Most nearly allied to 0. fulvipennis, Sm., from Celebes, 

 but can be distinguished («) by the anterior margin of the 

 pronotum being narrower than the width of the thorax at the 

 tegulie, whereas in O . fulvipennis the anterior margin of the 

 prothorax is as wide as the thorax at the tegulae ; (6) by the 

 narrower head, as the head in each species is equal in width 

 to the prothorax ; (f) by the absence of yellow^ behind the 

 eyes, on the prothorax anteriorly, and on the terminal 

 abdominal segments. 



Odynerus {Symmorphus) tukvarensis, sp. n. 



Iv'iger, sparse punctatus; pronoti angulis anticis acutis; pronoti 

 margine antico utrinque raaculato, scutello bimaculato ; abdominis 

 segmentorum 1, 2 margine postico, tibiis tarsisque luteis ; alis 

 fusco-hyalinis. 



$ . Black ; an oval spot on clypeus, two minute oval spots 

 above the insertion of the antennse, a minute spot behind 

 each eye, the anterior angles of the pronotum, a spot on 

 nicsopleurse on each, two elongate marks on posterior margin 

 of the scutellum, apical margin of first abdominal segment 

 dorsally, apex of second abdominal segment both dorsally 

 and ventrally, yellow. Scape beneath, the tegulse, tibiae, and 

 tarsi ferrugineous. Clypeus ovate, rather broadly truncate 

 at the apex, pronotum produced to form a sharp angle on 

 each side of anterior margin, a deep transverse hirrow 

 divides scutellum from postscutellum, median segment with 

 a distinct dorsal surface, coucavo-truncate posteriorly ; first 

 abdominal segment as in typical Symmorphus, about as wide 

 as median segment, second abdominal segment separated 

 from first by a constriction. Punctured : clypeus shining, 

 minutely, head and pronotum rather more coarsely, meso- 

 notum traversed by two longitudinal furrows, sparsely 

 ])unctured ; median segment coarsely and cribosely punc- 

 tured, first abdominal segment finely, base of second abdo- 

 minal segment very coarsely punctured. Wings fusco-hyalinc, 

 rather more obscure towards costa.
