i58 THE DIPTERA-BEACHYCEEA OF TASMANIA, 



Wings with base, upper and middle basal cells and anterior 

 veins brown; posterior veins indistinct ; from the discal cell 

 the middle veinlet reaches the wing margin indistinctly ; the 

 first and third veinlets are abortive. 



This species bears a considerable resemblance to 0. 

 later emaculata, but may be distinguished by the antennae, 

 which bear a long thin pointed style, instead of a short blunt 

 one, by the much smaller and widely separated abdominal 

 spots, and in the female, by the face being black with a 

 fulvous border instead of altogether fulvous. 



Of this species I have only come across a single specimen , 

 it occurred on fennel bloom at Mangalore, on February 27, 

 1912; it was very active, flying about from one part to 

 •another of the bloom-heads, and only keeping at one spot for 

 a few seconds at a time. 



Odontomyia lateremaculata Macq. 



Abdomen black, with three pairs of green or yellow 

 marginal spots, the first and second pairs large, and usually 

 confluent ; antennae with a short blunt style ; face in male 

 black, in female fulvous. 



Length. Male, 12 mm.; female, 9 mm. 



Hab. Bagdad Valley, Wedge Bay, Lefroy. 



Male. Face somewhat produced, with a rounded outline, 

 black for some distance below the antennae, then fulvous, and 

 covered with yellow pubescence. Eyes bare, joined from 

 vertex to antennae. Antennae black, the third joint slightly 

 tinged with red beneath ; first joint a little longer than the 

 second, third considerably longer than the first and second 

 together, and provided with a very short blunt style, wdiich 

 is only about one-tenth the length of the third joint. Thorax 

 black, with thick fulvous pubescence at sides, scutellnm with 

 base narrowly black, margin broadly yellow; scutellar spines 

 yellow, with the extreme tips black. Abdomen black, the 

 second and third segments each bearing a pair of large green 

 side-spots, which are partially confluent, the fourth wirh a 

 pair of small green posterior side-spots, and fifth with green 

 posterior side margins. Legs with femora black, pale yellow 

 at the base; tibiae black, with a pale yellow band around 

 centre, also with knees of the anterior and middle pairs 

 yellow ; tarsi black, with the first joint two-thirds yellowish. 

 Wings hyaline, the anterior veins brownish ; the middle vein 

 from the discal cell reaches the wing margin, the first and 

 third are abortive. 



Female l>ears a considerable resemblance to the male, but 

 the face is fulvous, being only black for a small patch at base of 

 the antennae. Eyes widely separated. Front directly above
