 ■ Sci., Ill, 1^2?,. 198; ibid. II, 126. 

 Oval, convex, glabrous. Black, strongly shining; elytra with spots as 

 mentioned in key. Thorax with a bisinuate row of coarse punctures near 

 the base. Elytra with a row of similar punctures on inner half of base 

 and two to four short rows before the middle and nearer the suture than 

 the sides. Length 3.8^.5 mm. 



Frequent throughout the State. February 23- November 8. 



*942a (2975c). Scaphidium quadrigttttatdm piceum 



Melsh.. Proc. Phil. Acad. Nat. Sci., 



II, 1844, 103. 



A color variety of guadriguttatum which is wholly 



shining black above. It is found associated with that 



species and in winter is even more frequent, being found 



especially beneath the bark of old, fungus-covered beech 



logs. (Fig. 174.) 



Throughout the State. January 24r-Deceiiiber 25.

942b (2975a). Scaphidium quadeiguttatum ohliteeatum Lee, Proc. Phil. 

 Acad. Nat. Sci., I860, 322. 

 The absence of coarse punctures on the disk of elytra and the small 

 size of the elytral spots are the only characters given by LeConte and Casey 

 to distinguish this form from qiiadrignttntvm. 



In my collection are several specimens taken in Vigo County, 

 which have the elytra whoUy devoid of discal punctures and yet, 

 like piceum, are entirely black. I have not seen the spotted form 

 from the State, but the type of LeConte came from near Evansville, 

 Indiana. In all probability Horn was right in regarding both 

 piceum and oMiferatum, as varieties, * Casey to the contrary not- 

 withstanding.* * 



Cypariiivi- flai'ipcs Lee, chestnut-brown, legs and antennae paler, 

 length 3.5 mm., is a southern form- which Dury records from Cin- 

 cinnati.
