fairly dense punctures, becoming' crowded on sides. Elytra parallel-sided to 

 near apex ; with rows of fairly large punctures, becoming smaller towards suture 

 and posteriorly; interstices with small punctures. Length, 2 mm. ^ 



HaJ). Lord Howe Island (A. M. Lea). Type, I. 12023. 



The impressed lines towards each side of the prothorax that, in addition to 

 the marginal ones, are so conspicuous on most species of Diplocoelus, are repre- 

 sented on the present species by a submarginal one that can be seen, from certain 

 directions, near the apex only ; the transverse line near the base of the head that 

 (when not concealed by the prothorax) is also usually very distinct, is represented 

 by a shallow indistinct one ; nevertheless the species appears to be a true 

 Diplocoelus, and to be allied to D. angiisfnlus and D. apicicoUis, but it is shorter, 

 much wider, flatter, and darker, with smaller punctures, etc. Of seven specimens 

 obtained on the island only one has the prothorax no darker than the elytra. 



Family ENDOMYCHIDAE. 

 STENOTARSUS QUINARIUS sp. nov. 



Reddish-flavous, an irregular mark on prothorax, scutellum, four spots on 

 elytra and antennae (basal joints excepted) black. Rather densely clothed with 

 pale, semiupright hair. 



Head with minute punctures. Antennae rather short, club stout. Pro- 

 thorax Avidely transverse, sides rather strongly rounded, apex much narrower than 

 base and semicircularly emarginate, sublateral striae deep, dilated at base; 

 punctures small but rather sharply defined. Elytra with sides gently rounded; 

 ^\ith regular series of fairly large punctures, becoming smaller posteriorly; inter-

Hah. Queensland: Mount Tambourine (A. M. Lea). Type (unique), 

 1. n796 



Structurally close to 8. arithnieticiis and S. quinquenotatus, but with very 

 diffei-ent markings; the four spots on the elytra are larger than on the latter 

 species, the outer ones are nuicli in the same positions, but the inner ones are 

 much nearer the base ; on the prothorax the black mark covers about the basal 

 third, und has a subtriangular extension almost to the apex. 



STENOTARSUS BIMACULIPENNIS sp. nov. 



Red, three marks on prothorax, two on elytra, scutellum and part of antennae 

 black, coxae and adjacent parts more or less inf uscated. Rather densely clothed 

 with pale, semiupright hair. 



Head with minute punctures ; with two small but distinct impressions between 

 e;) es. Prothoi-ax with sides strongly rounded, apex much narrower than base and
