tliorax are a ])n)ail Jatorally pxpaiidp.l hum} on the prothorax, the 

 tii})ercles, a.ii L-shaperl mark l.elow. te^rulae, dotis on basal angles of 

 mesonotuni, soutelknn and postsrutelluni, and veiy large oval spots on 

 either side of nietanotnni. 



Abdomen petioliform, very -n-^akly and sparsely punPturod on a 

 shagreened ba-kgroiind. The segments are all yellow except the extreme 

 ba,ses, broader on first and second, narrow on the remainder, the last 

 segment ferruginons. 



Legs reddish yellow, with coxa.e and trochanters largely, and femora 

 towanls base, piceoiis. Anterior femora gradually broadened below in 

 to a broad flattened inflation. 



Wings, evenly fuscous, the veins towards base and the stigma pale 

 straw colored, the remainder darker. Second cubital cell much shorter 

 than third on the cubita.l nervure. Third abscissa of the radius twice 

 the length of the first two together.

5793 . . Hoplisoides umbonatus n. sp. 



A rather small black species with yellow markings, the legs yellow 

 and black and the wings dark fuscous on costal half. 



Male: Length 8 mm. Pubescence very fine and appressed, incon- 

 spicuous excepting on la.st two abdominal segments, where it is longer 

 a.nd slightly golden. 



Head large and thick, slightly broader than the tliorax, subqnadrare 

 a.s viewed from above. Head very sparsely punctured on a background 

 of exceeding fine and dense puncturation, sides of face and supraelyp- 

 6al area nearly smooth. Inner orbits not at all emarginate above, and 

 Hcarly parallel below. Face below antennae, inner orbits, and scape 

 underneath, bright yellow. Flagellum piceous above, ferruginous below, 

 the eighth article In-oadly excavated underneath. 



Thorax very sparsely punctate an a smooth or somewhat shagreened 

 background: scutel minutely punctured. Mesopleurae bounded in front 

 amd below by a non-foveolated furrow, the broad and shallow furrow 

 between meso and metapleurae broader below, carinately rimmed, its 

 anterior face rugose. Upper area of metanotum with seven or eight 

 deep sn'ooth closely ap])roxin'ated oblique grooves on either side of 

 the miedian groove, the bounding foveolaited groove rapidly broadening 

 caudad to the rather small median fovea. The posterior face of meta- 

 notum is in large part covered with deep very coarse longitudinal 

 rugae. The yellow markings on thorax are a broad line on pronotum. 

 the tubercles, an irrregular elongate patch below tegulae, narrow line 

 on sides of metanotum. Tegulae ferruginous with a yellow dot. Abdomen 

 not at all petiolate. black, with apical yellow bands, very broad and 

 deeply emarginated on 1 and IT, narrower on the others. The band is
