colorous. In size, build and punctuation of the elytra it 

 appears to resemble Q. xanthopusy but differs from that rare 

 species in its shorter antennae, of which the sub^apical joints 

 are transverse, and narrower head. It is recorded as having 

 occurred under bark of an old beech stump. 



4. Q. {M.) hrevicornu. Thisspecies, originally described 

 in Skand. Col., i, p. 175, has red elytra sparingly and not 

 strongly punctured, the sub-apical joints of its antennae 

 strongly tiansverse, the sides of its thorax without punctures, 

 a sub-globose head, with very prominent temples, which are 

 not punctulated (the fi-ontal setae, as in Q. li^evigatus, being 

 approximated to the neck, almost in the same transvei-se 

 line as the seta of the temporal angle, and the anterior seti- 

 gerous puncture being situated under the eyes exactly in the 

 genal line), and the posterior tarsi thick and shortish. 



It appears to occur under bark. 



The insect recorded in Mr. Crotch's " Catalogue " under 

 this name is apparently to be referred to the following 

 species. 



5. Q. (31.) puncticollis. This insect is shining deep 

 black, with bright red elytra, black antennae and legs, and 

 pitchy-red tarsi. No sizes are given by Thomson for any of 

 these new species, but I believe this one to be the smallest of 

 them. It is allied to hrevicorniSy from which it is stated to 

 differ in having the fi'ontal setigerous puncture situated far 

 in front of the seta of the temporal angle, and both the genal 

 punctures placed above the elevated line, instead of directly 

 in it. The punctures of the head, in fact, appear to be 

 placed exactly as in the larger Q. 4-punctatus. In the 

 build of its head and the strongly transverse joints of its 

 antennae it is stated to resemble Q. cruentm, and to differ 

 from that species in having its head and thorax vaguely and 

 very obsoletely punctuied at the base, its elytra sparingly
