white hairs. Remaining segments fringed with yellowish white hairs, 

 except on dorsum, where immediately behind the second segment appears 

 a large triangular patch of black fading towards its apex. Legs dark 

 brown, with sparse, yellowish white hairs; tibial and tarsal spines black. 



Two 9 specimens; San Augustine, on east side of Organ 

 Mountains, N. Mex. , Aug. 29, 1894 (Ckll., 2282); Las Cruces, 

 N. Mex., Aug. 25, 1894 (Ckll., 2036). The first-mentioned now 

 in coll. Am. Ent. Soc. , the other in coll. N. Mex. Agr. Exp. Sta. 



The scarlet color is about the tint of a specimen of -5". occiden- 

 talis from Florida, received from Mr. Fox. Of the species seen 

 by us, none could be compared with heterochroa; and a search 

 through the descriptions fails to bring to light anything which 

 agrees with it, according to our judgment. 



Sphaerophthalma megacantha n. sp. 9- About 13 mm. long; terra-cotta 

 red, with more or less black and pale hairs. Head very large, a little 

 wider than thorax, quadrate seen from above, sides and base meeting 

 almost at right angles; posterior margin below prolonged downwards into 

 a strong spine; vertex and cheeks strongly punctured, terra-cotta red, 

 clothed with rather sparse, appressed hairs of the same color, and scat- 

 tered, erect, black hairs. Face concave; antenna; situated in the con- 

 cavity, dark brown, scape with pale hairs. Mandibles large, tipped with 

 black, their basal portions more or less overlapped by long pale hairs. 

 Thorax broader in front than behind, deeply excavated at sides, posteri- 

 orly truncate; punctures, color, appressed hairs and erect hairs as on 

 head, save on the metathorax, where the black hairs become larger and 

 much more numerous. Abdomen elongate-pyriform, first segment 

 broadly sessile, clothed with erect, black hairs, and a fringe of appressed 

 black hairs extending over its junction with the second segment; second 

 segment covered like head and thorax, with a fringe of black hairs at its 

 posterior margin. Remaining segments red, with fringes of mixed black 

 and pale hairs. Underside of abdomen with pale hairs. Legs shiny, 

 piceous, sparsely clothed with rather long pale hairs. Femora sparsely 

 punctured. 



Hab. Guanajuato, Mexico (Dr. A. Duges). One specimen. 



Sphaerophthalma dugesii n. sp. ?. About 12 mm. long. Brown, pu- 

 bescence variously colored, dull yellow, black and scarlet. Similar in 

 size and structure to 6". sumichrasti (of which we have a specimen, sent 

 by Mr. Fox); and in color intermediate between snmichrasti and hetero- 

 chroa, the head and thorax suggesting the former, the abdomen the latter. 

 Head about as broad as thorax, punctured, clothed, as in sumichrasti^ 

 with pale ochreous pubescence, with a few black, erect, hairs interspersed. 

 Antenna; rather paler than in sumichrasti; brown, darker towards tips, 

 witli some yellowish white hairs on scape. Thorax clothed, as in sunn- 

 chrasti, with black and pale ochraceous hairs, but the disposition of the
