C. fallax before me vary greatly in size and colour, the female from Chontales having 

 the elytra rufo-testaceous, while the example from St. Vincent is a small poorly- 

 developed male. The male of C. nasalis has the posterior tibise curved and furnished 



with a dense fascicle of long fulvous hairs on the inner side near the base, and the

PSEUDEUCOPTUS, sp, n. 



Head strongly exserted, porrect, cylindrical, constricted on each side posteriorly, the eyes transverse, depressed, 

 and distant from the base ; rostrum stout, nearly twice as long as the exposed portion of the head, slightly 

 widened at the tip, and with small tuberculiform pterygia, the aerobes extending backward to the eyes? 

 the antennae inserted at about the middle, the funiculus 7~jointed,the club rather small, acuminate-ovate* 

 abrupt; prothorax elongate, constricted and tubulate in front, truncate at the base, and with the disc 

 very broadly depressed down its entire length ; scutellum subtriangular, large, flat ; elytra elongate, 

 subparallel, not wider than the prothorax, broadly flattened ; coxse widely separated, the anterior pair 

 especially ; presternum much longer than the moderately elongate metasternum, and with a transverse 

 sulcus between the coxse ; ventral segments 1 and 2 connate, the suture between them almost obliterated : 

 legs short and stout ; femora strongly clavate and compressed, slender at the base ; tibiae with a Ion

claw at the outer apical angle, the anterior pair angularly dilated on the inner side at about the middle, 

 the others triangular; tarsi with joints 1-3 equal in length, 3 simple, 4 comparatively stout, barely as 

 long as 2 and 3 united, the claws minute, free ; body strongly depressed, very elongate, narrow, almost 



glabrous. 

 Type, P. macrocepTialus. 



This genus is perhaps nearest allied to the Tropical- American Eucoptus, Woll., but 



J. Ill© b 



the unique insect referred to it is more like a Catolethrus, with the body flattened as 



■ 



in the eastern hotroqus. It is remarkable on account of its long, porrect head, 

 unusually elongate prothorax, short, stout legs, and very depressed body. The type is 

 probably a male, and the female may have a more slender rostrum. Eucoptus extends 

 to Cuba, but it is not represented in the Central- American collections before me. 









l. Pseudeucoptus macrocephalus, sp. n. (Tab. I. fig. 31.) 



Moderately shining, black, the antennae, knees, tibiae, and tarsi piceous or fusco-ferruginous, the tip of the 

 rostrum and the outer half of the disc of the elytra rufescent. Head very sparsely, minutely punctate, 

 the rostrum closely, subrugosely punctured in its basal half, becoming much smoother at the tip. Pro-

apical portion ; very finely alutaceous and with minute scattered punctures, the depressed disc with a distinct 

 narrow median groove anteriorly, which becomes obsolete towards the base. Elytra less than twice the 

 length of the prothorax, conjointly rounded at the apex; shallowly striate, the striae feebly punctate, the 

 interstices flat, alutaceous, and obsoletely uniseriate-punctate. Beneath sparsely, finely punctate ; first 

 ventral segment almost unimpressed, the fifth transversely depressed posteriorly.
