HYMENOPTERA FROM LOWER CALIFORNIA. 93 



MUTILLID^. 



Sph^rophthalma Sackenii Cress. San Jose del 

 Cabo, October. Three 5 specimens. 



Sph^ropthalinia magna Cress. San Jose del Cabo, 

 October ; west side of El Taste, September ; Mesa Verde, 

 October. Eighteen specimens, sixteen of which are 

 from the first mentioned locality, which seems to denote 

 that the species is more abundant in the warmer part of 

 the peninsula and that its true home is in the tropics. In 

 distribution this species ranges into California and Ne- 

 vada. The specimens before me show great variation in 

 size, 13—25 mm. 



Sph^rophthalma gloriosa Sauss. San Jose del 

 Cabo and Mesa Verde, October. Numerous specimens. 



SpHyErophthalma ferruginea Sm. A specimen 

 from San Jose del Cabo, October, I feel obliged to refer 

 to this species, although in Smith's decription there is no 

 mention made of the pale golden pubescence on second 

 abdominal segment ; otherwise the specimen tits the de- 

 scription well. 



Sph^rophthalma zapoteca B1, One specimen. San 

 Jose del Cabo, October. 



SPHyEROPHTHALMA ERECTA n. sp. 



5. — Ferrugineus; clothed with sparse, long, erect, 

 black hair; mandibles at tip, tibia? and tarsi, and apical 

 margin of first and second abdominal segments slightly, 

 blackish; pubescence of cheeks and abdomen beneath, 

 pale; in certain lights there is seen an appressed, silvery 

 pubescence on the dorsal segments of abdomen; on the 

 basal portion of the second dorsal abdominal segment 

 there are two longitudinally parallel, elongate, yellowish 

 marks, and on the apical portion there are two similarly 

 colored, semiovate spots. Head very large, much wider
