Professor C. F. Baker of the College of Agriculture, Los Banos, 

 P. I., recently sent me some specimens of a very interesting 

 psyllid which he had collected on leaves of Ficus ulmifolia Lam. 



This species of Psyllidse bears some resemblance to the mem- 

 bers of the genus Pauropsylla, which are more or less tropical 

 in distribution ; and most, if not all, of them produce malforma- 

 tions on the leaves of various trees — Ficus among others. 

 Several Psyllid larvae have been mentioned as making galls on 

 leaves of various species of Ficus in Java, and it is possible that 

 the specimens before me are the adults of one of these species. 

 However, none of these forms has been named, so that no confu- 

 sion will result from assigning a name to the Philippine species. 



A second collection of Psyllidse from the Philippine Islands, 

 sent by Professor Baker, contains some very interesting forms. 

 There is represented in the collection one new and very inter- 

 esting genus, as well as a new species of a genus described from 

 Formosa, an interesting new species of Pauropsylla, and one 

 new species of another genus, Euphalerus. The new species of 

 Pauropsylla is especially interesting because of the light it 

 throws upon the value of certain venational characters. 



Genus PATJROCEPHALA novum 



Body robust, surface shagreened; thorax strongly arched; 

 head very strongly deflexed, not quite as broad as thorax ; vertex 

 convex in front, coarsely shagreened; front globosely swollen 

 beneath antennal insertions, lobes or cones wanting; labrum 

 large. Eyes large, globose; ocelli large, prominent, posterior 

 pair elevated, anterior in front; antennse longer than width of 

 head; rostrum very long, prominent. Thorax broad; propleu- 

 rites similar to those of Pauropsylla; metascutum with a prom- 

 inent, erect, conical, tubercle dorsad. Wings hyaline, more or
