parently are lost, but those of L. pinetorum were in an individual 

 vial and clearly labeled. The sample consists of 12 nearly legless 

 syntypes, seven males and five females, and is number 2175; according 

 to the label it was collected by Harger alone, whereas the published 

 account states that it was collected by him and Professor Collier. 



All the millipeds are listed in the continental checklist 

 (Chamberlin and Hoffman 1958), and detailed accounts of those Harger 

 assigned to Trichopetalum have recently appeared (Palmen 1952; 

 Shear 1971, 1982; Shelley 1988, In Press). 



In the following accounts I update these reports by providing 

 information on the type specimens, a brief historical review of each 

 species, and pertinent anatomical observations. Complete synonymies 

 are presented, and each species is placed in its proper order and 

 family.

Type Specimens — Five male and nine female syntypes (nos. 

 2208-2209) collected by O. Harger in May 1872 at New Haven, 

 New Haven County, Connecticut; one male and one female syntype 

 (no. 2125) taken by an unknown collector on an unknown date at 

 Mt. Carmel, ca. 7 mi (11.2 km) north of New Haven, New Haven 

 County. 



Remarks — Harger assigned three new species to his genus 

 Trichopetalum but did not specify the type species, so Cook and 

 Collins (1895) subsequently designated T lunatum. It is the only one 

 of Harger's five milliped species to retain its original combination. 

 The identity of T lunatum has been well established by Cook and 

 Collins (1895), Palmen (1952), Causey (1967), and Shear (1972); a 

 male syntype from New Haven that I dissected conformed to these
