pairs of the dorsocentral elements are rather long. All 

 lateral bristles are light brownish red and consist of 1 

 notopleural, 1 posterior, 1 supraalar, 1 postalar, and no 

 scutellar bristles. The disc has only golden pubescence, 

 the margin with a pair of short, delicate hairs. Meta- 

 notal slopes micropubescent only ; pleuron everywhere 

 brownish golden pubescent. Metapleuron with an 

 oblique row of 7 moderately long, curved bristles. Pro- 

 notum with 2 or 3 pairs of weak, reddish bristles. 

 There is no pile on the mesopleuron, sternopleuron, 

 pteropleuron, or hypopleuron. Lateral metasternum 

 with 5 or 6 long hairs; postmetacoxal area membranous. 



Legs : The hind femur elongate, rather slender on the 

 basal two-thirds and slightly thickened towards the 

 apex; it bears scanty, short, appressed, brownish yel- 

 low pile and short but rather strong bristles. The leg 

 bristles consist of a lateral row of 3 from the middle 

 outward, 1 medially near the apex and a dorsal pair 

 close to the apex; ventrally there are no bristles and 

 almost no pile, only 3 or 4 minute hairs. Hind tibia 

 slender but somewhat expanded near the apex, with 

 quite short, appressed, reddish yellow pile and with 

 rather longer stout bristles, 1 lateral at the apical fourth, 

 2 ventrolateral at middle and apical fourth, and 4 dorsal 

 bristles from near the base to the apical fourth. Mid- 

 dle femur with 1 rather strong bristle at the subapex 

 both anteriorly and posteriorly and 1 short, strong 

 anterodorsal bristle quite at the apex. Tibia with 

 rather long bristles, 3 anterodorsal, 3 posterior and 2 

 ventral bristles from beyond the middle and at the 

 outer fifth. Anterior femur with short, stout bristles 

 near the apex posteriorly and nearer the apex ante- 

 riorly. The tibia has 3 or 4 rather long, stout, posterior 

 bristles, 2 or 3 minute, short, dorsal bristles, and the 

 apex anteriorly with 1 extremely long, stout bristle, 

 almost as long as the basitarsus; also 4 short ventral 

 and 1 short posterior bristles. No spine present. Basi- 

 tarsus slightly lengthened, a little longer than the next 

 two. Claws only moderately sharp, chiefly curved on 

 the outer third. Pulvilli nearly as long as claws. The 

 empodium strongly swollen at the base and nearly as 

 long as pulvilli. 



Wings: The wings are broad; marginal and all the 

 posterior cells and the anal cell widely open. Second 

 basal cell ends in 3 veins, the middle vein short. An- 

 terior crossvein enters the discal cell at the middle. 

 Base of second posterior cell wide, especially anteriorly ; 

 the anterior branch of the third vein ends at apex. 

 Alula present. 



Abdomen: The abdomen is somewhat flattened on 

 the middles of the first 3 or 4 tergites; sides nearly 

 parallel in the male as far as the end of the fifth; first 

 tergite about one-sixth as long as the second, with a 

 few hairs laterally and 2 or 3 stout but rather short, 

 reddish bristles; other tergites without special pile or 

 bristles ; the pile is very scanty, suberect, and short, In 

 the male seven tergites visible, the sixth tergite is 

 nearly as long as the fifth, the seventh is about half 

 as long as the sixth, and there is a trace of the eighth 

 tergite visible on the left. In the female eight tergites 



are present, the eighth is three- fourths as long as the 

 seventh, shining black and bears 4 or 5 pairs of hol- 

 lowed, reddish brown spines. Male terminalia rather 

 large, elongate and conspicuous. It is not rotate; the 

 epandrium is long, slender, fully cleft but apposed and 

 extending considerably beyond the other structures. 

 Proctiger prominent. Gonopod long, with a narrow, 

 apical dorsal prong. Hypandrium short but large and 

 broad with transverse margin. The aedeagus is particu- 

 larly large, long, curved and conspicuous, arched down- 

 ward and upward to the apex of the proctiger. The 

 cavity is largely open. 



Distribution: Australian: Harpagobroma fumosa, 

 new species. 



Harpagobroma fumosa, new species 



Length 10 mm. Male, female. Head: The face is 

 densely golden micropubescent with the mystax pale, 

 brownish white. The pile of the occiput and proboscis 

 is golden; the occiput on the upper half has 13 mod- 

 erately stout, yellowish bristles, situated in a straight 

 row not very far from the eye margin, and a lower, 

 medial cluster of 2 or 3 bristles near the lateral midpoint 

 of the occiput. Sides of front with 3 weak, yellow bris- 

 tles. Ocellarium with 2 pairs of short, not divergent, 

 yellow bristles, slightly curved forward. Antenna 

 with first segment yellowish brown, the second darker, 

 the third segment black; pile and bristles of antenna 

 reddish yellow. 



Thorax: The thorax is browish golden micropubes- 

 cent to pollinose, including the whole of the pleuron; 

 bristles light browish red. 



Legs: The ground color of the legs is dark, the 

 bristles and pile reddish yellow. 



Wings : The wings are tinged with pale, smoky brown. 



Abdomen : The first seven tergites are brownish red 

 or orange, the eighth is shining black. The pile of 

 the abdomen and the bristles of the first tergite are 

 reddish yellow. 



Type. Male, from Cairns, Queensland, Australia, 

 1907 ; allotype, female, from Palmerston, New Zealand, 

 December 1908. Both are from the Hermann collection 

 and were loaned by Dr. Forster, Director Zoologische 

 Staatssammlung, Munich, to whom the author is greatly 

 indebted for his kind assistance in the loan of material 

 for the preparation of a revision of genera of Asilidae.

Grypoctonus Speiser, Schrift, phys. — okonom. Ges. Konigsberg, 

 vol. 65, p. 155, 1928. Type of genus: Grypoctonus aino 

 Speiser, 1928, by original designation. 



Flies of medium size which are characterized by their 

 very dense, long, fine pile, so dense over areas as to 

 obscure the ground color. Related to Crytopogon Loew 

 and Oldroydia Hull and distinguished from all pres- 

 ently known genera by the presence of the auxiliary 

 crossvein in the first submarginal cell, making two
