200 THE CANADIAN ENTOMOLOGIST 



Opinions that rhodopus is a distinct species, the differences pointed out by 

 Schwarze holding good without variation throughout the series. 



Lebia collaris. Dej. A single specimen was beaten from a bunch of 

 Spanish moss in high, dry upland oak woods on April 20. It is 5.2 mm. in 

 length, and agrees in every particular with Dejean's original description in 

 which the length is given as 21/2 lines, and breadth a^s V/4 lines. The eyes are 

 very prominent, as stated by him, the side margins of the thorax very broad, 

 recurved and of nearly equal width throughout, while the oiiter joints of the 

 antennae are very dark brown. Attention is called to these points simply for 

 comparison with examples of the following species which I had had in my col- 

 lection for several years under the name of collaris, their determination having 

 been made from Horn's "Revision of the Species of Lebia"? without access 

 to Dejean's descriptions. 



Lebia nigripennis Dej. Horn in his "Revision" makes this a synonym 

 of L. collaris. From the text I judge that he did this without seeing Dejean's 

 type of either species, as he says: Both Dejean's and Chaudoir's descriptions 

 "do not seem to indicate any difference between nigripennis and collaris except 

 in size and the colour of the head and thorax? These characters are ordinarily 

 good, but in the present instance the colour of the head and thorax is seen to 

 vary in our series." He then gives the length of collaris (including nigripennis) 

 as 5 mm., whereas Dejean gives the dimensions of nigripennis as length P^ 

 lines, breadth ^4 line, or 3.5 and 1.2 mm. 



In the four specimens at hand, three from Dunedin and one from Sanford, 

 Fla., the size is exactly as given by Dejean for nigripennis; the eyes are dis- 

 tinctly less prominent than in the collaris specimen above mentioned; the side 

 margins of thorax are less wide and very evidently narrower toward the front 

 angles; and the outer joints of antennae are pale reddish-brown in all. Leaving 

 aside the colour of the head, which is variable, these characters are, in my 

 opinion, sufficient, when taken in connection with the much smaller size, to 

 restore the name of nigripennis, as I believe that these small specimens represent 

 the species which Dejean had before him in naming that form. In no one 

 species of Lebia does the size vary as much as between these two forms, and 

 Dr. Horn apparently ignored this dilTerence in size when he combined the two 

 and placed the length at 5 mm. The L. colhris, of Horn, is said by Leng to occur 

 in the Middle and Southern States, and has been recorded from several stations 

 in Florida. 



Lebia fuscata Dej. This species is sometimes attracted by light, two 

 specimens having been taken at porch light on March 15. 



Aphelogenia vittata Fab. One example, April 19. This seems to be a 

 rare beetle not only in Indiana but also in Florida. It is not mentioned by 

 Schwarz, and is recorded only from Jacksonville and Lakeland by Leng.s All 

 of my specimens from both States were taken by sweeping vegetation in low, 

 damp localities.
