow median sulcus on anterior third; postscutellum with smaller 

 contiguous punctures in middle; mesopleural disk slightly produced 

 anteriorly beyond the concave anterior part of the sclerite, the discal 

 punctures quite scattered except posteriorly along upper margin; 

 metapleuron with minute, close punctures; propodeum dorsally with 

 a shallow, median depressed area tapering gradually toward the 

 posterior margin, laterad of this with scattered shallow punctures; 

 posterior surface of propodeum rather densely punctate; lateral sur- 

 face of propodeum with oblique rugae; hind tibia at apex on internal 

 surface without flattened setae; inferior margin of hind femur right 

 angled at middle. 



Disk of first tergum not ridged anteriorly, with scattered small 

 punctures as on succeeding terga; last tergum polished and with 

 somewhat closer punctures except apical fourth impunctate.

Hylomesa bakeri, new species 



Figure 3 



The small size and sparser punctation of both sexes readily distin- 

 guish bakeri from other species in the genus. In addition, the female 

 differs from most other Hylomesa in the entirely polished pygidium, 

 more sharply angled inferior margin of hind femur, and the simpler 

 mesopleural disk, which is not extended anteriorly beyond the ante- 

 rior surface of the mesopleuron. The male has the sterna with very
