98 HEMIPTERA-HOMOPTERA. 
indistinct carine ; tegmina with the radial and interior ulnar veins forked at about an equal distance, 
slightly behind the middle, the granulation not or scarcely evident ; tibie simple. 
This genus is allied to Crrius, from which it may be known by the absence of the 
coarse setigerous granulations of the tegmina, the almost or quite straight hind margin 
of the long and smooth vertex, and the shorter frons and clypeus, which are separated 
by a deeper furrow. 
1. Haplaxius levis, sp. n. (Tab. X. figg. 29, 29a, 6,9; 30, ¢, terminal 
segment of abdomen from beneath.) 
Vertice testaceo; fronte dilute testaced, antice et postice nigro-notata; pronoto testaceo, ad partem infuscato ; 
scutello rufo-brunneo, carinis testaceis, colore variante; tegminibus pellucidis, vena radiali partibusque 
quibusdam venarum aliarum infuscatis ; abdomine testaceo, ad partem nigrescente; pedibus testaceis. 
Mas segmento ultimo ventrali leviter emarginato, processu brevi mediali obtuso, stylis sat magnis, apicibus 
securiformibus rotundatis. . 
Vertex long, with a trace of a carina at the base; forehead light testaceous, with very distinct and regular 
black markings in front and behind; pronotum testaceous, with blackish markings; scutellum variable 
in colour, usually reddish-brown, with the indistinct carinew lighter, sometimes with an infuscate stripe 
on each side of the outside pair; tegmina transparent, with the radial vein and parts of the other veins 
strongly infuscate; abdomen varying in colour; legs testaceous. 
Male with the last ventral segment of the abdomen gently emarginate, with a short, blunt, central process 
and rather large styles, which are dilated and securiform at the apex. 
Long. cum tegm. 5-54 millim.; lat. ad hum. 13-2 millim. 
Hab. Mexico, Mexico city (H. H. Smith). 
Several specimens, including male and female. 
2. Haplaxius frontalis, sp.n. (Tab. X. figg. 31, 31 a.) 
Niger vel brunneus, colore variante; vertice albido vel dilute testaceo; fronte albescenti, nigro et rufo-flavo 
notato; pronoto nigro-fusco testaceo-marginato ; scutello ad latera nigro, ad medium albescente, vel toto 
vel ad partem testaceo-brunneo; tegminibus pellucidis, macula costali excepta, immaculatis, haud 
evidenter granulatis. 
Variable in colour, black or brown; vertex of a whitish-yellow, which is very conspicuous between the dark 
eyes ; forehead whitish-yellow, with the base black and a triangular orange patch just before the clypeus, 
these markings, however, variable and sometimes yellowish-brown; frontal ocellus visible under a high 
magnifying-power; pronotum dark with light margins, or brownish; scutellum dark at the sides, 
yellowish-white in the centre, or uniformly brownish-testaceous, or lighter in the middle; tegmina trans- 
parent, with the veins well-marked, but without spots, except the usual costal patch before the apex ; 
legs light testaceous. 
Long. cum tegm. 43-5 millim.; lat. ad hum. 1-13 millim. (9.) 
Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith). 
There are two insects in our collection, from Teapa in Tabasco, which closely 
resemble this species, and differ chiefly in being entirely of a light testaceous colour 
and in having the veins of the tegmina very delicately but distinctly granulose; they 
may belong to another species, especially as the vertex is rather distinctly carinate at 
the base, but they can hardly be described until more are found.
