 of North American Beetles of the Family Cleridae. — Proc. U.S.

The first part of this paper deals in detail with the morphology 

 and taxonomy of the larvae of North American Cleridae ; the second 

 with the general habits and seasonal history of these beetles. 



The Cleridae are among the principal predators of wood and bark 

 boring beetles, the adults attacking the adults of the destructive 

 species, while the larvae feed upon the eggs and broods in the bark 

 and wood. Under natural conditions they are not of great importance, 

 but these conditions may be upset in their favour by properly conducted 

 control work. Their dissemination in infested regions, in addition to 

 control work, would therefore be of great value. 



The adults are very active, especially on sunny days, though some 

 are nocturnal. They consume numbers of Scolytids, and other 

 small insects, though in some genera there are instances where the 

 adults are apparently not predaceous, but feed on pollen. 



Certain species of Clerid larvae in all stages are found in the galleries 

 and mines of bark and wood borers. They feed voraciously on the 

 eggs, larvae, and sometimes the dead (?) parent adults of the host. 

 The pupal cell may be made in the earth, the bark, or in the cell of 

 the host. The time of transformation to adults varies, but is generally 

 in the spring. Some species may have more than one generation in 

 a season, especially if there are several generations of the host. Others 

 appear to pass several years in the larval stage 



Among the more important of the species noticed with details of 

 their life-history in many cases are Monoj^liylla tenninata, Cymatodera 

 bicolor, Thanasimus dubius, T. nigriventris, Enoclerus quadriguttatus, 

 E. sphegeus, E. iclineumoneus, E. quadrisignatus, Xenodosus sanguineus, 

 Phyllobaenus dislocatus, Neichnea laticoniis, Chariessa jnlosa, Galeru- 

 clerus oculatus, and OrtJwpleura damicornis. These are all destroyers 

 of bark-beetles.

The attention of tea planters is drawn to the necessity for combating 

 the caterpillars of Thosea spp., Setora nitens (and other species with 

 urticating hairs), Stauropus alternus, Belippa bohor, various Psychids, 

 Geometrids, and Andraca bipunctata. In special circumstances, 

 when the usual natural checks are not operating, serious loss may be 

 caused by them. Collection is generally sufficient to check infestation, 

 but it is essential that this be done immediately the first examples 

 are observed. 



The serious injury done to nurseries by bunch caterpillars, 

 A. bipunctata, on the east coast of Sumatra, was stopped by an 

 epidemic that entirely wiped them out. A similar epidemic has been 

 observed in the case of Thosea cervina [R.A.E., A, viii, 455,.
