ART. 22 LITTLE KKOWN DIPTEEA ALDRICH 9 



Abdomen mostly black iii ground color, only the first segment 

 conspicuous yellow above and below; the remaining segments are 

 covered with gray pollen which bears numerous large and strikmg 

 dark spots out of wliich the hairs arise; third and fourth segments 

 more convergent than in the male, the latter with a discal row of 

 bristles. In the female the parafacial hairs are sometimes dark 

 colored and then appear quite distinct. 



Length, male 6.5 mm., female from 6-8 mm. 



Described from seven males and five females; three males (mchid- 

 ing type) and four females (including allotype) collected at Cairns, 

 North Queensland, Austraha, m 1918 to 1920, by Dr. J. F. Illing- 

 worth and A. P. Dodd; one male was collected at Gordonvale, North 

 Queensland, Januarv, 1920; two males and one female collected by 

 Edmund Jarvis from "scrub" in the same general region of NortK 

 Queensland. 



Type.— Cut. No. 28883, U.S.N.M. 



As compared with Metallea notata Van der Wulp, type of the genus,, 

 which is identified by Townsend in the National Museum from India 

 and Java, the new species is larger, the whole upper surface is much 

 more sprinkled with dots, and the characteristic deep black spots on 

 the lateral ventral part of the second and tliird abdominal segments 

 are lacking. The genitaha are also quite distinct and the lobes of 

 the fifth sternite in notata do not possess the brushes of spines. The 

 single female of notata in the collection has a subshining translucent 

 region in the lower face including the tranverse impression and the 

 anterior portion of the cheek to a hne extending from its lower 

 anterioT- angle to the lower curve of the eye (this is the Java 



specimen) . 



Mr Malloch informs me that he has identified this species in some 

 of his'recent work, not at present published, as Metallea gracilipalpi^ 

 Macquart (described as Rhyncliomyia gracilipalpis' I hesitate to admit 

 this identification because Macquart's specimen was considerably 

 smaller with wholly vellow abdomen, palpi which to him appeared 

 to be remarkably slender and were so figured, and with, according to 

 his figure, quite an unusual row of vibrissae. 



METALLEA ROBUST A, new species 



i\fale —The front at narrowest twice the width of the ocellar tri- 

 angle; parafacials not quite twice as wide as the front, with numer- 

 ous coarse but short black hah-s. Antennae brownish red, the penul- 

 timate joint longer than in the related species, twice as long aj 

 wide Cheek with pale yellow hair, very conspicuous on the hmd 

 portion and a brown spot on the anterior upper part. Thorax about- 

 the same as in niqriharha, the dorsum being decidedly coppery, the 

 pleural hairs, however, being almost entirely pale as m dhngwortU.
