d" 2.1 and 2, 9 2.2 and 2.3; length of pronotal lateral lobe <? 2.2 

 and 2.1, 9 2.2 and 2.1; depth of pronotal lateral lobe d* 1.7 and 



1.7, 9 1.8 and 1.8; length of tegmen cT 17.4 and 17, 9 18 and 18.7; 

 width of tegmen d 1 2 and 2, 9 2.1 and 2.2; length of cephalic femur 



cT 4.3 and 4.3, 9 4.2 and 4.2; length of caudal femur J 1 10 and 10,

In additional to the described pair, a paratypic male, bearing 

 the same data as the type, and a paratypic female bearing the same 

 data as the allotype, are before us. 



Xiphidiopsis cryptosticta new species. Plate XIX, figure 13. 



This species has the tegmina marked faintly with suffused spots 

 of brown, the genicular lobes of the cephalic and caudal femora 

 suffused distad with brown, the latter unispinose. 



In the female sex, which alone is known, the subgenital plate is 

 broad, the disto-lateral portions with margin broadly convex and 

 the median portion with distal margin concave. This is a very 

 different type from that developed in X. lita Hebard and X. dicera 

 described above. It is a much more simple development of the 

 type found in the very distinct X. drepanophora described below. 



Type: 9 ; Singapore, British Straits Settlements. (From C. F. 



Baker.) [Hebard Collection, Type no. 826.] 



Compared with the female sex of dicera, the present insect is 

 found to show the following diagnostic characters. Size medium, 

 form slender. Vertex showing a weak sulcation, which in basal 

 portion broadens into a shallow depression. Last joint of maxil- 

 lary palpus equal in length to fourth. Pronotum with metazonal 

 portion about two-thirds as long as prozonal portion; lateral lobes 

 with margin curving evenly to ventral angle, which is more strongly 

 rounded, concavities of caudal margin opposite humeral sinus and 

 thoracic foramen very weak and of equal degree. Supra-anal plate 

 small, shield-shaped, with apex rounded and dorsal surface weakly 

 concave. Cerci of same type as in dicera but more elongate, nearly 

 four times as long as greatest width, with apical portion very slender. 

 Ovipositor as in dicera, except that the distal extremity of the 

 ventral valves is even more weakly specialized. Subgenital plate 

 distinctive; not narrowing to the distal extremity, latero-distad 

 with margins broadly convex, mesad with distal margin concave; 

 surface transversely shallowly concave meso-proximad and shal- 

 lowly concave in disto-lateral portions. Limbs more elongate 

 than in dicera. Genicular lobes of cephalic and median femora 

 bluntly rounded, of caudal femora unispinose. Cephalic tibiae 

 armed with the same number of spines as in dicera, these, however, 

 much shorter, the longest slightly over twice (in one paratype 

 varying to slightly over three times) the tibial width at that 

 point. Median tibiae as in dicera, except that the internal of the 

 proximal pair of spines is often missing.
