ODONTOMYIA. 65 



35. Odontomyia pulcherrima, sp. nov. 



5 . Head distinctly broader than thorax; vertex and frons fully 

 one-third the width of head, the latter slightly wider towards 

 antennae, with short black hairs ; whole head below antennae 

 paler yellow, with soft golden hairs ; antennse black, 3rd joint 

 about 2^ times as long as 1st and 2nd together ; proboscis black ; 

 occiput yellow, blackish in centre ; posterior orbits of eyes 

 narrowly yellow ; vertical triangle black, small ; ocelli pale orange. 

 Thorax with greater part of dorsum down to the suture, except 

 anterior and side-margins, occupied by a large shining black spot, 

 bare except for a broad short stripe of golden pubescence, begin- 

 ning just behind the anterior margin but reaching only halfway 

 to the suture ; on each side behind the suture (just clear of the 

 side-margins) a semicircular black spot (the straight side inwards) 

 and contiguous to the large black spot above the suture, thus 

 leaving an approximately square space occupying more than half 

 the surface behind the suture, and reaching the posterior border 

 of the dorsum with sharply defined sides; this space is reddish 

 brown, and the large anterior black spot just perceptibly encroaches 

 on the anterior margin of it. Scutellum large, reddish brown, as 

 are the spines and the metanotum ; sides of thorax wholly pale 

 yellow with bright golden-yellow pubescence. Abdomen mode- 

 rately shining black, bare ; basal half of 1st segment, a large sub- 

 triangular spot on each side of 2nd extending from anterior to 

 hind margin, an elongate transverse spot towards each side on 

 hind margins of 3rd and 4th segments (those on latter rather 

 smaller), and a long spot narrowed to a point anteriorly on 5th 

 segment, all light yellow. Venter wholly yellowish. Legs with 

 coxae yellowish or yellowish brown, with yellow hair ; front legs 

 black, brown at base of femora ; on apical half of outer side of 

 tibiae a fan-like row of stiff black hairs ; middle legs black, basal 

 half of femora yellowish white, a similarly-coloured band on 

 middle tibiae ; hind legs black, basal half of femora yellowish 

 white. Pubescence on all legs generally concolorous with ground- 

 colour, some fairly coarse black pubescence at base of middle 

 tibia? ; tarsi with golden-brown pubescence below ; pulvilli 

 brownish orange ; claws orange, blai-k-tipped. Wings pale 

 yellowish brown; costal cell and extreme base of wing, also 

 beyond discal cell, pale grey ; stigmatic region blackish brown ; 

 veins dark brown ; 3rd vein forked very near tip ; halteres pale 

 dull yellow.
