head and mixed with setse; on the prothorax, they form four 

 wide but feeble longitudinal vittse; on the legs, tliey are dense- 

 on paits of the undersurface they are dense, but vary to green 

 and to a bluisli-white. The elytra, to the naked eye, appear to 

 have most of the derm glabrous, but really have very fine setae; 

 the markings on each consist of an irregular patch near the 

 scutellum of more or less rusty-red scales, becoming whitish or 

 bluish at the edges, and connected with a smaller patch on the 

 side; an irregular, postmedian fascia, with a short extension (on 

 the fourth interstice) from same to near the basal patch, the 

 scales whitish-green and purple, with a few rusty ones; and a 

 small pale spot on the fifth interstice midway between the post- 

 median fascia and the apex; the suture on the apical slope and 

 the side (except near base) are rather densely clothed with bluish 

 or greenish scales. 



Catasarcus spinipennis Fhs.C?), var. insignis, n.var. 



C spinipeiuiis is such a variable species, that it does not 

 appear to be desirable to describe, as more than a variety of it, 

 two specimens (from Shark's Bay) that differ from the ordinary 

 forms in being much larger (12-15 mm.), spines at summit of 

 apical slope much longer than usual (about as long as the pro- 

 thorax is wide), and with very diff"erent clothing. The prothorax 

 has, within a narrow median groove, a conspicuous stripe of pale 

 metallic-green, opalescent scales, continued to apex of elytra 

 along suture; on each elytron there are also several conspicuous 

 patches of similar scales; a small one immediately in front of 

 each of the discal tubercles, a conspicuous oblique patch behind 

 the two, and another oblique patch between the median tubercle 

 and base; at the corner of each puncture in the first six rows, 

 from base to tubercles, there are four conspicuous granules (ex- 

 cept at the green patches, where the punctures are smaller and 

 granules absent); on the pronotum there are numerous small 

 tubercles, and the eyes are more conspicuous than usual; the 

 inner side of the hind femora are armed with numerous minute 

 conical granules (but these are present also on the typical form, 

 and on several other species).
