MISCELLANEOUS VISITORS. 



The majority of the miscellaneous insects visiting this plant 

 were present for its nectar although some were predatory. 



The Hemiptera shoukl probably be included among the in- 

 jurious insects, but no definite records of feeding were obtained 

 against those not already mentioned. An Aleyrodes in the winged 

 form was occasionally seen. Mr. Heidemann has determined the 

 following species taken in Stone Cabin Canyon: Lygccus bi color 

 H. S., L. lateralis Dall, Dendrocoris arizonensis Barber, Corizn* 

 punctatus Signoret, Notocyrtus sp. and Creontiades rubrinerri* 

 Stal. From Thurberia in Pima Canyon we obtained Lopidea 

 confluens Say and an Empoasca. A 7-elns renardii Stal was col- 

 lected in Ventana Canyon. 



One small brown female Mantis, Litaneutria obscura Scudder, 

 and two species of grasshoppers, Barytettix neomexicana Scudder, 

 and a Schistocerca found only in nymphal stages, were taken in 

 Stone Cabin Canyon, and the Barytettix was also on the plant in 

 the Santa Catalina Mountains. These insects were determined 

 by Mr. Caudel). 



The following beetles determined by Mr. Schwarz were collected 

 on Thurberia at Fish Creek, Scymnus ardelio Horn, two species 

 of Attains, one of them new, Petalium bistriatum Say and Lcn/n 

 balteata Le Conte. In Stone Cabin Canyon we took Scymnus 

 ardelio Horn, Hippodamia convergens Guerin, Thalassa montezuum 

 Mulsant, Cryptorhopalum pumilum Casey, Chauliognathus .pro- 

 fundus Le Conte, and C. obscurus Schseffer, E-noderux abruptus 

 Le Conte, a species of Hydnocera, Hymenorus rotundicoUis Casey, 

 and Epitragus fusiformis Casey. This last mentioned species and 

 the Chauliognathus profundus were very common on many plants. 



Three species of Bruchus were found at the nectar in Stone 

 Cabin Canyon, Briichis impiger Horn, B. amicus Horn and B. chiri-
