498 SOUTH AMERICAN HALTICIDAE (cOLEOPTERA) 



basal portion and on each elevated knob is placed a sharp, backward curved 

 spine. The transverse depression forms a broad flattened area on the disk 

 which is covered with fulvous pubescence and forms the bulk of the band 

 above described. At the rear of the band where the elytral declivity begins 

 is a group of four or five spines on each side. There is a secondary depression 

 just before the apex which is marked behind by two more spines. The entire 

 surface is dented with fine punctures and in the depressions is the short yellow 

 pubescence. Body beneath shining black, legs black with the coxae and tarsi 

 dark rufous, the rufous apex of the hind femora is clothed with fulvous pubes- 

 cence. Claws appendiculate. Should apparently be placed near braccatus 

 Clark. 



Simulates in appearance some of the small longicorns. 

 One example. 



Panchirestus (?) prasinus nov. sp. 



Ovate, stout, above light olive green, labrum, body below and 

 legs yellow, joints six, seven and eight of antennae and the anterior 

 tibiae and tarsi more or less darkened. 



Type.- — Cachabe, Ecuador; low c, I, 1897, (Rosenberg). 

 Length 4.5 mm. 



Clypeus swollen, smooth shining, front longitudinally foveate and with 

 fairly plain, smooth frontal tubercles forming the upper edge of the swollen 

 clypeus, vertex and neck closely, strongly lounctate; antennae filiform, reach- 

 ing about one-third the length of the elytra, joints nine, ten and eleven lighter; 

 thorax transverse, margined, strongly angulate a little before the middle, 

 anterior angles also prominent surface thickly punctate, strongly obliquely 

 depressed on either side, a faint antemedian callous; elytra rather convex, 

 strongly punctate striate, covered with very fine pubescence and also with 

 rows of sparse long hair, no trace of any basal depression, hind tibia with two 

 spurs, claws cleft. 



I place this form in Panchrestus on account of its palpi and 

 shape of the thorax which seems near that of rufescens Clk. 

 Unfortunately I have only one mutilated example of the genus 

 in my collection and that is one from the second Jac. collection 

 marked "n.i.m.," determined by me as rubicundus Clark. 



One example. 



Loxoprosopus jacobyi nov. sp. 



Elongate, head, thorax and legs dirty yellow, labrinn dark, 

 antennae dark, joints eight to ten flavous, elytra dirty testaceous 

 brown with sutural edge and a faint sub-marginal line of ashy 

 pubescence, the ground color of the line being sometimes partly 

 flavous.
