on a new species of piieij.opsis. 219 



Phellopsis suberea. 



Elongata, parallela, opaca, squamosa ; thorace postice con- 

 tricto ; elytris posticis 6-tuberculatis. L. 19-21 mill. 



Head: broadly and roughly marginate in front, the margin 

 being divided into three parts by an elevation on each side over 

 the basal joint of the antennae; the central area is occupied more 

 or less with small black tubercles, or little boss-like elevations. 

 Thorax : has two rather acuminate tubercles over the neck, and 

 the medial portion behind the tubercles has irregular ridges and 

 depressions ; the sides anteriorly are rather elevated and distinctly 

 dilated, with the angles a little produced and obtuse ; from the 

 middle of the lateral ridge the thorax is posteriorly narrowed, 

 and the basal line is the width of the bases of the elytra, on 

 which it encroaches somewhat, especially before the region of the 

 scutellum. Scutellum is small. Elytra : on each side of the 

 suture before the tubercles are two rows of large ill-defined 

 elongate punctures, with somewhat raised interstices ; between 

 the tubercles and the apex of the elytron the suture is margined 

 with a row of black tubercles, which resemble those on the 

 thorax. Before the apex of each elytron are two well-defined 

 tubercles, which are transversely placed and touch each other at 

 their base. The innermost tubercle is connected with the base of 

 the elytron by an elevated ridge (often more defined in some 

 specimens than in others), and parallel to this ridge is a shorter 

 ridge, which is abbreviated before and behind. Between the two 

 tubercles described and the apex of the elytron is a third con- 

 spicuous tubercle. The whole of the upper surface of the body 

 is more or less clothed with small brownish scales (elongate 

 under the microscope), many of which are lost by abrasion during 

 the active life of the insect. The antennee are moniliform, the 

 9th and 10th joints being slightly compressed and trigonate, and 

 the llth, as stated above, free. In general form and sculpture 

 this species very much resembles others, especially Phellopsis 

 ohcordata, Leconte, and Nosoderma veimstuni, Champion, and 

 some allowance must be made in reading this description, as the 

 superficial structure varies a little in different individuals. 



This species is perhaps diurnal in the early summer, as I first 

 found it actively crawling on old trees which had been split by 

 electricity at Chiuzenji, lat. '>05°, on the 10th June, 1880 ; but in
