AN AMERICAN SPECIES OF TEMPLETONIA. 



By F. L. Harvey, Orono, Maine. 



Templetonia americana n. sp. 



Mr. Macgillivray, in his recent catalogue of the Thysanourons 

 of North America (Can. Ent. December, 1891), makes no men- 

 tion of the occurrence of Templetonia in America. Having 

 studied a species of this genus the first season that is quite com- 

 mon about Orono, Me., we record the following. observations 

 upon it : 



Generic cfiaracters in every particular as recorded by Lubbock (Mono- 

 graph Collembola and Thysanoura p. 142). 



Specific characters.— SWwery white, sometimes pale brownish or rusty 

 color, laid on in spots and streaks; a delicate pink reflection, especially 

 from young specimens; clothed with silvery iridescent scales; eye patches 

 very small, pale brown. Head nearly round, somewhat pointed in front, 

 broadest behind and somewhat longer than broad. Antennae white, five 

 jointed, basal joint short, about one-fourth the length of the second; 

 terminal joint nearly or quite as long as the third and fourth together, 

 slender, and, in mature specimens, composed of seventeen sub-joints, the 

 basal and terminal sub-joints each one-fifth the total length of the joint; 

 the middle three-fifths composed of fifteen nearly equal sub-joints; in 

 younger specimens the terminal joint seems shorter and composed of 

 fewer sub-joints. Body elliptical and rounded anteriorly, widest at the 

 fifth segment; first, fifth and sixth segments long, third segment short. 

 Legs white, rather long; larger claw long and slender; elater long, basal 

 joint four-fifths the total length. Thoracic collar of numerous bowed, 

 •club-shaped hairs; similar ones on the head, and a dense tuft of hairs 

 projecting forward between the antennae and reaching to the third joint; 

 scattered long hairs on the segments of the body. 



Measurements. — Total length 1.65.; head, .345 mm. long, .292 mm. 

 broad; antennae, .718 mm.; length of the joints in the ratio of 1-4-5-6-11; 

 elater, .8 mm.; basal joint, .367 mm.; claw, .046 mm. long; segments of 

 the body in the ratio of 15-10-6-10-15-13-7-3 in one specimen, and in 

 another 11-6-2-6-8-15-5-2. 



The above measurements were made from the largest specimens seen. 



Remarks. — This is a smaller species than T. crystallina Muller. 

 The largest ones we saw did not measure over 1.65 mm., while 

 the majority were never over 1.5 mm., and many less. Lubbock 

 gives the length of T. crystillina Muller as two and a quarter 

 millimetres. Our specimens are not obovate, but more elliptical 

 oblong, and widest at the fifth segment. The antennae of Lub- 

 bock's species as figured in his monograph, are considerable more
