i^Apothimis ShdiTT^ (^))* 



Form comparatively short and broad, depressed, the eyes 

 large, the disk of the vertex narrowed on the frontal margin; 

 the antennal joints from the sixth upward gradually wider; 

 prothorax much wider than the head, widest before the middle, 

 and sinuate toward the base, the lateral margin crenate; 

 elytral disk broad, nearly quadrate; abdomen broad, margin 

 broadly retuse, the fourth segment not prolonged; the pres- 

 ternum is carinate. 



T. CAViFRONS, Lee. Color uniform reddish-brown or 

 darker, legs, antennae, and palpi, paler. Pubescence pale, 

 abundant. Length 0.8 mm. Plate XL, Fig. 104. 



Head small, broader than long, eyes large, coarsely facetted, 

 behind the middle, therefore, the tempora are short, nearly 

 transverse; occiput convex, not impressed, and, in aline behind 

 the eyes, twice as wide as the frontal margin ; vertex abruptly 

 elevated above the eyes, with two small pubescent foveae in a 

 line through the middle of the eyes, connected by a broadly 

 impressed sulcus, parallel to the lateral margin of the disk, 

 shallow near the fovea and very deep behind the frontal mar- 

 gin; the surface between the foveee has an impressed puncture 

 in the center. Supra-antennal tumefactions strong, externally 

 angulated, the frontal connecting ridge fine and sharp; clypeus 

 and labrum prominent, the latter very broad, with the anterior 

 margin straight, and narrowed at its base. Antennae as long 

 as the head and prothorax together, first and second joints 

 sub-cylindrical, equal in width; third to fifth gradually smaller, 

 obconical; sixth to ninth sub-equal in length, rapidly increas- 

 ing in width; the ninth two and one-half times wider than 

 long; tenth nearly as long as the two preqeding together and 

 twice as wide as long; the last, large, ovate, truncate at its 

 base, as long as the three preceding joints together. The last 

 palpal joint is rather long, of the same form as the last anten- 

 nal joint. Prothorax widest just before the middle where it is
