PSYCHE. 



I February 1895. 



The species is quite active and a good 

 jumper. The antennae on one specimen 

 had only three segments ; a very short 

 basal one and a terminal as long as the 

 other two, which had the hairs arranged 

 verticillately. This may have been a 

 young specimen though the size was 

 large and tiie color bands typical. This 

 species has the short basal ring making 

 really fine joints to the antennae. This 

 basal ring is not shown in Emerton's 

 drawing Fig. i. Our species violates 

 the generic description of Rondani 

 by having the terminal joint of the 

 antennae too long to be called subequal 

 to the second and third. Also has the 

 fourth body segment somewhat shorter 

 than the three preceding. The drawing 

 Fig. I, enlarged 30 times, was made 

 from a live specimen by Mr. J. H. 

 Emerton ; the head was modified and the 

 elater drawn by the writer. The species 

 is named E. hexfasciata on account of 

 the six conspicuous bands upon the 

 body segments. 



Entomobrya pygmaea, n. sp. 



Ground color pale yellow. Marked with 

 purple bands. Body, antennae and elater 

 clothed with long hairs. Body fusiform, 

 broadest at the metanotum and much nar- 

 rowed behind. Head oblong, a fifth longer 

 than broad, rounded behind, widest at about 

 the middle. The eye patches oblong, a third 

 longer than wide and joined by a broad band 

 that arches forward. Head not otherwise 

 marked. Antennae stout, purple. Segments 

 in the ratio of 5 : 6 : 6 : 9, nearly. Mesonotuni 

 broad, anterior edge, sides and posterior edge 

 marked with a narrow band. Tendency to a 

 median longitudinal stripe as shown by the 

 projections on the anterior and posterior 



bands. Metanotum and the first three 

 abdominal segments bordered on the ante- 

 rior margin, the color patches reaching to 

 the band along the sides. Fourth segment 

 with an interrupted longitudinal band which 

 does not reach the anterior border or band 

 along the sides. Fifth and sixth segments 

 plain. The fourth segment of the abdomen 

 nearly twice as long as the three preceding. 



Fio 



Entomobrya pygmaea. 



Legs and elater light colored. The latter 

 slender. Manubrium to mucrones and 

 dentes as 11 : 15. 



Measurements. — Total length, i.ii mm.; 

 ratio of parts, antennal joints 5:6:6:9; head 

 15:12; body segments 5:3:24:24:34:15: 

 3:2; elater 11 : 15. 



Habitat. — Upon juniper wood in the 

 yard during March and April, 1892. 

 The wood was brought from a swamp 

 in the f;rll and this species is probably 

 arboreal in habit. Orono. Mr. F. L. 

 Harvey.
