PSELAPHIDAE. 23 



equal size ; the exposed part of the 1st covered with very minute pallid 

 squamae, so as to seem membranous ; the 2nd, close to its base, with a small 

 indistinct semicircular impression. Lexjs moderate. Tibiae slightly arcuate 

 outwardly. 



Antennae moderately elongate ; basal joint cylindric, twice as long as 

 broad ; 2nd nearly as stout as the 1st, more than half its length, a little 

 narrowed towards the base ; 3rd only about half the bulk of 2nd ; 5th 

 sUghtly larger than the contiguous one ; 4, 6, 7, and 8 moniliform ; 9th 

 transverse, yet not as large as 10th ; 11th subovate, somewhat acuminate, 

 larger than the 9th and 10th conjointly. 



Larger and evidently more shining than 2478, Z. obscurus. The puncta- 

 tion not at all dense and distinct. 



Length, | hne ; breadth, nearly | line. 



Broken River. I am indebted to Mr. J. H. Lewis for my specimen. 



3051. Tyrogetus palpalis sp. nov. Gen., Ann. Mag. Hist., September 

 1893. 



Sanguineous, tarsi and palpi testaceous ; sparingly clothed with decum- 

 bent yellow hairs, apices of elytra thickly fringed. 



Head oviform, shorter than thorax but as broad as it is, finely and dis- 

 tantly but not distinctly punctured, with a pair of interocular foveae ; the 

 antennal tubercles are somewhat approximated in front, but there is a dis- 

 tinct channel between them, which extends as far as the front of the eves. 

 Thorax convex, rather longer than broad, widest at or just behind the 

 middle, moderately rounded there, more narrowed in front than behind 

 without definite sculpture. Elytra as wide as thorax at the base, gradually 

 expanded so as to become twice as broad at the extremity, which is abruptly 

 depressed and obviously ciliated ; on each there is a well-marked sutural 

 stria, and also a more shallow median one which becomes obsolete behind. 

 Hind-body hvoadly mavginated; basal segment large, as broad as i)iit hardly 

 as long as the elytra, it is nearly horizontal ; the following 3 are curvedlv 

 deflexed. Legs elongate, moderately slender. 



Antennae long and stout, finely pubescent ; basal 2 joints cylindrical, 

 the 2nd evidently the shorter ; 3-7 about equal, longer than bi"oad ; 8th 

 and 9th slightly shorter and broader than the preceding one ; 10th dis- 

 tinctly broader and subrotundate ; 1 1th largest, oblong-oval. 



Prosternum deeply emarginate in front. The coxae elongate, nrominent. 

 and contiguous, situated close to the basal margin. Intermediate coxae 

 slightly separated. Mesosternum with a carina between the middle and 

 front coxae, the mesial depression and the sides with yellow pubescence. 

 All the coxae about equidistant from front to rear. Intermediate trochanters 

 elongate, the others shorter and thicker. Only 5 ventral segments are 

 visible ; the basal is larger than the other 4 combined. 



When compared with T. optandiis it will be seen that the 2nd joint of the 

 maxillary palpi is more strongly dilated inwardly near the extremitv. and 

 therefore more knob-like than that of the typical species. The eyes, though 

 prominent, have less-coarse facets. 



The palpi are much longer than those of Hamotulus (Schaufuss).= Tycho- 

 lyrus (Broun), and the basal portion of each joint is much more elongate 

 and stalk-Uke. 



Length, | fine ; breadth, ^^ fine. 



Waimarino. January, 1909. My specimen, minus a leg, was taken 

 amongst decaying leaves on the ground.
