SCAPTES. 223 
tibie with the outer apical angle broadly produced. Scaptes appears to me to be 
best placed in the “ Trachyscelides,” though agreeing in some of its characters with the 
‘* Hopatrides ;” it would seem to approach the North-American genus Ammodonus, Muls. 
(a genus known to me from description only), in many of its characters. 
1. Scaptes squamulatus. (Tab. X. figg. 6; 6a, labium; 60, maxilla and 
maxillary palpus.) : 
Broad oval, moderately convex, the entire upper surface (when denuded of scales) dull black and closely and 
somewhat irregularly punctured, densely clothed with light grey or brownish scales (often more or less 
variegated with lighter patches or spots) and scattered short decumbent club-like hairs; prothorax rounded 
at the sides, the sides converging anteriorly from the middle, the anterior angles broad and very prominent 
though obtuse, the posterior angles subrectangular, the lateral margins finely denticulate, the entire base 
fringed with short golden-brown hairs; scutellum shining; elytra closely and regularly punctured (more 
regularly and closely than the prothorax), without traces of strie, with numerous rows of very short, 
decumbent hairs, and (in clean fresh examples) with about three or four interrupted rows of light grey 
and brownish spots (the light and dark spots being placed alternately in the same row); beneath dark 
reddish-brown or piceous, slightly shining, coarsely and rather closely muricately punctured, each 
puncture bearing a short cinerous or golden decumbent hair. 
Length 44-6 millim. 
Hab. Mexico, Presidio (Forrer), Vera Cruz (Sallé); Nicaracua (Sallé), Chontales 
(Belt); Panama, Tolé (Champion).—Cotomsia (coll. F. Bates); Amazons, Santarem 
(H. W. Bates). 
The numerous specimens before me from the above localities appear to me to 
represent one rather variable species; some examples have the rows of light and dark 
spots much more clearly indicated, one of which, from Chontales, is figured ; Amazonian 
specimens agree well with others from Central America. 
I met with this species not uncommonly at Tolé, beneath stones on the open savannas 
of the low country. 
Group BOLITOPHAGIDES. 
‘This group is represented in our country by a few species, all but one of which 
appear to be undescribed ; not a single species has hitherto been recorded from Central 
America. ‘These species are contained in three genera, one of which is described as 
new. In Calymmus and Ozolais the third and fourth ventral segments have not the 
usual distinct coriaceous hind margin. 
The different species are found beneath bark or in fungoid growths on trees. 
Eutomus, Lac. (= Rhipidandrus, Lec.), represented by one or two species in Mexico 
and Guatemala, was formerly included in this group by Leconte and Horn; more 
recently, however (cf. Class. Col. N. A. p. 232), these authors have included it in the 
Cioide; Lacordaire placed it in the Scolytidee ; Eutomus may be known from the 
“ Bolitophagides ” by the four-jointed tarsi and the structure of the antennz.
