distad, very mildly obliquely truncate. All of the joints of the 

 maxillary palpi are considerably longer and more attenuate than in 

 antillarum. Eyes much as in antillarum, pronotum likewise, but 

 heavier. Tegmina absent. Subgenital plate somewhat arcuato- 

 convergent laterad, broadly truncate distad with no emargination 

 whatever. Ovipositor as in antillarum. Cerci missing. Cephalic 

 tibise with cephalic face bearing a distinct tympanum. Arma- 

 ment of limbs much as in antillarum except that the serrations 

 on the dorsal margins of the caudal metatarsi are heavier and 

 less widely spaced, and number seven on inner, ten on outer margin. 

 Caudal tibiae and metatarsi very slightly longer proportionally than 

 in antillarum. 



Allotypic c? : Lower California. [Hebard Collection.] 

 Description of Allotype. — Slightly smaller than female. Pronotum 

 larger and proportions considerably longer than in antillarum, the 

 caudal margin transverse, broadly arcuate. Tegmina much as in 

 antillarum. 



In addition to the type and allotype, the entire series of specimens 

 here examined and listed below may be considered paratypic.

Color Notes. — As all but the two adult females are dried alcoholic 

 specimens, our color notes refer to these two specimens only. In 

 ground coloration they are much like antillarum, but the dorsum of 

 the abdomen is wholly black. The scaly covering of the type is in 

 perfect condition, and shows the insect to be thickly covered with 

 scales as in antillarum, but in this case the scales are metallic-bronze 

 in color. In this specimen there is a cephalic bar of dark brown 

 which crosses the eye, but is not continued on the pronotum; in the 

 two other adult specimens, both of which have almost entirely lost
