Genus Acartomyia. 255 
scales spreading from the base upwards ; there are three more 
or less distinct dark scaled rings on the long straw-coloured 
joint ; the last two joints and apex of the antepenultimate with 
yellowish-brown hairs; antennae straw-coloured, with rather 
thick, stumpy joints and flaxen plume-hairs, apical joints darker. 
Thorax as in 9°. 
Abdomen with the fifth, sixth, and seventh segments with 
the white basal band projecting in the middle as well as laterally ; 
densely covered with long pale flaxen pubescence. 
Legs much as in the 9; fore ungues unequal, the larger 
biserrated, the smaller uniserrated ; mid ungues unequal, both 
uniserrated ; hind equal and uniserrated. 
Wings with the fork-cells very short, the first sub-marginal 
about half the width of the second posterior, but slightly longer, 
its base a little nearer the base of the wing, its stem about 
two-thirds the length of the cell; stem of the second posterior 
nearly as long as the cell; posterior cross-vein about its own 
length distant from the mid cross-vein. Genitalia shown at 
Fig. 132, e. 
Length.—4°5 mm. 
Habitat. —Malta (Dr. Zammit). 
Time of capture.—July, August and September. 
Observations.— Described from a series sent by Dr. Zammit. 
It comes very near Rondani’s C. penicillaris as re-described by 
Ficalbi. I cannot detect, however, the basal tooth in the mid 
larger ungues of the male, and the genitalia, although very 
similar, presents certain differences to those shown in Ficalbi’s 
figure. The abdominal adornment also differs, especially in the 
absence of the median black line on the venter, and the simple 
basal white bands on the dorsum. 
From pulcripalpis (Rondani) it differs in having distinctly 
clavate ¢ palpi and the g ungues of the fore legs have two 
teeth to the larger one, not one as in pulcripalpis; from 
pulcritarsis by’ the same character of the larger fore ungues, 
having two teeth, not one tooth, and in having an ornamented, 
not unadorned thorax. 
From dorsalis and Spencerit by having the last hind tarsal 
white. This species occurs breeding in numbers in salt pans 
along the shore line, and is found in July, August and September. 
The larvae (fig. 134), which live in salt pans along the shore, 
have long, single-jointed, cylindrical antennae, with short stiff 
spines, and terminate in one long and several short spines, on the
