Coptocycla clavata Fabr. Clubbed Tortoise-beetle. 



This leaf-beetle was taken in the south ravine of the .Bates woods 

 (Sta. IV, b) by T. L. Hankinson June 28, 1911 (No. 7678). It 

 is known to injure the potato, tomato, eggplant, and bittersweet. 

 The larvae and adults feed upon the same kinds of plants (Lintner, 

 Sixth Rep. Injurious and other Ins. N. Y., pp. 126-127. 1890). 



Tenebrionid^e 



Bolctothcrus bifurcus Fabr. Horned Fungus-beetle. (PI. LIX, figs. 

 1, 2, and 3.) 



This curious-looking beetle was found on the shelf-fungus Polyp- 

 orus in the lowland forest (Sta. IV, c) Aug. 26 (No. 173). 



I have found this species very abundant near Bloomington, 111., 

 where at times it was difficult to find an example of Polyporus which 

 was not thoroughly honeycombed by the larvae of these beetles. A 

 single shelf has been found to contain several beetles. They were 

 generally discovered within galleries excavated within the fungus. 

 On July 1 1 in such a shelf I found larvae and pupae in abundance. 

 Other dates of capture are June 3 and July 6. Riley and Howard (In- 

 sect Life, Vol. 3, p. 335. 1891) also report it from Polyporus. Fig- 

 ures of the larva and pupa are given by Packard ('83, p. 474) and 

 descriptions by Gissler (On coleopterous larvae of the family Tene- 

 brionidcc, Bull. Brooklyn Ent. Soc, Vol. 1, pp. 85-88. 1878). 



Meracantha contractu, Beauv. 



Larvae of this beetle were taken under dry leaves in the upland 

 forest (Sta. IV, a) Aug. 17 (No. 83) ; and others from under damp 

 leaves at the base of the wooded slopes of a ravine leading to the low- 

 land forest (Sta. IV, b) Aug. 22 (No. 140). The latter larvae were 

 associated with the ant Stigmatomma pallipes. These larvae are 

 often confused with wireworms (Blatcridae). 



I found the beetles occasionally in the forest at Bloomington, 111., 

 June 1 3 ; and Aug. 1 on the papaw. 



I have a specimen of this larva, in very rotten wood, showing 

 the sinuous larval boring (PI. XXX), from the Brownfield woods, 

 Urbana, 111. (March 9; collector, D. M. Brumfiel). Wickham has 

 described and figured the larva (Journ. N. Y. Ent. Soc, Vol. 4, pp. 

 119-121. 1896). 



PyROCHROID/E 



Pyrochroa sp. 



A single specimen of a larva belonging to the above family was 

 taken August 22 (No. 130) in the ravine (Sta. IV, b) from under
