Habitat. — The type emerged in November from a gall collected at 

 Camp Baldy, Calif., on November 7, 1939. One paratype was cut out 

 September 5, 1918, from a gall collected at Los Gatos. Another was 

 cut out November 10, 1949, from a gall collected at Idyllwild on No- 

 vember 6, 1948. One (not in the type series and all amber) was cut 

 out dead in 1946 from a gall collected on Mount St. Helena in August 

 1922. 



PARACRASPIS, new genus 



Genotype. — Gallirhytis guadaloupensis F^^llawa3^ 



Aga?nic female. — Head massive, broader than thorax, cheeks broad- 

 ened behind eyes, malar space without groove, antennae 14-segmented, 

 filiform, third longer than fourth, longer than first two. Thorax 

 normally arched ; pronotum narrowed to one-ninth in middle. Meso- 

 scutum broader than long, parapsidal grooves complete or incomplete, 

 median wanting. Scutellum rounded behind, with a transverse groove 

 at base, lateral impressions prominent. Mesonotum covered with uni- 

 formly distributed appressed hairs which almost hide the sculpture. 

 Mesopleuron pubescent. Tarsal claws with a tooth. Wings reduced 

 but with evident and nearly normal venation, reaching about to the 

 tip of abdomen. Abdomen longer than head plus thorax, second ter- 

 gite longest but not reaching half the length of the abdomen, remain- 

 ing five more or less subequal, sides of III- VI not pubescent. Ventral 

 spine broad, rounded at end, bristly as in Acraspis Mayr. Ovipositor 

 almost straight at end, rather short and stout. 



Differs from Acraspis Mayr in having less reduced wings, a more 

 robust thorax with a normally rounded scutellum. Genus erected to 

 include three agamic species, all from leaf galls not of the "hedgehog" 

 type on Qn^rcus chrysolepis in California. Sexual generation un- 

 known.
