ox SOME NORTH AMERICAN SPECIES OF CHARTERGUS 



BY P. CAMERON. 



4847 Chartergus arizonaensis sp. nov. 



Black, densely eovered with a white silky pile and more sparsidy 

 with short white pubescence; a narrow line in the center of the pro- 

 pronotuni. a narrow one on the apex oit the firs-t ahdoniinal segment 

 and broader bands on the other segments, pale yellow; wings fulvous 

 hyaline, the apex smoky from the end of the stiguna; the stigma, 

 costa and basal nervures bright rufo.fulvous, the apical nervures 

 bright rufo-fulvous, the apical nervures black. Female. Length t 

 en'd of second abdominal segment 7 mm. Collected by Oslar at Noga- 

 les, Arizona. 



Clypeus distinctly wider than long, shining, sparsely but somewhat 

 strongly [umctureil. Front and vertex strongly, moderately closely 

 punctured; the part between the antennae is more weakly punctured 

 above and is keeled in the middle; the lower part is smooth. Hinder 

 ocelli separated from each other by a slightly less distance than they 

 are from the eyes, which are shortly pubescent. Occiput weakly, the 

 ciheeks strongly,, keeled. Temples above as long as the second and 

 third antennal joints united. Scutelium strongly punctured; its apic- 

 al slope steep, smooth and shining; its apex above is not quite trans_ 

 verse; the postscutellum has the sajme slope, is smooth, above broadly 

 dilated in the middle, not transverse like the apex; the sides of 

 the metauotum above the middle project into a distinct bluntly round- 

 ed tooth or projection. First abdominal segment minute, rounded at 

 the base. Second abscissa of rsdius one fourth the length of the third. 

 Mandibles rufous, behind the teeth. Third antennal joint about one- 

 fourth longer than the following. 



Tn Mr. Ducke 's table his Sii)ecies runs near to C. critellus Fox, cf. 

 Bolet. d. M;useu Goeldi, IV, '329. C. aztecm Cam., is not unlike it; 

 it is stouter, is densely pilose am"! haired all over; the angles of the 

 metauotum are differently formed and much larger, becoming gradual- 

 ly wider towards the point, from the base and apex, the terminal 

 point not being separated, in orizonensis the lower part, below from 

 the base, forms a distinct tooth. 



The discovery of this species in the Fniteil States is of much in. 

 terest as the genus Chartergus has not hitherto been recorded further 

 north than Mexico, nor is it known in the West Indies. 

 484fi Chartergus centralis sp nov. 



Black; the apex of the first abdominal segment narrowly, the apices 

 of the others more broadly pitie or orange yellow; body covered with 

 a silvery pile and densely with short white pubescense; wings fulvous
