1913] Bowditch— Stanford Expedition to Brazil 129 



Antennas yellow, apex and middle fuscous joints 3 and 4 equal, thorax with a 

 deep transverse lunate depression not attaining the margins, scutel dark brown, 

 elytra semi shining, thickly punctate, the punctures arranged pretty regularly, in 

 very close rows, the four basal spots are arranged two on either side of the suture 

 and not touching it and two humeral, the middle band shows a tendency to run up 

 and down the suture to join the anterior and posterior spots. 



Superficially resembles my specimens of denticornis Jac (though 

 not the figure in Biologia) . 



Trichaltica nigripennis sp. nov. Tav^ 



* ■ 

 Elongate, very faint bronzy black, thorax reddish yellow, feet variable from black 



to more or less yellowish, elytra feebly costulate with fine punctures geminate at 

 the sides and subgeminate on the disk and single rowed behind. 



Type Ceara length 3h mm. 



The mouth and antenna; in some examples are slightly fuscous, the punctuation 

 of the thorax is coarse, even and quite thick and the sides anteriorly show a slight 

 sinuation, the pubescence of the elytra is uniform grayish arranged in lines, the bronzy 

 color shown only faintly in a strong light. 



Larger than most of the described forms (except thammi Baly) 

 and very like an undescribed form from Argentine in my collection. 



CEdionychis bakeri sp. nov. 



Testaceous, head very dark piceous, base of antennae and apex of tibiae and tarsi 

 piceous, body beneath black, each elytra with two short, straight black lines at the 

 base, one humeral sublateral, the other almost median, also two small ante apical 

 black spots placed obliquely, the outermost faint. 



Type, Manaos, Brazil (1) length 6 mm. 



About the form and size of palpalis Jac. not much dilated and rather flattened 

 and elongate. Head smoother with only a few punctures near the eye, frontal fovea? 

 deep, eyes comparatively close, the whole space between occupied by the foveae, 

 frontal carina prominent between the antenna?, which are about half the length 

 of the body, scape very dark piceous, the next two or three joints shading off to 

 testaceous, fourth joint slightly longer than the third, mouth parts almost light 

 testaceous, thorax smooth shining, sides broadly depressed, anterior angles scarcely 

 notched at the side, elytra smooth polished very minutely punctulate, the basal 

 black marks are very narrow parallel sided black lines, the outer placed on the out- 

 side edge of the humerus and parallel to the margin and extending to the median 

 third, the inner line is almost median, parallel to the suture and the shorter of the 

 two, the rear marks are at the beginning of the convexity, in line with the front 

 marks, the inner a black dot, the outer a stain, apical third of the elytra sparingly 

 ciliate. Many of the genus seem to show ciliaejon the elytra to a greater or less 

 extent though it is rarely mentioned. My specimens of palpalis .Jac show it.
