Dec, 1908. "J SCHAEFFER : NEW RHYNCHOPHORA. 221 



Chiricahua Mts., Arizona (E. A. Schwarz). 



Very closely allied to icorice but the thorax, especially in the male, 

 is wider and more strongly asperate. 



A single female from the Huachuca Mts., has the striae more 

 deeply impressed and the median row of punctures on each interval 

 strongly muricate, but does not seem to differ otherwise. 



Chramesus dentatus, new species. 



Narrower than icoriic, color black, elytra and legs brown, antennae paler; elytral 

 intervals with sparsely placed, rounded, pale scales, and each with a row of erect, 

 longer scales. Head in the male broadly impressed ; surface finely reticulate and 

 clothed rather sparsely with cinereous hairs ; apex of beak with a conical tubercle at 

 middle ; the female has the front rather flat, surface reticulate and sparsely punctate ;, 

 from each puncture arises a scale like hair, at middle a round, fovea like puncture 

 and like the male at apical margin a small, conical tubercle. Prothorax wider than 

 long; sides broadly rounded, convergent to apex which is scarcely constricted; base 

 as usual, bisinuate ; surface reticulate, with not densely placed, rather large punc- 

 tures, which are strongly muricate at sides. Elytra scarcely wider at base than the 

 thorax ; punctate-striate, striae not deeply impressed ; intervals feebly convex and 

 sparsely punctate. Body beneath sparsely clothed with cinereous hairs which are at 

 apical margins slightly stouter. Length 1.75 mm. ; width 1 mm. 



Huachuca Mts., Arizona; breeding abundantly in oak twigs 

 girdled by Oncideres quercus. 



An easily known species by its relatively elongate form, the con- 

 ical tubercle at apex of beak and the smaller antennal club. 



Chramesus subopacus, new species. 



Form of icorice but much larger ; color black, antennae and tarsi testaceous ; 

 moderately densely clothed above with cinereous or yellowish-cinereous appressed 

 scales, which are smaller and rounded on the elytra and each interval with a row of 

 short-erect, larger scales. Head in the male rather deeply excavated ; side-margins 

 slightly below the middle of the eyes suddenly raised ; shining in a subtriangular 

 apical space ; above this the surface subopaque and finely reticulate-punctate ; in the 

 female the head is somewhat convex, finely reticulate and sparsely punctate, dull ; 

 apical and side margins distinctly beaded. Prothorax wider than long ; sides rounded ; 

 base much wider than apex ; the latter scarcely constricted ; disk not densely punc- 

 tate, at sides a few asperities. Elytra as wide as the prothorax ; basal margin 

 strongly carinate ; sides nearly parallel; apex broadly rounded, punctate-striate; 

 striae feebly impressed, punctures moderate; intervals moderately wide and nearly 

 flat ; the row of median punctures from which the erect setoe arise, the three or four 

 near suture very strongly muricate in the female. Underside sparsely clothed with 

 cinereous hairs, apical margin fringed with a row of pale setce. Length 2.25 mm.; 

 width 1.5 mm. 



Huachuca Mts., Arizona. 



The description of the Central American tumidulus fits this species
