lucent, the veins pale ochraceous. Length, female, 7 millimeters ; 

 male, 6.5. 



Length of face (Plate 1, fig. 9, c) subequal to its width. 

 Face very similar to that of Signoretia malaya even in propor- 

 tions; facial keel extending to middle of clypeus, though not so 

 strong on clypeus as on front; the whole anterior portion of 

 clypeus strongly but not equally depressed; front very slightly 

 convex in profile (Plate 1, fig. 9, 6). Ocellar carina? and carina? 

 of vertex as in P. gratiosa. Ocellus a little farther from eye 

 than its own diameter. Length of vertex less than half width 

 between eyes, and subequal to anterolateral margin of pronotum. 

 Pronotum (Plate 1, fig. 9, a) a little more than three times 

 length of vertex; the anterolateral margin into width a little 

 more than three times ; thimble pitting entirely obsolete except 

 for faint indications along lateral borders; submedian carina? 

 similar to those of P. gratiosa, as is also the venation. 



Luzon, Benguet Province, Baguio {Baker). Not uncommon. 

 This very distinct species has the cephalic and thoracic 

 proportions of Signoretia malaya, but the pronotal carina? 

 and claval venation of Preta gratiosa. It differs from all 

 other members of the family in lacking the thimble pitting on 

 pronotum. 



EUACANTHID^E 



The accompanying figure (Plate 1, fig. 10) will make it clear 

 that in Euacanthus we are dealing with a type that not only 

 is closely related to Signoretia and Pythamus in several funda- 

 mental respects, but that also shows no affinity to the 

 Tettigoniellida? where it is usually placed. It is, in its way, as 

 isolated a type as either Ulopa or Paropia. The position of the 

 ocellus with the peculiar accompanying structures is similar 

 to that of the Signoretiidse and Pythamida?, as is the tegminal 

 venation. 



Bundera Distant 16 apparently belongs here, but the ocelli are 

 not mentioned in the generic description. 



PYTHAMIDiE 

 There can be no doubt of the interrelationship of Onukia and 

 Pythamus on the one hand, and Onukia with Tortor and Drya- 

 domorpha on the other. The structure of the pronotum, as in 

 the case of Muirella, suggests certain Jassaria, but the cephalic 

 characters are of greater importance and are unmistakable. Dis-
