A NEW ENTOMOBRYA 

 By J. W. FOLSOM 



Entomobrya wheeleri sp. nov. 

 (Fig. 18) 



Head and body mottled with blue pigment, with no definite 

 color pattern (Fig. 18a). Sternum white. Antenna; blue; first 

 three segments darker apically. Coxae slightly pigmented, also 

 femora distally and tibiotarsi proximally. Furcula unpig- 

 mented. Eyes 8-8, on black patches, the two inner proximal 

 eyes of each side being smaller than the others. Antennae one 

 and three-fifths times as long as the head, with segments in 

 relative lengths about as 9:22:19:30; basal ring large, resem- 

 bling a segment. Mesonotum not projecting anteriorly. Fourth 

 abdominal segment almost five times as long as the third. 

 Unguis (Fig. 185) with a pair of lateral teeth and with two 

 inner teeth, the proximal tooth being doubled. Unguiculu.s 

 three-fifths as long as the unguis. Furcula attaining the ventral 

 tube. Manubrium and dentes subequal in length. Dentes 

 crenulate dorsally. Mucrones (Fig. 18c) subequally bidentate, 

 the basal spine being absent; two fringed seta; projecting from 

 each dens extend almost to the end of each mucro. Corpus of 

 tenaculum with a single curving ventral seta. General clothing 

 of dense short setae. Clavate, ringed setae occur on the anterior 

 part of the head, on the last abdominal segment, and on the dor- 

 sal region of the manubrium. Pointed, fringed setae are present 

 on the last two abdominal segments and on the furcula dorsally 

 and ventrally. A few long, stout, fringed setae occur on the 

 antennae, two or three on each coxa, a few on femur and 

 tibiotarsus, and several on the anterior surface of the ventral 

 tube. Length 1 mm. 



The preceding description applies only to the largest speci- 

 men as regards proportions and pigmentation, for these 

 characters vary according to the age of the individual, as usuai. 

 Thus in a specimen 0.39 mm. in length, there is scarcely any 

 blue pigment, the fourth antennal segment being, however,
