apart and arranged in two rows of six or eight spines each, and armed 

 above for nearly their entire length with two rows of close set, short, 

 stout spines. 



General color light wood- brown. The top of the head is generally 

 marked longitudinally with obscure stripes and the pronotum is orna- 

 mented abov^e by faint clepsydrate markings and with a chestnut 

 brown stripe down the middle and, in the female, extending along the 

 back to the tip of the abdomen. The posterior femora arc marked 

 longitudinally on the outer face with a black line and the tip is black, 

 as is also the base of the corresponding tibine. This femoral colora- 

 tion is present in both sexes and will probably prove more constant 

 than the body coloration. The ovipositor is infuscated apically. 



Meamtreinents. — Length, pronotum, male, T mm., female, T; elytra, 

 male, 1.5; posterior femora, male, 18, female, 18.5; ovipositor, 12.5; 

 width, pronotum at posterior margin, male, 5, female, 5.

Specimens examined. — One adult female (fig. 51), the type, from 

 San Diego, California (Orcutt), and an immature male from Indio, 

 California, June 5 ((!audell). Through the courtesy of Prof. F. H. 

 Snow I have been enabled to study an adult male from Bill William's 

 Fork, Arizona (Snow). 



The above-mentioned adult male agrees with the female type except 

 as pointed out in the above description. It may eventuall}^ prove 

 wrong!}' associated, in which case it will represent a new species, for 

 it is certainly not conspecific with any of the three following forms. 

 The immature male f r(mi Indio was taken under loose bark of a spiny 

 tree standing alone in the desert. The cerci of this young specimen 

 are proportioned about like those of the adult, l)ut the inner tooth is 

 scarcely indicated. The anterior tibia> are armed above with a single 

 preapical spine on the outer margin like that of the female. 



The insect figured by Woodworth in Bulletin No. 112 of the Cali- 

 fornia P^xperiment Station as A. notatus is either not this species or 

 an unusually poor figure, the pronotum being figured with lateral 

 carinas, which is certainly not true of the insect now under discussion. 



ATELOPLUS MINOR, new species.

 Related structurally 

 to the preceding spe- 

 cies, but difi^'ers in the 

 following parti culars : 

 The ovipositor is not 

 so decidedly curved
