vein, the latter joining and forming almost a right angle with 
the posterior cross-vein. 
Halteres pale, with fuscous knob. 
Length.—8 mm. (of mid legs 18 mm., of wings 9 mm.). 
Habitat. —Mexico. 
Observations .—Described from a single 9 i n the British • 
Museum collection. It is a very distinct, rather iridescent, 
yellowish-looking, large species, with venation like a typical 
Megarhinus, but with no caudal tuft, with pale olive-green 
abdomen, except the first segment, which is pale blue. It 
shows considerable variation in colour when held in different 
directions, but its large size and general yellowish hue and 
absence of caudal tufts should at once separate it, as well as its 
long spider-like legs. 
This species may belong to my genus Toxorhjnchites, as I am 
not certain from a single specimen if the palpi are broken or not ; 
they appear as if broken.

“Proboscis strongly built, long; thorax fuscous, with golden-green 
scales ; the two last segments of the abdomen with dense lateral hairs, the 
three front segments metallic green, the rest blue; anus with golden- 
yellow hairs; legs black, all the tarsi broadly banded white; anterior 
margin of the wings blue scaled. Length, 2\ lines.” 
The two not particularly good species examined bear a strong 
resemblance to M. amboinensis, but may readily be distinguished from 
that species by the following characters. Palpi of the $ short, curved 
upwards, slightly hairy, and like the eyes and antennae black. Posterior 
border of the head metallic green; thorax high and oval, prothoracic lobes 
dark brown, ornamented with shining golden-green scales; scutellum and 
first three abdominal segments green. Last two segments of the 
abdomen armed on either side with long black hairs, mixed with a few 
white ones, 4th to 8th segments blue, the end of the abdomen with 
orange-coloured hairs. Legs black, long, not very hairy. In the fore and 
hind tarsi there is one white band, two to the middle pair. Wings shorter 
than the abdomen, with dark brown veins, the anterior border partly 
ornamented with green scales. Amboina, less common than M. 
amboinensis .—(Description from Nat. Tijdschr. v. Ned. Indie, xiv. p. 382.) 
Note.— This species, if the 9 palpi are short, not broken, 
comes in my genus Toxorhyncliites. —(F. V. T.)
