serpentinus and state that ventralis is a synonym. The National 

 Collection contains 27 specimens as follows: a topotype of ven- 

 t rails from Enterprise Fla. June 14; eight examples from Lake 

 Worth, Fla. (Soltau Coll.) ; Ten examples from Cocoanut Grove 

 (labelled Biscayne Bay) Fla. Apr. 30, May 10 (Hubbard and 

 Schwarz) ; two from Miami, Fla. (Wickham) ; one from St. Lucie, 

 Fla. Apr. 20 (Hubbard and Schwarz); one from St. Catherine 

 Isl., Ga. April 19 (Hubbard and Schwarz) and one from Savannah, 

 Ga. (G. Noble larvae in fruit of Per sea catesbyiana) 1 besides 

 three examples from Cayamas, Cuba, Mar. 2, 3, and May 22 

 (Schwarz). These latter are so like the others that I believe 

 the LeConte name must remain a synonym although a comparison 

 of the aedeagus of a Lake Worth and a Cayamas specimen show 

 some slight differences in outline of apex, the Cuban form being 

 slightly more deflexed and rounded than the Florida example 

 which is slightly truncate apically. The forms treated as ser- 

 pentinus by Champion 1904 probably belong 'partly to this species 

 and partly to the species above described as persiae but no male 

 specimen before me has the hind tibia of the shape indicated in 

 his figure 19b. To the above distribution should probably be 

 added his record from Jamaica. 



Other Insects. 



Another weevil (Rhyncolus lauri] from seeds of avocado from 

 Mexico, was described about eighty years ago by Gyllenhal, 

 but no one seems to have been able to indentify this species. 

 Champion 1909 states that the type could not then be found in 

 the Stockholm Museum but that the species probably does not 

 belong in Rhyncolus. Except for the pale elytra more than three 

 times as long as the prothorax the original description might 

 apply to what we are now calling Caulophilus latinasus Say, 

 which Boheman redescribed from material sent by, say, only 

 nine pages ahead of Gyllenhal's description of Iduri. C. latinasus 

 seems to be native in our Southern States and Champion 1909 

 adds Mexico, Guatemala and Madeira to the known distribution 

 but the specimens I have seen vary considerably and may not all 

 be latinasus. Injury to avocado seeds by this species has been 

 mentioned by Schwarz 1912, Sasscer 1915, Blatchley and Leng 

 1916, Pierce 1917, Popenoe 1918, Hoyt 1918, and by Popenoe 

 1919. 



The small Scolytid from a Panama avocado seed mentioned by 

 Schwarz 1912 has not yet been described but Dr. Hopkins be- 

 lieves it represents a new genus related to Spermatoplex. The 

 Scolytid mentioned by Sasscer 1915 and by Hoyt 1918 seems to 



1 This plant is now listed in Ocotea but is presumbly a misdetermination of 



Pcrsea borbonia.
