Insect Notes from L^aguna Beach, 

 California

The following notes were made during the Summer Session 

 at the Pomona College Marine Laboratory, Laguna Beach and 

 vicinity during June and July, 1921. 



ORTHOPTERA^ 



Two earwigs, Anisolabis aniiidipci^ Lucas and A. maritima 

 Brun., were commonly taken in the canyons in damp places under 

 stones, logs and in wet leaves. The former occured under stones 

 close to the creeks. 



The cockroach, Arenivaga (HomoUxjamia) erratica (Rehn), 

 was taken under a large stone. The specimen taken was appar- 

 ently full grown and a wingless male. A winged female was also 

 collected. 



The ra?L\\i\ds,Stagmoynayitis califoruicn R & H and Litaneidria 

 obscura Scudd., were both taken on the hills near the ocean beach 

 during July 1921. 



The common tree cricket in the Laguna Beach region proves 

 to be Oecanthus nigricornis var. argentinus Sauss. A number of 

 these were taken during July. 



The red Jerusalem cricket, Stenopelmattis fuscus Hald., was 

 taken in a rotten log in Niguel Canyon. The common species at 

 Laguna Beach which regularly traverses the streets at night and 

 may often be found in the morning, is S. longispina Brunner 

 (Syn. S. irregularis Scudd.). 



The large blue-winged grasshopper, Leprus glaucipennis 

 Scudd., proved to be a match for the most active entomologists and 

 eluded many a net. The species measures from 2 to 214 inches 

 long and the color matches perfectly the color of the soil on the 

 hills, back from the ocean where it occurs. The blue under-wings 

 easily characterizes it. 



ITHYSANOPTERA 

 Western grass thrips, FrcoikUnieUa (Euthrips) occidentalis 

 (Pergande)". A pale yellowish-brown species was abundant in 

 the heads of Junciis xiphiodes Meyer growing in fresh water at the 

 mouths of the canyons near the ocean.
