INSECUTOR INSCITI^ MENSTRUUS 07 



OPHTHALMOTHRIPS, new genus 



Head elongate ( in the genotype about twice as long as wide) 

 and somewhat prolonged in front of eyes ; vertex conically 

 produced and with the usual pair of prominent bristles near 

 anterior occellus ; eyes prominent, protruding, and on ventral 

 surface of head prolonged posteriorly much beyond posterior 

 dorsal margin (PI. II, fig. 1); lateral bristles minute; post- 

 ocular bristles normal ; antennae moderately long and slender. 

 Prothorax with both median line and anterior margin con- 

 spicuously thickened. Wings broad, without venation. Fore 

 tarsi armed. Abdomen normal. 



Type: Ophthalmothrips pomeroyi, new species. 



Allied to Blaphrothrips and Dicaiofhrips, but apparently dis- 

 tinct by the ventrally prolonged eyes and the thickened anterior 

 margin of the prothorax. 



Ophthalmothrips pomeroyi, new species. (PI. 11, figs. 

 1 and 4.) 



Female {macropteroits). — Length, about 2.9 mm. Color 

 black; antennal segments 1, 2, 7, and 8 dark blackish brown, 

 1 darkest, 2 yellow on outer apical surface ; 3-5 yellow, 3 

 clouded with brown in basal fourth, 4 and 5 clouded at apex, 

 the latter more darkly and broadly ; 6 brownish yellow, darker 

 apically ; fore tarsi yellow. 



Head widest across eyes and about 1.84 times as long as 

 greatest width, converging toward base ; vertex conically pro- 

 duced, overhanging base of antennae ; dorsal and lateral sur- 

 faces transversely striate and with a few minute bristles ; 

 postocular bristles pointed, equal in length to interval between 

 eyes. Eyes about 0.3 as long as head, rather strongly pro- 

 truding, prolonged on ventral surface of head much beyond 

 posterior dorsal margin (PI. IT, fig. 1). Ocelli almost ex- 

 actly equidistant, median ocellus situated at apex of produced 

 vertex and overhanging, posterior ocelli opposite a line drawn 

 behind anterior fourth of eyes. x\ntennae (PI. II, fig. 4) nearly 

 l.G times as long as head. Mouth cone short, semicircularly 

 rounded at apex.
