wliole insect is clotlied with long erect hairs. The prothorax 

 is quite twice as wide as long, and is about three-quarters the 

 width of the elytra behind the middle, where they are widest. 



The female scarcely differs from the male in size, colour, or 

 markings ; the legs, however, are a little more uniformly 

 piceous. The antennae scarcely differ from those of female 

 L. nodicornis except in the basal two joints being clear 

 testaceous. 



Two specimens on the flowers of a species of Acacia near 

 Port Lincoln. 



N.B. — It is to be noted that in the above descriptions the 

 -second joint of the antennae in the male is supposed to be 

 viewed from directly above its flattened upper surface. From 

 other points of view its appearance is quite different.

LTCTUS. 



L. {Xylotrogus) Irunneus^ Steph. In Mr. Masters' catalogue 

 {Proc. Linn. 8oc., N.S.W.) this species, probably by a clerical 

 error, is entered as "i. hmnneus, J. AV. Douglas," followed by 

 a reference to the Ent. M. Mag., 1S76. In the article referred 

 to, however, Mr. Douglas merely records the fact of his having 

 found L. hrunneiis in England under the bark of some logs of 

 wood that had been imported from AVestern Australia. The 

 species was described by Stephens long ago in the " Illustra- 

 tions of British Entomology," and appears to be cosmopolitan. 

 I have met with it myself in the Hawaiian Islands (vide Trans. 

 Boy. Dublin Soc, 1885), and it has been recorded from many 

 other localities. M. Lacordaire (in the Gen. des Coleopteres) 

 rejects Mr. Stephens' genus Xylotrogus as a frivolous sub- 

 division of Lyctus, saying that it has no other distinctive 

 character than the absence of a deep longitudinal fovea on the 

 thorax. I have not Stephens' description to refer to, but 

 whether it notices the following characters or not the species 

 on which the genus is founded differs from typical Lyctus in 

 the very evident separation of the anterior coxae ; so that 

 either M. Lacordaire's "hanches anterieures contigues" in his 

 diagnosis of Lyctus requires to be amended or Mr. Stephens' 

 genus must stand. I prefer the former alternative, as it ap- 

 pears to me that the degree of contiguity of the anterior coxae 

 is not of generic importance in insects of the Lyctus type. 



L. costatus, sp. nov. Subopacus ; elongatus ; piceus ; pro- 



thoracis latitudine majori antice posita ; elytris perobscure 



lineatim punctulatis ; interstitiis 4°, 6°, et 8° evidenter 



elevatis ; coxis anterioribus hand contiguis. Long. 2f 1. 



This species is clothed with short pubescence, less sparingly
