one which seems to be Trichodectes limbatus, Gervais, or T. climax, var. 

 major, Piaget. The uame applied by Gervais is accepted, for the differ- 

 ences between the two appear to be specific and not varietal. 



Description. — The characters of Trichodectes climax are : Head wider 

 than long, quadrangular, presenting a wide but shallow indentation in 

 front, at which the two antennal bands stop ; antennae hairy, a little 

 longer with the male than the female ; the first joint is larger and 

 shorter than the others ; the second longer than the third ; the abdomen 

 b,ears median spots, the width of which diminish as their length in- 

 creases. The last segment of the male carries two hairy cushions. 

 Head and thorax, reddish-brown ; abdomen, pale yellow; spots, brown- 

 maroon; bands, blackened. Length, female, 1.6™™ ; male, 1.3™™. (Neu- 

 mann.) 



The female of this species is broader and the male a little shorter than 

 in the corresponding sexes of T. sphwrocepTialus. The dorsal sutures of 

 the head are much darker and plainer ; the edge of the head and ad- 

 domen are margined by a pronounced dark band. The differences 

 between the anterior and posterior feet are much more decided. The 

 dark bands of the back of the abdomen of the male seem to offer the best 

 characteristics, viz : They gradually increase in length to the fourth, 

 when they begin to narrow. Beginning next the thorax the first band 

 is narrow ; the second, third, and fourth are wider; the succeeding are 

 narrower ; posterior to the line of hairs on the second to the fifth seg- 

 ments are extra narrow bands, which are about equal in width. The 

 egg of this species is shorter and narrower.
