MONOGRAPH OF THE GENUS SAPERDA 65 



them bore for at least six inches, while others scarcely go from 

 the entrance more than twice their own length. The outer ends 

 of the burrows are closely packed with borings without and soft 

 fibers within, which also fill the inner ends. The head of the 

 larvae may be either toward or away from the opening, seemingly 

 a matter of indifference. In the former case the beetle emerges 

 from the place of entrance and in the latter, from a round hole 

 at right gngles to the burrow, probably made by the beetle itself, 

 as no such hole has been detected in the many limbs Dr Hamil- 

 ton examined, containing pupae with their heads turned from 

 the opening. Pupation occurs after the middle of April. We 

 have found them transforming at Albany Ap. i6. The beetles 

 may be found in the limbs about the first of May, though but 

 few of them emerge till the latter part of the month. 



Description [pi. 6, fig. 4]. Cinnamon brown, below gray, 

 white at sides, being of the same color as cretata. Thorax 

 with lateral white band that extends on to the base of the elytra, 

 which also have two crescent-shaped, white spots at middle, 

 divided by the suture, and two smaller circular ones near the 

 apex, also divided by suture. These spots may be nearly or 

 quite obsolete, usually in the male. The antennae darker than 

 cretata. 



Distribution. This insect has been recorded from Buffalo N. Y. 

 [Zimmerman] ; Hamilton Ont. [Moffat] ; and Dr Hamilton re- 

 ports it as common in Crataegus limbs in southwestern Pennsyl- 

 vania. The types were described from Ohio; Dr Smith has 

 recorded it from Greenwood Lake and Delaware Gap N. J., 

 and it has been listed by Messrs Leng and Hamilton from Can- 

 ada, New York, New Jersey, Pennsylvania and Ohio. 



This species is not related to cretata, which it resembles 

 in color, but has more of the characters of the less specialized 

 species, as is shown by the short, rounded head and the but 

 slightly developed process on the claws, that on the first pair 

 being very rudimentary. This relationship is further empha- 

 sized by its gall-producing larva working in the same way as 

 c o n c o 1 o r .
