406 SUPPLEMENT. 
3 (a). Brechmorhoga tepeaca, sp.n. (Jab. X. figg. 55, 56.) 
3. Metallic blue on the superior and anterior surfaces of the frons extending on to the lateral surfaces 
superiorly ; labrum yellow or greenish at base, its free margins bordered with black ; lateral labial lobes 
with mesial half or less brown to black, remainder cream-yellow; the usual pale green antehumeral, 
mesepimeral, and metepimeral stripes on thorax, which, at mid-height, are respectively 3-5, -7—-1, and 
‘5—7 mm. wide; longitudinal pale green stripe on abdominal segment 3 confluent at base with the 
transverse pale green stripe ; each pale dorsal spot on 7 a little more than half as wide as that half of 
the dorsum on which it lies ; genital hamule not so strongly curved, nor so thick at the apex, as that of 
vivax, more strongly curved, thicker at the apex, than that of precow, no posterior process on the genital 
lobe; hind wings with three rows, followed by two rows, of cells between A, (proximal subbasal sector) 
and the hind margin, the change from three to two rows taking place at from 4 to 13 (most frequently 
8) cells from the apex of the membranule, counting along the wing-margin. (In wwaxr 3, precow S, 
and postlobata ¢ the two rows usually begin at 1-3 cells from the apex of the membranule.) 
Q. Differs from the male as follows: metallic blue confined to the superior frontal surface; border of the 
labrum narrower, in some brown ‘rather than black but distinct ; hardly any dark colouring on the 
lateral labial lobes ; vulvar lamina bilobed, lobes almost in contact with each other, each lobe twice as 
wide as long, rounded at its free extremity ; hind wings with three rows of cells for the entire area 
between A, and the hind margin. 
Dimensions —Abdomen, 3 35-40°5, 9 36°5-39; hind wing, ¢ 35-38, @ 37-38; width of hind wing at 
arculus, § 10-11°5, 9 10°5-11, at nodus, ¢ 95-11, @ 10°5-11°5 mm. 
Hab. Mexico, Huatusco [1 ¢ ], Coatepec [Barrett: 1 ¢] and Xico (Calvert: 1 ¢ | 
in Vera Cruz, Cuernavaca [ Barrett: 4 6, 39 +1 pair] (colls. Adams, P. P. C., 
Smyth). 
The examples for which this new name (that of a native tribe of the same region) 
is proposed include those doubtfully referred (anted, p. 282) to “ Intermediates between 
precox and mendaz,” the Cuernavaca specimens cited as precox (anted, p. 282), and a 
few others more lately examined. They seem at least as worthy of a distinctive name 
as some of the other members of the genus Brechmorhoga, and while they may 
ultimately receive that of sallwi, Selys (cf. footnote to page 283, anted), in the present 
state of uncertainty as to what sal/@i really is, a new appellation will avoid confusion. 
‘The Coatepec example is the type of tepeaca.
