NEUROPTERA. 405 
To the localities given, add :—Maexico, Bafios de Santa Rosalia (ib¢d.: 2 3,2 2). 
The pruinose males of this species, as I saw them flying over a small marsh at Santa 
Rosalia, reminded me strongly of Libellula exusta of the eastern United States. 
DYTHEMIS (p. 271). 
Dythemis velox (p. 272). 
To the localities given, add :—Costa Rica, Jesus Maria [3 ¢ ], Rio Machuca [6 ¢, 
2 2] (Biolley, colls. A. N. S., Wilmsn.). 
Dythemis maya (p. 275). 
The supplementary male has the internal triangle on the front wings 4-celled. The genital hamule of this 
species is two-branched, the external branch being very much shorter than the internal, as shown in our 
fig. 45, Tab. VIIL., from the type from San Gerénimo. 
The female from Tepic has the costal edge of the stigma, front wings, 4 mm. long, thus diminishing the force 
of one objection, suggested on page 276, to regarding these males and females as conspecific ; 17 antecubitals 
and 11 posteubitals on left front wing, 7-8 marginal cells in the post-triangular field and the internal 
triangle 3-celled on both front wings, 11 postcubitals on the hind wings, the increase from 2 to 3 post- 
triangular rows on the right hind wing taking place at the level of separation of principal and median 
sectors, hind wing 39 mm. long. 
To the localities given, add :—MeExico, Tepic [1 ¢], Hacienda San Marcos [1 ¢ | 
in Jalisco (Goldsmith, M. C. Z.). 
Dythemis cannacrioides (p. 276). (Tab. X. fig. 13.) 
The new figure is to replace that of Tab. VIII. fig. 43. 
BRECHMORHOGA (p. 277). 
A new species, B. tepeaca, here recognized, will fall in our synopsis, p. 279, between 
C and CC, so that CC should be marked CCC and the following new rubric 
introduced :— 
CC. Hind wings with 3 rows, followed by 2 rows (3), 3 rows (?) between the 
proximal subbasal sector and the wing-margin, &c. (for other details, see the 
description, infra) . 6 6 6 ee ee ee ee ee ee ee ee bepeatca. 
Brechmorhoga vivax (p. 280). 
To the localities given, add:-—Costa Rica, Surubres near San Mateo (Brology, 
A. N.S.: 1 2), Juan Vifias (Cary, U. 8. N. M.: 1 3). 
Brechmorhoga precox (p. 281). 
Strike out Cuernavaca from the list of localities given, but add :—Hownpuras, near 
San Pedro Sula (L. A. Williamson, coll. Wilmsn.: 1 ¢ ).
