Vol. VIII] VAN DU ZEE— NEW SPECIES HEMIPTERA 291 



ated; anterior narrowly depressed imitating an obscure collum. Elytra 

 parallel on basal half, much expanded posteriorly, the polished apical por- 

 tion of the corium strongly marked and covering only the costal half beyond 

 the second transverse line of silvery hairs ; this line moderately oblique 

 and not at all dislocated on the clavus as in walshi. Antennae slender ; first 

 segment about as long as the eye ; second nearly as long as the head and 

 pronotum united, not obviously thicker at apex; third about one third the 

 length of second. 



Color reddish or brownish fulvous, becoming pale on the elytra ; disk 

 of the vertex and pronotum shading darker; extreme apex of the clavus 

 and polished area at apex of the corium fuscous. Scutellum and elytra 

 with the usual lines of deciduous silvery hairs ; the basal line on the 

 corium short, the apical retreating somewhat at the costa and continuous on 

 the clavus. Cuneus fuscous with an oblique line of silvery hairs from near 

 the inner angle well toward the costa along the basal suture. Membrane 

 dark with a large smoky cloud. Beneath bright fulvous with the abdomen 

 piceous. Legs fulvous, the hind pair infuscated. Antennae reddish brown, 

 pale at base; (fourth segment wanting}. 



Described from two female examples; one taken at Colton, 

 Calif., May 28, 1917, the other from Alpine, San Diego County, 

 taken October 3, 1913. This is a small, clearly marked species 

 which may be distinguished by the slender antennse, long head, 

 short basal segment of the antennae and bicolored apex of the 

 corium.

21. Pilophorus tomentosus, new species 



Form of davatus; dull cinnamon brown, rather densely 

 clothed with soft pale hairs ; posterior silvery line not dislo- 

 cated on the clavus. Length 4^^ mm. 



Head long, produced below the eye considerably more than the length 

 of the eye ; base of the vertex but feebly depressed, the hind edge sharp 

 but scarcely carinated. First antennal segment barely attaining the apex 

 of the head ; second as long as the head, pronotum and scutellum together, 

 moderately thickened at apex ; third and fourth together three fourths 

 the length of second ; fourth one half longer than third. Pronotum parallel 

 on anterior two thirds, then abruptly flaring to the humeri. Rostrum reach- 

 ing the tip of the hind coxae; first segment just surpassing the bucculae. 

 Elytra a little narrower than in davatus; moderately expanded at apex; 

 posterior line of silvery hairs a little oblique but not dislocated at the clavus. 

 Apical field of corium obscurely polished on costal half onlj^ 



Color a dull cinnamon brown, sometimes a little clearer on base of the 

 elytra and beneath, more or less tinged with red on the head, pronotum 

 and antennae. Apical portion of second and third antennal segments 

 fuscous, the fourth whitish, infuscated at apex. Scutellum with the usual 

 lateral and apical lines of silvery hairs. Posterior silvery line of the elytra 

 a little advanced at the commissure, not dislocated at claval suture. Pol-
