MISCELLANEOUS NOTES AND NEW SPECIES 375 



ante-ocular process; mandibles evenly bowed externally, the dorsal 

 process high, slender, basal and obliquely pointed; labrum transverse 

 and feebly bisinuate at apex; frontal margin transverse, with two small 

 sinuses at each side, the frontal tubercles distinct, the central small but 

 strong, at the junction of three feeble ridges; prothorax impunctate, 

 with well marked apical angles and lateral depression; elytra oval, 

 apparently rather narrower than the prothorax, the striae more evident 

 suturad, the flanks more shining, pubescent throughout, the lateral 

 striae more impressed and distinctly punctate; middle tibiae usually 

 with two, the posterior with one, external spinule. Length 51.0 mm.; 

 width of head 15.0, prothorax 18.5 and elytra 18.8 mm.; length of pro- 

 thorax 14.0, of the elytra 27.0 mm. Guatemala (Chiquimutilla). 



Until the excellent figure of opacipennis given by Kaup was 

 examined, I had considered this species to be identical, but it 

 differs in the narrower and more elongate elytra, sharper ante- 

 ocular processes and less spinose external tibial margins, as well as 

 in many other features. From beckeri Zang, it differs in its much 

 smaller size, narrower form and in the pubescence of the elytra. 



The distinction made by Kuwert between Paxillus leachi and 

 minor, relating to the presence or absence of a humeral tuft of 

 conspicuous stiff hairs, is a good one; this tuft does not exist in 

 parvus Csy., which is therefore a valid species and not a synonym 

 of leachi as stated by Arrow. 



A number of interesting species of Trichius Fabr., have been 

 accumulating in our collections for some years, principally inhabiting 

 the southern Atlantic regions; it would seem well to make these 

 known briefly as follows: 



Trichius rufobrunneus n. sp. Moderately stout and of pale and rich 

 red-brown color, with the legs more obscure, the head piceous-black; 

 pubescence very short; clypeus transverse, feebly sinuate medially at 

 apex; prothorax nearly as long as wide, rounded at base, the sides broadly 

 angulate before the middle, the punctures small, close-set; elytra two- 

 fifths wider than the prothorax, shorter than wide, inflated near basal 

 third; intervals two and four depressed and finely, densely punctate, the 

 convex intervals sparsely; flanks shining and sparsely punctate in basal 

 third, opaque and darker brown in apical two-thirds, the two short 

 transverse white lines distinct; pygidium with very short fine sparse 

 pubescence, with white incrustation rather narrowly at the sides; legs 

 slender. Length (d 71 9 ) 9.8-12.0 mm.; width 5.0-6.0 mm. Florida 

 (Marion Co.). Twelve examples. 



Distinguishable readily from piger by the coloration and the 

 nearly bald pygidium.
