REVISION OF NEARCTIC TERMITES. - 69 



cubitus ends long before tip, six or seven branched. Body denseh' 

 hairy; that on head dark, on pronotum grayish, on abdomen plainly 

 yellowish to golden. 



Length to tip of wings, 7.5 mm. (Figs. 52 and 53.) 



From Matamoras, Mexico, and Harlingen, Texas, 1st August 



(winged) (Mitchell) ; workers collected by Snyder from Texas as 



follows: Brow^nsville, Cameron County; Victoria, Victoria County; 



San Antonio, Bexar County; and Uvalde, Uvalde County. (Fig. 51.) 



NASUTITERMES, new genus. 



I use this for the Eutermes s. s. of Holmgren, with Eutermes morio 

 Latreille as type. Clypeus several times as broad as long, very 

 plainly bilobed, fontanelle small, elongate, forking below, and some 

 muscular impressions below it more or less distinct, ocelli rather 

 small, hardly elongate; antennae short, with the third joint not 

 noticeably longer than the second or fourth; tibia of front legs with 

 two apical spurs; none on outer side; the hairs below tibia fine, not 

 spine-like. Mandibles moderately short. 



Soldier. — Head nasute, mandibles small; no constriction to head; 

 antennae with third joint a little longer than second. This generic 

 name was used by Dudle}" in 1890, but without mentioning any spe- 

 cific name. I can not fuid that it will agree with any of the numer- 

 ous subdivisions of Eutermes except with Eutermes in the restricted 

 sense of Holmgren. 



NASUTITEKMES COSTARICENSIS Holmgren. 



Adult. — Head and other parts reddish brown; mouth parts, an- 

 tennae, legs, and venter yellowish; all clothed with fuie, yellowish hair. 

 Head broader than long; eyes small, nearly circular; ocelli about cir- 

 cular, scarcely long diameter from the eyes; antennae short; second, 

 third, and fourth joints short, subequal; others beyond scarcely 

 longer, but broader; pronotum about one and two-thirds times as 

 broad as long; front margin hardly concave, but little elevated hi 

 middle; sides rounded behind into the hind margin. Wings absent. 



Length of body, 7 mm. 



Closely similar to N. morio, but not as dark colored, and the ocelli 

 are nearer to the eyes; it is apparently the same as N. sancJiezi of the 

 West Indies, but for the present will keep it separate. 



Soldier. — Head dark brown; thorax and abdomen above brownish 

 yellow; legs pale yellowish. Head pyriform, not constricted; the 

 projection rather long and slender; from the side the head has a nearly 

 straight outline in front; above are several long erect hairs and about 

 four in a transverse row just above base of the beak; antennae 

 13-jointed, third joint a little longer than the second or fourth; body 

 and legs with fine, erect, white hairs. (Fig. 54, 1.) 



Length of head, 1.5 mm.
