504 SUBFAMILY X. CURCULIONIN^E. 



XVI. PSEUDOACALLES gen. uov. (Gr., "false" -f- Acalles.) 



As pointed out by both LeConte and Casey, Acalles nuclialis 

 Lee. differs from other members of that genus too greatly in ab- 

 dominal structure and other characters to allow its retention 

 with them; it having the mesosternum feebly emarginate; epis- 

 terna of the metasteruum distinct and parallel ; beak more slen- 

 der and differently sculptured; second ventral twice as long as 

 third, the latter equal to fourth; last joint of tarsi longer and 

 claws larger. From Camsfcs, to which it is closely allied, it 

 differs in its anuulated antennal club and normal tibiae. (W.

794 (8772). PSEUDOACALLES NUCHALIS Lee., 1876, 244. 



Oval, very robust. Blackish, clothed with dark and pale brown scales 

 intermixed, the latter covering the head and forming three indistinct pale 

 lines on thorax; elytra with an angulated transverse pale line near apical 

 third, behind which the yellowish-brown scales are more numerous; under 

 surface nearly black, with scattered pale scales. Beak strongly punctured, 

 deeply striate near base, finely carinate. Thorax two-thirds wider than 

 long, sides almost parallel from base to middle then rapidly narrowing to 

 and feebly constricted near apex; disc coarsely and densely punctured, 

 with a slight trace of a median smooth line. Elytra oval, sides much round- 

 ed, obliquely narrowed behind; disc with rows of large, quadrate punctures; 

 intervals wide, convex, each with a row of rather long, pale, clavate bristles. 

 Under surface nearly black, with scattered pale scales. Length 3.8 4 mm. 



Dunedin, Fla., April 3; Biscayne Bay, July 27. Known also 

 from Capron, Enterprise and Sand Point. In Leng collection 

 from South Carolina. 



XVII. GERST.ECKERIA Champ., 1905. (In honor of Gerstrecker. ) 



Large, robust species, possessing the characters given in 

 generic key, and having the beak at least as long as thorax, the 

 antenna? inserted near its middle with their grooves directed at 

 lower corner of eyes; elytra without humeri; femora unarmed. 

 All the species feed upon cacti. About 22 species have been de- 

 scribed from Central America, Mexico and the United States, 

 only three of which are known from our territory. The latest 

 paper on them is by 



Pierce, W. D. "The Cactus Weevils'' in Proc. U. S. Nat. Mus.,
