ed by a deep five-sided fovea. The deep median furrow of the upper 

 area ia continuous with that on posterior area where it is foveolate. 

 The vellow miarkings on thorax are a narrow band on pronotutn, 

 tubercles, quadra^ngular patch below tegulae, small dashes near hiu'l 

 angles of mesonotum and postseutel. The tegulae are piceous within 

 to ferruginous without. 



Abdomen not petiolate, black, dorsal siegments T to IIT with narrow 

 subapical bands which are broadened laterally. On doa-sum the punctu- 

 ration is very fine and somewhat dense, below very sparse, the seg- 

 ments with a subapieaJ line of very distinct punctures and about one- 

 fourth of the length at the exitreme base smooth and shining. Ventral 

 segment T with a median dentiform tubercle, ventral segment II inflat- 

 ed to a blunt central pdint. 



Legs black to piceous, with veFow marks on the tibiae outwardly 

 and covered with a minute dense pale pubescence. Tarsi largely fer- 

 ruginous. Tibiae without sniall spines on the outer surface. 



Wings unevenly smoky, very deeply iso in the marginal cell, the 

 nervunes very dark. Second cubital cell nuich longer than third on 

 the cubital nervure. Third abscissa of radius about as long as first two 

 toge/tber.

5792 Hypomellinus flavicomls n. sp. 



A slender medium siaed species, with the yellow markings predomi- 

 nant, the antennae pale reddish yellow, the wings pale fuscous. 



Male: — Length 10.. "50 mm. Pubescence pale, very finely and closely 

 appressed over the whole body. 



Head as broad as thorax, the eyes not eniarginate above, rather 

 strongly oonv^reent below. Head with larger scattering puncttrres on 

 a very finely and densely punctate surface, the larger punctures disap- 

 pearing on the sides of face and supraclypeal area but present on 

 clypeus. Upper inner angles of eyes with the sides standing at right 

 angles. Face below anteiunae, narrow orbits except above, and man- 

 dibles except at tips, yellow. Antennae reddish throughout, the eight li 

 flagellar article lengthened and the 9th and 10th broadly excavated 

 below. 



Tliorax sculptured like the head above, the finer punctnratioii becom- 

 ing obsolete on the pleurae. The niesopleurae aire bordered in front 

 and below by a foveolated groove, the broad shallow furrow between 

 meso and metapleurae uniform throughout and carinately rimmeil. 

 LTpper area of metanotum bordered by foveolated grooves with many 

 small oblique grooves on the sides and with the median groove slender 

 and terminating in a large irregular centraJ fovea. Posterior portion 

 of metanotum with the median groove becoming smaller, the petiolnr 

 area and sides of metathorax rugose. The yellow markings on the
