abundant. A slightly smaller, paler form is abundant on Mount 

 Banahao, Laguna, Luzon; this form has also been encountered 

 at Malinao, Tayabas, Luzon. 



Trobolophya philippinensis sp. nov. Fig. 5, a, b. 



Female. — Length, 5.5 millime- 

 ters. Pale green, head and legs 

 stramineous ; frontal and scutellar 

 carina? and outer margins of fore 

 tibise fuscous; spots on sides of 

 head showing through as small 

 spots on vertex at outer anterior 

 angles. Tegmina hyaline; longi- 

 no. s. Trobolophya pMuppinensis sp. tudinal veins dark f uscous, darker 



nov. ; a, vertex, pronotum, and scutellum ; 



b, head, pronotum, and scuteiium, side basally and on clavus, cross veins 

 view - and costa paler.

Luzon, Laguna Province, Mount Maquiling and Mount Ba- 

 nahao (coll. Baker), common. A smaller, paler form occurs in 

 the mountains of Benguet and Nueva Vizcaya. It is noteworthy 

 that in the case of T. montana, a larger, deeper green form oc- 

 curs in the northern mountains, and a smaller, paler form, on 

 Maquiling and Banahao; while in the present species just the 

 opposite is the case. This species is the one formerly referred 

 to T. jacobsoni by Melichar. 



Trobolophya benguetensis sp. nov. Fig. 6, a, b. 



Female. — Length, 7 millime- 

 ters. Body, including head, deep 

 green, sometimes with sanguin- 

 eous tinting between scutellar ca- 

 rinas; facial and scutellar carinas 

 concolorous ; outer margin of fore 

 tibise piceous. Lateral spots of 

 head showing through as narrow 

 black marks on vertex at antero- 

 lateral angles. Tegmina hyaline, 

 stigma stramineous ; veins, except 

 costa, all piceous-black, darker 

 basally. 

 Luzon, Benguet Province, Baguio: Nueva Vizcaya Province, 

 Imugan (coll. Baker). This species might be readily confused 

 with T. montana on superficial examination, as the two are of 

 similar size; but they can be readily distinguished *by the dif- 

 ferent form of head and by the markings.
