NO. 1889. DESCRIPTIONS OF ECONOMIC WEEVILS— PIERCE. 159 



connate, tho suture slightly arcuate and indicated by a smooth line; 

 remaining segments shorter, the fourth being shortest. 



2Iale. — The male generic characters differ as follows: Beak more 

 robust, slightly shorter, almost straight; scrobes beginning at apical 

 fourth, straight, and directed at eyes. Antennal scape inserted at 

 or slightly beyond middle of beak, reaching eyes; eyes separated by 

 about one-half the width of the beak below and by slightlj" less than 

 the width of tho beak above. Pygidium arcuately truncate at apex. 

 First two abdominal segments connate, suture angulatc at middle. 



Genotype. — Ecthetopyga gossypii, new species. 



ECTHETOPYGA GOSSYPII, new species. 



Described from three females and two males taken from a series 

 collected by C. S. Banks on cotton plants from the island of Negros, 

 Philippine Islands (Banks No. 883). 



Length, 3-3.5 mm.; breadth, 1.75 mm. Broadh' oval, compressed, 

 tnincate behind. Color dark brown, \\Titli fine golden pubescence, 

 head and beak almost black, underside lighter bro%\-n, legs and 

 antennre still lighter. 



Female. — Beak evenly sculptured with oblong punctures, not pubes- 

 cent. Front with a short longitudinal fovea; finely, evenly punctured, 

 finely pubescent between eyes. Prothorax finely, closely, and evenly 

 punctured and pubescent. Elytral striae consisting of deeper close-set 

 punctures, but not depressed; intervals closely, finely, and evenly 

 punctured. Underside lighter throughout, punctuation and pubes- 

 cence sparser. Coxse and legs yello\\'ish, punctured and pubescent; 

 femoral teeth about equal; tarsi spongy underneath; tarsal claws 

 moderately large, slender, strongly divergent, basally toothed. 



Male. — Beak flattened, apically enlarging, laterally and medially 

 tricarinate, rugosely oblongo-punctate. Front foveate. 



In form this species resembles very much Miarus and Gymnetron, 

 but the antennal and ungual characters readily separate it. No 

 nearly related American species are kno\\'n. 



Type.— Cat. No. 14469, U.S.N.M. 



2. THE CACTUS WEEVILS. 



In view of the approaching publication of a bulletin on cactus 

 insects by W. D. Hunter, J. D. Mitchell and the late F. C. Pratt, the 

 writer has been requested to make a critical study of the cactus 

 weevils formerly grouped under the genus Acalles. In view of the 

 description of another species in the same subtribe. it is pertinent to 

 present herewith a table of the genera of the subtribe Tylodina. in 

 the subfamily Cryptorh^Ticliinae now known to occur in the United 

 States.
