caudal margin. The cerci are buff and bear Vandyke brown teeth, 

 while the supra-anal plate is parrot green. 



The paratypic specimen is faded, particularly about the body, 

 but shows a similar coloration and color pattern throughout. 



Distribution. — This insect is known only from Echo Mountain, 

 one of the western foothills of the San Gabriel Range back of Los 

 Angeles, California. 



Biological Notes. — The two specimens known were both beaten 

 from the heavy chaparral which clothes the steep slopes of Echo 

 Mountain. Long continued search and vigorous beating during 

 both days spent at the locality failed to reveal other specimens. 



Remarks. — This is the frailest as well as the most highly colored 

 species of the genus and is the only one found on the Pacific 

 slopes of the southern Californian mountains. 



Specimens Examined: 2, 2 males.

 Paratype. [A. X. S. P.] 



Insara lamellata'' new species (Figs. 21 and 2S.) 



The present species shows some affinity to /. gemmicula, but 

 unfortunately we are unable to give the chief differential charac- 

 ters, owing to the fact that this species is known only from females 

 and gemmicula only from males. This insect, though resembling 

 gemmicula in some respects, shows much more robust proportions 

 than that species, the lateral outline of the dorsum of the pronotum 

 is somewhat different, and the ventral margins of the cephalic and 

 median femora are distinctive. The ovipositor is longer, and more 

 gently and evenly arcuate than in any other species of the genus. 



Type. — 9 ; San Jose del Cabo, Lower California. (Dried al- 

 cohoUc.) [Hebard Collection.] 



Description of Type. — Size medium for the genus, form robust. Head 

 and ej^es much as in /. elegans. Pronotum with dorsal length nearly one and 

 six-tenths times the gi-eatest (caudal) dorsal width; dorsum of pronotum de- 

 planate, lateral margins of same divergent in straight lines for slightly more 

 than the cephalic fifth, then with a rounded obtuse-angulation weakly con- 

 cavo-divergent for an equal distance, the remaining portion gently divergent 

 caudad with a slight concavity apparent ; cephalic margin of dorsum of pro- 



5^ In allusion to the peculiar lamellate development of the ventral margins 

 of the cephalic and median femora.
