STILL ANOTHER APHILANTHOPS. 



BY T. D. A. COCKERELL, MESILLA, NEW MEXICO. 



Aphilanthops concinnnlus, n. sp. — $. Length, 9 mm. Rufous, 

 with white markir.gs, a rather obscure broad black band extending across 

 vertex, including most of the ocelli, its lower margin concave, mandibles 

 darkened towards tips, mid and hind tarsi darkened. The white or 

 yellowish-white marks consist of a small spot on each lower corner of 

 face, a small obscure suffused spot on mandibles near base, the prothorax 

 above, the tegulpe except extreme base, the tubercles, a large patch behind 

 tubercles having a linear oblique projection above, the anterior margin of 

 scutellum, a spot on each side, the postscutellum, spots at the apices of 

 anterior and hind femora, longitudinal bands on all the tibiiB, a large patch 

 on each side of the first three abdominal segments, a band on the fourth, 

 a broad quadrate spot medially on the fifth. Venter immaculate. Face 

 with the usual silvery appressed pile. General structure, wings, etc., as 

 in qtiadrinotaius, but the third submarginal cell is much less produced at 

 its apex, and the third at its base, than in qiiadriiwtatus, this character, 

 however, being liable to variation. The anterior tarsi present numerous 

 gray spatulate hairs. The apex of the abdomen is of the same type as 

 in qtiach-biotatus. 



$ . Length, 8 mm. Black with white markings ; the legs, the first 

 segment of the abdomen, the second and sometimes the third more or less 

 dorsally, the sides of the prothorax and greater part of metathorax some- 

 times, dark rufous. Markings as in $, except that the clypeus is yellowish- 

 white, the anterior and middle femora have a white subapical patch 

 behind, the abdomen above has five continuous bands, the second and 

 third sometimes narrowly interrupted, the venter has three white bands, 

 interrupted in the middle. Apex of abdomen pointed. Scape dark 

 rufous with a pale yellowish ring. Face densely covered with silvery 

 pile. Clypeus (if the light portion wholly coincides with it) very low and 

 broad, with a median lobe extending upwards ; it is probable, however? 

 that the sides of the clypeus above are dark. Anterior margin of clypeus 

 with three very distinct, but small, teeth. A brush of yellowish hairs in 

 front of each mandible at its base. Mandibles rufous, with alight spot 

 at base, simple. Punctuation of vertex much closer than in. taurulus. 

 Nervures and stigma piceous or black. 



Hab. — Several of both sexes, Rincon, New Mexico, July 5, visitnig 

 the fiovvers of Chilopsis salii^na, Don. (Bignoniaceit;), in the river bed. 

 One A. taurulus was taken with them.
