112 Mr. P. Cameron on some 



Omalaspis, as we have seen, is Britlsli, being repre- 

 sented by biusta. I have examined the specimen men- 

 tioned by Mr. Marshall (/. c.\ but it unfortunately is not 

 in good condition. It is black ; the six basal joints of the 

 antennae and the legs are bright red ; the basal three- 

 fourths of the abdomen at the sides, and the basal half at 

 the sides and above, dull red. The tegulas appear to be 

 dull red. The thorax is opaque, the mesonotum is faintly 

 punctured. Length a little over 1 line. 



Om. niger, Htg., differs from it in having the whole of 

 the antennae red, and the coxre and base of femora black, 

 while there is no red on the abdomen. Om. noricus, Gir,, 

 has the first joint of the antenna3 black and the rest red ; 

 the abdomen is entirely black, as are also the tegulaa ; the 

 antennfe are stated to be as long as the head and thorax, 

 while in biusta they are longer, being as long as the head, 

 thorax and half of abdomen. 



Biusta appears to be covered with a faint pale pu- 

 bescence on the thorax, it being especially long on the 

 metathorax. 



I am glad to be able to record Onychia, Keinh. {Cal- 

 laspidia, Dbra., Gir.), as British, and what adds to the 

 interest of the discovery is that our species appears to be 

 undescribed. I Avould propose to call it — 



Onychia nigripes, sp. n. 



AntennaB as long as the body, filiform, the apical joints 

 a very little thicker than the basal ; the 1st joint is nearly 

 double the length of the 2nd ; the 3rd is the longest, 

 being a little longer than the 4th, which is itself somewhat 

 longer than the 5th ; the rest become shorter and thicker 

 to the last, and also more globular and more truncated at 

 the apex; the 13th joint is longer than the preceding two, 

 being nearly as long as the 3rd ; the colour is black for 

 the greater part, the basal half of the joints of the flagelhmi 

 being pale testaceous, this colour being esi3ecially notice- 

 able on the apical joints. Head black, roughly punctured. 

 Thorax black, opaque, roughly punctured ; the prothorax 

 is marked with longitudinal striations. The mesonotum 

 is deeply fringed with long white hairs. Abdomen black, 

 smooth, shining ; the little ring on the petiole is piceous. 

 Legs black ; the anterior knees, base of all the tibire and 

 tarsi testaceous. Wings hyaline, tinged with testaceous 

 near the nervures.
