The prothoracic margins are very feebly undulated in 

 middle, but the degree is so slight that it could be easily over- 

 looked, and the species is so obviously allied to picticornis and 

 tarsalis that it was not referred to B in the table ; from the 

 species named, however, it is readily distinguished by the hind 

 tibiae. The two specimens before me have parts of the 

 appendages somewhat paler than the general colour, but prob- 

 ably on fresh ones the contrast would be more accentuated. 

 Owing to the sculpture of the fourth segment the abdomen at 

 first appears to be composed of six segments, or seven if the 

 pygidium is included. Both specimens had parts of the 

 under-surface and appendages eaten by Anthreni when 

 received, but between the two all parts are available for 

 description. 



COLASPOIDES MIMETA, U. Sp. 



(S . Reddish-castaneous with a conspicuous coppery-green 

 gloss : appendages mostly paler, but apical and half of sub- 

 apical joints of antennae black. 



Head shallowly impressed between eyes, median line 

 lightly impressed ; with moderately dense punctures of medium 

 size, becoming smaller towards base, and small and sparse 

 on front of clypeus. Antennae long and thin, third joint very 

 little shorter than fourth. Prothorax with strongly and evenly 

 rounded sides, angles distinctly armed ; with rather large, 

 unevenly distributed punctures, sparser about middle than 

 elsewhere. Elytra as on preceding species, except that the 

 punctures are somewhat larger. Flanks of jprosternum feebly 

 wrinkled in places, and with a few scattered punctures. 

 Ahdomen with a shallow depression common to the three 

 median segments, the depression bounded on each side of third 

 with a conspicuous but short apical ridge, fourth about once 

 and one-third the length of third, narrowly depressed at apex^ 

 and with a conspicuous median carina, fifth with a small 

 median fovea. Front femora strongly dentate ; hind tibiae 

 moderately long, nowhere suddenly dilated, but lower-surface 

 somewhat sinuous ; basal joint of four front tarsi strongly- 

 inflated. Length ( d" , 9)j 6-7 mm. 



9 • Differs in being more compact, abdomen more convex,, 

 fourth segment shorter than third, and all simple, hind tibiae 

 shorter, straighter, and evenly dilated from base to apex, and 

 in the tarsi ; more conspicuously metallic, and more of antennae 

 black.
