Vol. VIII] VAN DUZEE—NEW SPECIES HEMIPTERA 307 



fuscated, those of the front black at base and infuscated at apex next the 

 clypeus. Cheeks, pleural pieces and basal angles of the mesonotum marked 

 with black ; median compartments of the mesonotum clouded with black 

 at base and again beyond the middle. Elytra cinereous becommg whitish 

 at apex with pale fulvous nervures, dotted and maculated with fuscous, 

 the larger spots omitting the clavus and forming about three transverse 

 vittse on the corium; costal area with an elongated blackish spot near the 

 base a small one at apex and two well defined spots between; the apical 

 two 'thirds of the stigma black; membranal portion mostly immaculate. 

 Abdomen more or less clouded with fuscous on its disk ; legs pale. Basal 

 segment of the antennae pale yellowish. Ocelli fulvous. 



Described from 35 specimens, representing both sexes, taken 

 on the dead reflexed leaves of the California fan palm, Wash- 

 ingtonia filifera, in Andreas' Canyon at Palm Springs, Calif., 

 May 9, 1917. I have dedicated this interesting species to my 

 wife, Helen Van Duzee, in recognition of her enthusiastic inter- 

 est in entomological pursuits. This is our largest Catonia and 

 quite distinct from any other known to me. It seems to be 

 confined to this palm and to find its sustenance among the dead 

 foliage only, as I was unable to obtain any from the living 

 leaves.

39. Catonia necopina, new species 



Allied to nervata and albocostata; dark fuscous-brown with 

 the vertex and pronotum paler ; costal and apical veins of the 

 elytra whitish; length 5-53^ mm. 



Vertex short, rounding over to the base of the front, the lateral carinae 

 forming a subacute angle before ; base angularly emarginate. Front a little 

 convex in both diameters, very slightly widened toward the clypeus with 

 the sides feebly arcuated; sides acute but scarcely elevated; median carina 

 obsolete; barely indicated at the clypeal suture; surface closely uniformly 

 punctured as is also the clypeus, the latter with an indistinct median carina. 

 Pronotum as in the allied forms. Mesonotum closely evenly punctured, 

 the carina obtuse, nearly parallel. Elytra deep smoky subhyaline without 

 reticulations or dots, the nervures distinct. Costal margin with but three 

 areoles between the stigmatal and transverse veins. Lateral plates of the 

 female genital segment transverse-quadrangular, their inner angles sub- 

 acute; plates of the male about twice longer than wide, parallel, their 

 apices obliquely cut off; median tooth half the length of the plates, 

 rounded at apex. 



Color deep smoky brown becoming a paler fulvous-brown on the head 

 and pronotum; the patagise and costal margin whitish. Elytral nervures 

 paler beyond the middle, more conspicuously whitish at apex. Front deep 

 fuscous-brown shading to paler at base. Mesonotum tinged with cas-
