CHARACTERS OF SOME NEW SPECIES OF NORTH 

 AMERICAN HEMIPTEROUS INSECTS, WITH 

 ONE NEW GENUS 



EDWARD P. VAN DUZEE 



Curator, Department of Entomology 

 1. Brochymena hoppingi, new species 



Allied to affinis and with the same winged form of male 

 genital segment, but with shorter head and shorter second 

 antennal segment; nearly black with the pronotal margins 

 roundedly crenulate. Length, male 12; female, 14 mm. 



Male: Head slightly longer than broad across the eyes; cheeks overlapping 

 tylus, sometimes almost contiguous at apex; subapical angle obtuse or rounded; 

 second antennal segment two-thirds length of third. Sides of pronotum with 

 about five rounded teeth on anterior lobe, the humeral lobe rounded ante- 

 riorly as in affinis but scarcely crenulate, humeral angle less prominent; 

 surface deeply puntured and sculptured, the callosities more prominent than 

 in affinis. Scutellum a little shorter, scarcely raised at base, median line 

 subcarinate, surface more deeply pitted than in affinis. Elytra closely and 

 quite evenly punctured with a few smooth calloused points. Rostrum passing 

 middle of third ventral segment; venter nearly smooth with small, scattering 

 obsolete punctures, sulcus shallow but obvious. Genital segment greatly ex- 

 tended either side as in affinis, their apices distinctly surpassing line of 

 sixth abdominal segment, hind margin heavily bearded. 



Color, mostly black, the testaceous interspaces less conspicuous, lateral crenu- 

 lations of pronotum rufous; membrane with but few pale vermiculate marks; 

 femora with pale subapical mark and median annulus more or less distinct; 

 antennal incisures very narrowly rufous; connexivum with small marginal 

 spots and the incisures rufous, the median line of the venter narrowly rufous. 



Female: Larger with pale markings a little more conspicuous, especially 

 near apex of scutellum and on venter. 



Described from five male and five female examples taken 

 by Mr. Ralph Hopping from beneath bark of a dead conifer
