Amphigerontia , if limited to Ps. hifasciatus, is probably a sound generic 

 division. I have purposely refrained from re-opening the question of 

 the homologies of neuration in the family.

ACULEATE HYMENOPTERA 



COLLECTED BY J. J. WALKER, ESQ., E.N., E.L.S., AT GIBRALTAR 



AND IN NORTH AFRICA. 



(Part ll—MUTILLID^, SCOLIID^, and SAPYGIDM.)

Family MUTILLID^. 



MUTILLA. 



capitata, Luc. — one $ , four ? , Gibraltar. 



distincta, Lep. — two ? , Gibraltar. 



littoralis, Petagn., var. ? — one $ , Gibraltar. This $ is smaller than ordinary 

 littoralis, and has the thorax of a dark brownish-red, but I can see no structural 

 character to distinguish it from that species. 



hottentota, Fabr., three <? , 9 abundant, Gibraltar. All the specimens belong to 

 the variety tabida, Luc. 



montana, Panz. — four $ , Gibraltar. 



rufipes, Latr. — ten ? , Gibraltar. 



subcomata, Wesm. — $ , abundant, Gibraltar. Very distinct from rujipes iu 

 the sculpture of the pygidium. 



Spinolce, Lep.— two ? , Gibraltar and Tangier. The specimen from Tangier has 

 the teeth of the petiole unusually developed. 



stridula, Rossi. — $ , a few from Gibraltar. 



var. tunensis, Fab. — three $ > Gibraltar ; one ? , Tangier. 



regalis, Fabr. — one ? , Gibraltar. 



Chiesi, Spin. — three ? , Gibraltar. 



halensis, Fabr. — one $ ?, Tangier, numerous ? , Gibraltar. The apterous $ , which 

 Mr. Walker found at Tangier, I think is probably referable to this species, no male 

 has hitherto been suggested for it, and there is a great resemblance between this and 

 the females. The following is its description : — 



Head black, shining, clothed with scattered bristly black hairs, very coarsely 

 punctured ; mandibles bidentate at the apex, more or less testaceous in the middle, 

 at the base of each antenna a small rounded tubercle ; antennae piceous, 2nd joint 

 paler than the rest ; thorax red, sti-ongly rugose, clothed with rather long bristly 

 black hairs ; posterior margin of prothorax deeply and rather narrowly emarginate, 

 but with the emargination rounded at its apex ; tegulae smooth and shining ; between 

 the meso- and metathorax there is a deep constriction, and the metathorax is widely 

 rounded posteriorly, and slightly raised ; abdomen black, clothed with black bristly 

 hairs, the 2nd segment bearing two round spots of golden hairs, placed side by side, 

 as in the ? , the 3rd and 4th segments are entirely clothed with golden hairs, the 

 extreme apex of the 7th segment testaceous j legs clothed with pale hairs, tarsi 

 piceous. Length, 5^ mm.
