230 On a new Coleopterous Insect. 



Pascoe, and are therefore almost certainly Australian. The 

 species, which appears to be undescribed, I propose to call 



Syagnus tntrudens, sp. n. 



Elongatus, crassus, subparallelus, piceo-niger, parum nitidus, rugo- 



sus ; antennis tarsisque piceis. 

 Long. 7-10 mm. 



Rostrum gently arcuate, thick, with a fine median smooth 

 line and with a groove on each side above the antennal groove ; 

 the apex shining and finely punctured. Forehead rugosely 

 punctured, with a well-marked impression in the middle. 

 Tiiorax with its broadest part in front of the middle, a trifle 

 narrower at the anterior angles than at the posterior ; the 

 sides arcuate; the base exactly fitting the base of the elytra, 

 but a trifle narrower. The surface very uneven, consisting of 

 closely placed irregular obtuse tubercles, some of which are 

 shining. Tlie interspaces with very short brownish pubes- 

 cence. Elytra very convex, humped up at the suture, with 

 a slight constriction at the base, gradually widening from this 

 to the apical declivity, where they are as wide as the widest 

 part of the thorax. Apical declivity almost vertical. The 

 region of the scutellum and some irregular, rather oblique, 

 vermiculate impressions dull black. The rest of the surface 

 covered with very irregular more or less confluent tubercles, 

 which are themselves ornamented with very small shining 

 tubercles. Near the suture, just at the apical declivity, there 

 are two tubercles which are rather more prominent than the 

 others ; these and some of the others have more or less 

 brownish hair on them. There are also some of these short 

 brown hairs just within the humeral angle. At the sides 

 there are two or three rows of elongate deep fove^. 



The punctuation of the basal portion of the rostrum varies 

 very much. Some specimens have it closely and rugosely 

 punctured ; in others the punctures are separated and the 

 surface is shining. This difference is no doubt sexual. 



This species resembles S. fuhitarsis, Pascoe (Ann. & Mag. 

 Nat. Hist. xvi. 1875, p. 56), but the rostrum is less strongly 

 curved and the tubercles on the dorsal surface of the thorax 

 and elytra are much more numerous. In S. fulvitarsis the 

 dull black surface is greater than that occupied by the tubercles; 

 in S. intrudens the reverse is the case. 



The specimens vary very much in size. I am told by 

 Mr. A. M. Lea that Syayrius is injurious to ferns, especially 

 to Adiantim, in greenhouses in Sydney.
