June, 1917] ScHAEFFER: NoRTH AMERICAN ClERID.E. 131 



CIcriis jontcli Leng was named after our mutual friend Louis H. 

 Joutel and I regret very much to be compelled to relegate it to 

 synonomy. 



Clems viduus was described from North America and was listed 

 in Crotch's list but omitted in the Henshaw list. The species seems to 

 be very rare and besides the type of jonteli, which was collected by 

 Mr. Leng in Georgia, I have seen a specimen in Col. Robinson's col- 

 lection taken by him in Virginia. The species has received three 

 additional names from Spinola, Chevrolat and Gorham. 



Clerus rosmarus var. virginiensis new variety. 



Form, size and coloration as in rosmarus, except that the entire elytra 

 is reddish, the lunate transverve fascia is bordered on each side with black, 

 the upper and lower black border uniting at suture ; the subapical black 

 fascia of typical rosmarus indicated in var. rufuhis by darker reddish color 

 than the red apex and clothed sparsely with short black hairs, apex clothed 

 with sparse white hairs. Abdomen red, femora piceous, except the front 

 femora which are reddish, tibiae and tarsi black. Length 6.5 mm. 



Virginia. 



I have seen a number of specimens of rosmarus from different 

 localities but not one that would seem to be intermediate between 

 typical rosmarus and var. rufulus. In Clerus lunatus similarly 

 colored specimens occur with only a narrow black border limiting 

 the lunate fascia which, however, are connected by intermediate 

 specimens with a form from Texas which has the elytra entirely 

 black from a little above the lunate fascia to apex. 



Clerus thoracicus var. subcostatus new variety. 



Form, size and coloration as in C. thoracicus but elytra dark blue, rather 

 more coarsely sculptured and alternate intervals with more or less irregu- 

 larly elevated longitudinal lines and clothed with short, dark hairs. Length 

 6 mm. 



Enterprise, Florida (O. Dietz). 



I have another specimen from New Braunfels, Tex., which agrees 

 with the Florida specimen in the characters given above. 



In typical Clerus thoracicus the elytra may be black or dark 

 blue but is less coarsely sculptured than in the form described above 

 and without the irregularly interrupted longitudinal costse, the 

 pubescence of elytra when viewing the specimens from the front
