CNEOGLOSSA.— DICKANOPSELAPHUS. 595 



The epistoma is prolonged beneath, and there is no visible labrum, the head being 

 formed very much as in the species of the group Macropogonini of Horn. 



1. Cneoglossa lampyroides. (Tab. XXVI. fig. 11.) 



Elongate-oval, rather depressed, shining ; brownish-black or fuscous, the prothorax dilute yellow or reddish- 

 yellow, with a black median vitta, the sides semitransparent, the antennse black, with the two basal 

 joints usually reddish, the legs piceous or brownish, with the base of the femora, the knees, and tarsi 

 sometimes paler ; thickly pubescent, the hairs on the elytra brown or brownish-cinereous and rather 

 coarse. Head very minutely punctured ; antennas— ( d ) more than half the length of the body, broadly 

 dilated and serrate from the third joint, the second joint very small, the third slightly shorter than the 

 fourth— ( $ ) much shorter, with joints 4-11 moderately dilated. Prothorax strongly transverse, widest 

 a little before the base, semicircular as viewed from above, truncate in front and with the base emarginate 

 on either side, concave laterally, the hind angles rather sharp and projecting backwards ; the surface 

 thickly, very minutely punctate. Elytra about four times the length of the prothorax, and a little wider 

 than it, subparallel, the humeri rounded ; rather coarsely punctate-striate, the strife shallow, the inter- 

 stices somewhat convex and densely, rugulosely punctate. 



Length 3|-4, breadth 1|-1| millim. ( <$ $ .) 



Hob. Mexico, Cuernavaca in Morelos (Flohr) ; Nicaragua, Chontales (Janson). 



Six examples from Nicaragua and one from Mexico, representing apparently the 



sexes of one species, as they only differ in the form of the antenna-, the supposed male 



being from Mexico. A Nicaraguan specimen is figured. 



2. Cneoglossa brevis. 



Oblong-oval, feebly convex, shining ; brownish-black, the elytra black towards the apex, the prothorax dilute 

 yellow,' with a black median vitta, the antennse black, with the two basal joints testaceous, the epistoma 

 and legs testaceous ; the elytra clothed with brownish pubescence. Antennae about half the length of the 

 body, the joints from the third broadly dilated and acutely serrate. Prothorax as in G. lampyroides, but 

 more' sparsely and less distinctly punctate. Elytra about three and one-third times the length of the 

 prothorax ; punctate-striate, the stride shallow, the interstices densely, rugulosely punctured. 



Length 3, breadth 1| millim. ( <5 .) 



Hab. Panama, Tole (Champion). 



One abraded example, with the apical three joints of the antennas broken off. Less 

 elongate and smaller than C. lampyroides, the antennas much more acutely serrate from 

 the third joint, the thorax smoother, the elytra shorter, &c. 



Subfam. EUBRIIN^E. 



DICRANOPSELAPHUS. 



Dicranopselaphus, Guerin, Rev. et Mag. Zool. 1861, p. 531 ; Horn, Trans. Am. Ent. Soc. viii. 



p. 97(1880). 



Five species of this interesting genus have been described— four from Mexico and 



one from the United States ; a fifth is now added from Guatemala. The bifid tarsal 



claw is peculiar to the males, the claws being simple at the tip in the females.
