each side; fourth with a band, hidden by the overlapping third segment ; 

 fifth with a broad band. Apex with a fringe of dark hairs. Venter 

 ferruginous, immaculate. 



Hab. — Mesilla Valley, New Mexico, about a mile south-east of the 

 Agricultural College, on Gutierrezia $arot]ircB, var. viicrocephala. Octo- 

 ber 5, 1895. 



Apparently nearest to N. zebrata, Cress., but differs by the 

 immaculate venter, etc. Mr. E. Saunders remarks (in litt.) that in the 

 European Nomadte the first joint of the flagellum is generally extremely 

 short, often scarcely visible. This seems not to be usual with our species. 

 Chyphotes mirabilis., n. sp. — $. Length, about 11 mm.; head 

 rounded, about as big as anterior part of thorax ; eyes hemispherical or 

 bean-shaped. Antennae gradually tapering to a very fine point, scape 

 stouter than flagellum, funicle hardly apparent. First joint of flagellum 

 half length of second. Mandibles with a small tooth within. Maxillary 

 palpi 5-jointed ; labial palpi apparently 3-jointed. Thorax narrow, 

 deeply constricted in middle, hind portion longest. Intermediate tibiae 

 with two spurs. Tarsal joints tipped with whorls of spines. Abdomen 

 shaped much as in Photopsis, first segment rounded, its suture with the 

 second deeply constricted, its base rapidly attenuate to a narrow petiole. 

 Surface of abdomen with close shallow punctures, becoming subcan- 

 cellate. Colour dullish chestnut-red, tips of antennae darkened, tarsal 

 spines black, tibial spurs dull white. The head and the anterior portion 

 of the thorax are densely covered with appressed pale golden pubescence, 

 on dorsum completely hiding the surface. Intermingled with this are a 

 few erect black hairs. Remaining parts of the body visible, some sparse 

 pale pubescence on sides of hind part of thorax, on legs, and sides of 

 abdomen ; hind coxae with a small patch of dense pale pubescence, hind 

 margin of first abdominal segment broadly but irregularly covered with 

 silvery hairs, hind margin of second segment with a pair of silvery hair 

 patches, overlapping third ; and the same, less developed, on hind margin 

 of third. In addition to the above, there are everywhere sparse erect 

 black hairs, which are more abundant at the sides of the abdomen 

 towards the tip.

 College, July, 1896. 



I have given generic as well as specific characters in the description, 

 as this remarkable insect may form the type of a new genus, or at least z, 

 subgenus.
