ABT. 2 BEETLE LARVAE OF GALEKUCINAE BOVING 29 



MesotJwrax and irietathor(£x. — ^Without distinct sclerites; setae 

 minute and club shaped. 



First to eighth ahdoTninal seffments (fig. 9). — Without distinct 

 sclerites ; setae dorsally few, minute, and club shaped ; laterally with 

 a single moderately long, pointed seta in epileurum. 



Ninth abdominal segment (fig. 8). — With a rather small, miter 

 shaped in outline, slightly chitinized pygidial shield carrying mod- 

 erately long, pointed marginal setae. 



Tenth ahdominal segmerd. — In common with the other galerucine 

 larvae developed as a strong pygopod. 



Leg (fig. 9). — With the paronychial appendix only about half as 

 long as the claw. 



Habits. — Found mining inside of the leaves of Chenopodium album 

 and a perennial Atriplex species, at King City, Calif, (according to 

 unpublished notes made in 1918 by C. F. Stahl, of the Division of 

 Truck Crop Insect Investigations, Bureau of Entomology, United 

 States Department of Agriculture) and also in Grindelia (according 

 to Essig: Insects of Western North America). No injury to sugar 

 beets known from the larvae, though the imagines seriously injure 

 the tops of the beets. No records as to where the larvae pupate. 



Taxonomic co^nments. — The larva of Monoxia consputa is essen- 

 tially different not only from the larva of Monoxia puncticollis but 

 from other larvae of the subfamily Galerucinae, to which, however, 

 it unquestionably belongs. It represents a separate generic type of 

 the Galerucinae and is distinguished by a series of characters peculiar 

 to many mining larvae, particularly of the subfamily Halticinae, 

 namely, a strongly built frons, extraordinarily long posterior pro- 

 longations of epicranium, the absence from the typical body segments 

 of distinct sclerites with well-developed setae, and unusually short 

 paronychial appendices.
