Cryptin^. 

 Silsila striolata^ sp. n. 



Black, a broad band on the centre of the flagellum, face, 

 clypeus, mandibles, palpi, a narrow line on the upper inner 

 orbits, a line on the upper, a broader one on the lower edge 

 of prothorax, the line on the top, narrowed behind, scutcUums, 

 scutellar keels, a large, broad, triangular mark behind the 

 hind wings, the apical slope of metanotum, except in the 

 centre, the mark in the centre continued upwards to near the 

 transverse keel, this part becoming gradually narrowed, 

 from its outer edge at the apex a line of equal width runs 

 along the edge of the pleurae to near the spiracles and below 

 along the coxte, a broad curved mark on the lower edge of 

 the mcsopleura;, the base being narrower and continued 

 higher up than the apical, and lines of equal width on the 

 apices of the abdominal segments, pale yellow. Four front 

 legs pale fulvous, paler at the base; the fulvous tint on the 

 hind legs is deeper, the lower and outer side of their coxa?, 

 the apical joint of the trochanters, the apex of the femora 

 narrowly, and the base of the tibise still more narrowly, black. 

 Wings hyaline, the nervures and stigma black. ^ . 



Length 12 mm. 



Bidi, Borneo; July {ILnoitt). 



Face, except on the outer edges, closely, roughly punc- 

 tured, the clypeus smooth. Front stoutly, obliquely striated 

 below the ocelli, the lower part furrowed down the centre. 

 The yellow projectitig part of the pronotum stoutly striated ; 

 the upper pari of the i)vopleura3 irregularly, finely striated 

 and punctured ; the middle stuutly striated. Mesonotum 

 closely, distinctly punctured, finely striated on the edges of 

 the lubes; the scutel'.um smooth, its basal depression deep 

 with four stout keels ; the mesopleurse stoutly striated, 

 except in the middle at the apex. On the base of the 

 metanotum is a band of stout strise, closely pressed, but 

 clearly separated ; the space between them and the keel is, 

 in the middle, coarsely, closely shagreened, almost punctured; 

 the sides have the punctures clearly separated. Metapleune 

 closely, rugosely punctured, the punctures running into reti- 

 culations, especially at the base. The first abdominal segment 

 smooth and shining, the others opaque, aciculated.

Black ; a line on the inner orbits, a mark, longer than 

 wide, narrowed above, transverse at the apex, in the centre
