504 Mr. D. Sharp's descriptions of new genera 



Bryaxis euplectodes, n. sp. Castanea, angustula ; capite 

 piano, tuberculis frontalibus nullis ; protliorace simplice, 

 brevi ; eljtris stria suturali, striaque discoidali, basi pro- 

 fimde impressa sed apicem baud attingente ; abdomine 

 segmento basali elongate. Long. corp. (ultra) 1 mm. 



Mas, abdomine segmento ventrali basali fossa profunda, 

 fundo subtiliter striata, apice carina elevata transversa 

 terminata, per totam longitudinem impresso. 



Antenna? rather longer than head and thorax; 1st and 

 2nd joints abovit equal in length and thickness; joints 3 — 9 

 slender; 5th joint slightly longer than the contiguous 

 ones ; 10th joint short and transverse, twice as broad as 

 the yth ; 11th joint large, broader than the 10th joint, 

 and three or four times as long as it. Head with the 

 ujoper surface quite flat and free from impressions, the 

 summit of the vertex slightly depressed in the middle. 

 Thorax broad and short, but a good deal narrower than 

 the elytra, a good deal narrowed behind, with a slight 

 longitudinal impression in the middle in front of the base. 

 Elytra more than one and a half times as long as the 

 thorax ; the after-body narrow and parallel. The legs 

 rather long and moderately stout. 



A very remarkable species, with great resemblance in 

 form to Trimium and EujAectus. 



I have but a single specimen captured by Du Boulay 

 in West Australia. 



Dalma, nov. gen. 



Corpus sat elongatum, subdepressum. Palpi max- 

 illares breves, articulo 2° basi gracile, apice abrupte fortiter 

 incrassato, articulo 3° parvo subtriangulare, articulo ultimo 

 crasso, securiforme-ovali, longitudine articuli 2'. Caput 

 mediocre, nullo modo rostrato-deflexum, tuberculis fron- 

 talibus evidentis, sat distantibus. Antennae breviuscida3, 

 apice fortiter clavatte, 11 -articulate, basi distantes. Pro- 

 thorax cordatus. Prosternum magnum ; coxas anteriores 

 robusta3 modice exserta). Trochanteres intermedii breves, 

 ut femoris apex cum coxa articula est. Coxte posteriores 

 prominentes basi fere contigue. Abdomen sat elongatum, 

 minus deflexum, marginatum, segmentis ventralibus sex, 

 quorum primo vix conspicuo. Pedes robusti modice elon- 

 gati, tarsis unguiculo unico valido. 



This is a genus of considerable interest, for it indicates, 

 in a clear manner, that the position assigned by Leconte
