102 Mr. G. Meade-Waldo on 



abdominal segment at base. Punctured : clypeus, head, and 

 thorax coarsely cribosely, abdomen more finely. Whole 

 covered with grey pubescence of varying density, thickest on 

 clypeus and propleurae, but conspicuous on mesopleurse, disc 

 of mesonotum, and the abdomen both dorsally and ventrally. 



Length 9 mm. 



Hab. Kuching (Sarawak), 1899; 1 £ . 



Dedicated to Mr. J. C. Moulton, the Curator of the 

 Sarawak Museum. 



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

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

 pronotum being narrower than the width of the thorax at the 

 tegulae, whereas in 0. fulvipennis the anterior margin of the 

 prothorax is as wide as the thorax at the tegulse ; (b) by the 

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

 to the prothorax ; (c) by the absence of yellow behind the 

 eyes, on the prothorax anteriorly, and on the terminal 

 abdominal segments. 



Odynerus (Symmorphus) tukvarensis, sp. n. 



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

 margine antico utrinque maculato, 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 

 mesopleurse 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 turrow 

 divides scutellum from postscutellum, median segment with 

 a distinct dorsal surface, concavo-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 

 punctured ; median segment coarsely and cribosely punc- 

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

 minal segment very coarsely punctured . Wings f usco-hyaline, 

 rather more obscure towards costa.
