Dictyophorodelphax praedicta sp. nov. 

 (Homoptera, Delphacidae) 



BY JOHN COLBURX BRIDWELL. 



Length 5.0-().4 iiiiii. ; length of prolongation of head in 

 front of eyes 2.5-2.8; length of teginen 1.3-1.6. 



Very mnch like D. mirabilis Swezey but darker. The pro- 

 longation of the head is shorter, only about the length of the 

 body and the apical depressed portion is much shorter and 

 compressed, the space between the dorsal carinae being acumi- 

 nate at apex. Lateral carinae confluent at about two-thirds of 

 their length from the base. 



The tegmina are shorter than in the other species, the four 

 apical segments of the abdomen being visible beyond them 

 instead of through, as in the case of the other two species. 

 The black dots along the veins are much reduced in compari- 

 son with the other species. 



The uym])hs closely resendde those of D. swezei/i Bridwell 

 but the prolongation of the head is slightly deflexed instead 

 of straight. 



S The genital styles are more elongate than those of D. 

 swezeyi and only gently curved, the slender })oints not being 

 clawlike as are those of D. mirabUis. The extreme apices are 

 slio-htlv blunt and recurved. 



Fig. I. Dictyophorodelphax praedicta, cdeagus (highly enlarged). 



The edeagus has the slender apical portion nearly in a 

 straight line with the not greatly stouter basal portion. The 

 ventral surface of the slender apical portion is covered with 

 many small reflexed teeth and there are two groups of stouter 



The figure is the work of Mr. W. R. R. Potter, illustrator for the 

 H. S. P. A. Experiment Station.
