Psyche 



[February 





large, black ocular fleck. Ocular blotches present, but pale and indefinite. Tem- 

 ples protruding, narrowly but regularly rounded, with six long hairs, one of which 

 arises submarginally; also several short ones. Occiput broadly concave, with six 



long, submarginal hairs; Margin thick- 

 ened, but little colored. Entire head rather 

 pale yellow, with the exception of the 

 mandibles, an area surrounding them, and 

 the indefinite ocular blotches. Antennae 

 differing from those in M. pici Denny, the 

 third segment being larger and goblet- 

 shaped, receiving the last. (Fig. 4b). 



Thorax slightly longer and narrower 

 than head, with more, darker coloring. 

 Prothorax with rounded sides merging into 

 the flattened, almost straight, posterior 

 margin; anterior angles rounded. A series 

 of eighteen long hairs, with several short 

 ones, extends around the sides and pos- 

 terior margin. Lateral bands present, 

 their inner margin indefinite. Metathorax 

 about the same length as the prothorax, 

 but wider, trapezoidal, with indefinite 

 posterior margin. A number of short 

 marginal and submarginal spines on the 

 divergant sides, toward the acute posterior 

 angles; two long hairs on this angle and 

 a transverse series of about fourteen long 

 hairs indicating the position of the pos- 

 terior margin. Legs rather short, with

Abdomen elliptical, truncate where it 

 joins broadly with the thorax, widest at the fifth segment; pale in color, with 

 almost transparent margins. Segments of nearly equal length, with a transverse 

 row of from twenty to thirty strong hairs. Last segment rounded, but somewhat 

 triangular in shape, with about twenty hairs around the margin, the anterior 

 ones of which are quite long; on the ventral surface are two fringes of fine hairs. 



Male varying in size, the largest one being but little smaller than the female. 

 Last segment similar in shape to that of the female, but with fewer hairs and lacking 

 the ventral fringes. Genitalia prominent, consisting of a broad anterior portion and 

 long, slender lateral appendages.
