Hab. Mexico}, Atoyac in Vera Cruz (Schumann), Teapa in Tabasco (H. H. Smith) ; 
Costa Rica, Caché (Logers). 
Apparently a common insect where it occurs, a large series of specimens of both 
sexes having been received. Bigot’s description ( ¢ ) leaves no doubt as to the identi- 
fication of this handsome species ; he, however, gives the length as 11 millim., whereas 
the specimens before me measure only 6:0-7°5 millim. I may add the following 
particulars:—The third antennal joint is oval and the arista short-plumose. The 
black spots on the front are often very large ; beneath the shoulders is a whitish spot; 
the abdomen is mostly shining bluish-black ; the front cox have a white reflection ; 
the front tarsi have not only the first joint, but the second also white; the middle and 
hind tarsi have not always the first joint clearer than the rest. The brown central 
band of the wings is rather narrow and does not reach the small cross-vein ; the border 
at the tip of the wing is often pale. The small cross-vein is beyond the end of the 
first vein and beyond the middle of the discal cell; the second vein ends in the costa 
a little beyond the posterior cross-vein; the third basal cell is elongate and pointed at 
a short distance from the hind border. ‘The male genitalia are long, the furcate 
projection rufous; the ovipositor of the female is long and pale rufous. 
16. Calobata stellata, sp. n., 2. 
Brownish-rufous with white reflections, and black spots on the head and thorax ; abdomen black; legs brown, 
the femora with white rings, the front tarsi white; wings with two brown bands. 
Length 4°5 millim. 
Head rufous, with white reflections; front with a rounded, black, central spot and two smaller brown dots 
before the antenne. Antenne rufous; third joint oval, infuscated at the tip; arista bare. Thorax 
brownish-rufous, with white reflections; three black dots placed close together on the prothorax and an 
irregular black spot at the sides ; hind portion of the thoracic dorsum blackish; scutellum black ; pleure 
and metanotum whitish-grey ; abdomen, including the long ovipositor, shining black. Legs brownish ; 
all the femora have a whitish base and a white, brown-bordered ring beyond the middle; the front tarsi 
are entirely white. Wings hyaline, with a broad blackish cross-band extending from the costa to the 
fifth vein, and a brownish border at the tip; small cross-vein beyond the end of the first vein and on 
the middle of the discal cell ; end of the second vein a little beyond the posterior cross-vein ; first posterior 
cell attenuated towards the tip, but not closed ; third basal cell elongate and pointed. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
A single female specimen. 
CARDIACEPHALA. 
Cardiacephala, Macquart, Dipt. Exot. 11. 3, p. 242 (1843). 
This genus, used by Macquart for Calobata longipes (Fabr.), is recognizable, among 
other characters, by the four posterior femora having a swelling beyond the middle.
