Tregellas. Fromthe Mathews Collection(no. 4908) via the Rothschild Collection.  COMMENTS: Mathews cited his catalog number of the holotypein the original description. He cataloged three Tregellas specimens at the same time, but I consider only one of the other two specimensa paratype: AMNH 659404(Mathews no. 4909), male, collected 9 May 1908at Olinda. A second paratypeis AMNH 659427(Mathews no. 2726), an unsexed specimen collected in Gippsland, Victoria, on 17 July 1886, and received from Ashby.   AMNH 659424, male juvenile, collected  28 December 1908at Sassafrasby Tregellasmay also be a paratype; its data do not match the data in Mathews’catalog for the third specimen and I did not find it elsewhere in his catalog, but Mathewsfrequently did not catalog juvenile specimens. Thethird specimen, opposite catalog no. 4910, is listed as a male collected on  20 December 1908and the locality ‘‘ Olinda’’ is dittoed from the other two specimens. Probably, a specimen with data matching this entry was once in Mathews’collection and was exchanged to persons unknown; if found, it is a paratypeof tregellasi. AMNH 659406and 659407 (no. 11689, only one entry), collected on  6 October 1910on Mt. Dandenongwere collected before he described tregellasibut not cataloged by Mathewsuntil  November 1912, long after the description was published. Thefollowing four specimenswere not found entered in Mathews’catalog and are not considered paratypes: AMNH 659408, an undated specimen collected in the Dandenong Rangeby Chandler;  AMNH 659423, male, collected  24 November 1911at Lorneby J. Ross;  AMNH 659425and AMNH 659426, collected at Lang Lang, but undated. 1907-05-11 USBGN Thomas H. Tregellas. From & Mathews Collection & Rothschild Collection.
