their scaly covering, no trace of such a bar exists. The maxillary 

 palpi are dark brown and are covered with light hairs. 



Distribution. — The known range of this species is confined to 

 Lower California. 



Remarks. — As noted under antillarum, the female, in the 

 later stages of the nymphal condition, has dentiform spines on each 

 side of the ovipositor sheath; these are situated distad along the 

 ventral margin of the upper section of the valves, and in the specimen 

 before us are five in number on each side. The adults all have a 

 distinct tympanum on the cephalic face of the cephalic tibiae, but 

 this tympanum is not present in any of the nymphs.
