SPILOGRAPHA. AQT 
Front rufous, as broad as the eyes, posteriorly slightly enlarged, on the vertex very shining ; frontal and post- 
vertical bristles black ; face and cheeks pale yellow; the face perpendicular ; cheeks broad, their inferior 
part as high as half the longitudinal diameter of the eyes; oral margin broad, not prominent; occiput 
swollen, in the middle dark rufous, at the sides paler. Antenne rufous; third joint elliptical, not 
reaching half the length of the face; arista brownish, pubescent. Proboscis brown; palpi rufous. 
Thoracic dorsum obscure cinereous, with three narrow brown lines; shoulders and pleure rufous; a 
yellowish-white stripe from the shoulders to the root of the wings; scutellum brown, with four long 
bristles; metanotum black. Abdomen slightly convex, black, with grey hind-borders to the segments ; 
tip of the anal segment rufous. Legs rufous; the femora, except at the tip, blackish. Halteres rufous. 
Wings longer than the abdomen, hyaline, with four somewhat irregular brown cross-bands: the first, near 
the base, immediately beyond the humeral cross-vein, covering the base of the basal cells and bordering 
the sixth vein; the second band has its origin in the more obscure stigma and runs in an oblique direction 
over the small cross-vein and through the discal cell to the posterior margin ; the third band begins on 
the costa at the tip of the second vein, borders the posterior cross-vein, and would form with the second 
band a V-like figure, if it was not interrupted in the first posterior cell; the fourth cross-band forms a 
rather short border at the tip of the wings; between the second and third cross-bands there is also 
a brown stripe, reaching from the costa to a little beyond the second vein; the small cross-vein is on the 
middle of the discal cell. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (Hl. H. Smith). 
A single male specimen. 
3. Spilographa latifrons, sp.n..¢. (Lab. XI. fig. 26, wing.) 
Thoracic dorsum cinereous; head, pleure, and legs rufous ; abdomen blackish, with rufous tip; front broad; 
wings with brown cross-bands. 
Length 5°25 millim. 
Allied to the preceding species (S. obfuscata), and agreeing with it in most respects. The front is much broader 
than the eyes, with parallel sides, on the vertex with three shining spots. Face slightly retracted ; 
inferior part of the cheeks as long as one-third of the longitudinal diameter of the eyes. Antenne a 
little longer than in S. obfuscata. Scutellum and metanotum rufous. The rufous coloration at the tip of 
the abdomen has a larger extension. The femora are not blackish, but rufous, like the rest of the legs. 
The venation and pattern of the wings are quite similar to those of S. obfuscata, but the third cross-band 
is complete and not interrupted in the first posterior cell. 
Hab. Mexico, Ciudad in Durango 8100 feet (Forrer). 
A single male specimen. 
4. Spilographa rufata, sp.n..¢ @. (Lab. XI. fig. 27, wing.) 
Rufous; anal segment of the male with two black spots ; wings hyaline, with interrupted brownish cross-bands : 
face perpendicular. 
Length 4-5 millim. 
Of a general rufous coloration, including the antenuz, proboscis, palpi, and legs. Front as broad as the eyes, 
slightly enlarged towards the vertex ; ocellar tubercle blackish, on each side of it a shining spot; frontal 
bristles black. Face and cheeks yellowish; face perpendicular; cheeks broad. Second joint of the 
antennew with a short bristle; third joint elliptic, reaching half the length of the face; arista black, 
subpubescent. Anal segment in the male with two lateral black spots (in one of the specimens the 
abdomen shows traces of a more extended blackish coloration); ovipositor of the female short, its first 
joint black, the second rufous, lanceolate. Wings much longer than the abdomen, hyaline, with a fuscous 
pattern, very similar to that of Spilogrupha (dacarena) tetanops, Low (Monogr. Dipt. N. Amer, iii. t. 11. 
fig. 15), but the cross-bands are incomplete, being more or less interrupted, and the apical spot is concave
