 posterior process and hyahne tegmina with straight apical veins Head subquadrate, broader than 

 high; base nearly straight; clypeus very slender, extending for two-thirds its length below the iiiferior 

 margins of thegense; ocelH small, inconspicuous, somewhat elevated, equidistant from each other and 

 from the eyes and situated about on a hne drawn through centers of eyes. Pronotum rough convex 

 rounded; metopidium straight; humeral angles weak, rounded; no suprahumerals or other anterior 

 processes; posterior process slender, straight, often slightly depressed at base, tip acute and reaching 

 just to internal angles oftegmina; scutellum entirely covered by pronotum. Tegmina entirely free

 broad. Legs simple; tarsi uniform in size.

46. GENUS BRACHYTALIS Metcalf and Bruner 



Brachytalis Metcalf and Bruner, Memb. Cuba 2o5 (1925). 



Characters : Very small, shining insects with broad bodies and semiopaque tegmina, resem- 

 bHngin general facies the forms of the genus ^cw/rtto of the subfamily Smiliinse but of course immediately 

 distinguished from that group by the truncate base of the median apical cell of the tegmina and the con- 

 cealed scutellum. Head subquadrate, twice as broad as high, with the eyes extending as far laterad as 

 the humeral angles; base weakly sinuate; eyes large and prominent; ocelli about equidistant from each 

 other and from the eyes and situated near the base of the head well above a line drawn through centers 

 of eyes; clypeus broad, somewhat deflexed. extending only slightly below the inferior margins of the 

 genas. Pronotum broad, depressed, smooth and shining, very Hghtly punctate and not pubescent; meto- 

 pidium sloping, broader than high; humeral anglcs broad, triangular and blunt ; no supiahumerals or 

 other anterior processes; posterior process straight, rounded above, short, just reaching the apical end 

 of the clavus; median carina faintly percurrent ; scutellum entirely hidden by the sides of the pronotum.
