This species is closely allied to C '. laticollis, Horv., but is 

 distinguished from it by the much broader vertex. Dr. 

 Horvath, who has kindly compared specimens of nidicola with 

 the type of laticollis in the Budapest Museum, writes to me 

 that laticollis differs from the new species also in the following 

 characters : — The upper side is still more finely and densely 

 punctulate, the lateral margins of the pronotum are more 

 distinctly reflexed, the orange-yellow basal border of the pro- 

 notum is strongly dilated exteriorly and thereby the humeral 

 angles are very broadly yellow, this colour being narrowly 

 extended even along the lateral margins through three-fourths 

 their length ; and the legs are brownish, with only the coxae, 

 trochanters (except their black tip), and tarsi yellow. There 

 are also some minor differences in the mutual length of the 

 antennal joints. Horvath also writes that the female specimen 

 standing in the Vienna Museum under the name laticollis may 

 possibly, upon closer examination, prove to belong to nidicola. 



The colour of the larvae of C . nidicola is fuscous-black, 

 but the abdomen is red, with the two or three last dorsal 

 segments in the middle greenish-testaceous in hue ; only in 

 the youngest larvae the abdomen is, at least sometimes, en- 

 tirely black. In the oldest larvae the apical flaps of the 

 hemelytral parts of the scuto-tegmen are testaceous. The 

 antennae are brownish-testaceous, with the last joint (except 

 a narrow basal ring) much paler. The legs are of a livid 

 testaceous colour. The head is considerably longer than 

 broad with much smaller eyes than in the imago and with 

 no trace of ocelli even in the full-grown larvae ; in the youngest 

 larvae the eyes scarcely project beyond the postocular margins 

 of the head, and the distance between the eyes is eight times 

 broader than an eye. Rostrum notably longer than in the 

 imago, reaching or slightly passing the middle of the venter. 

 Antennae constructed almost as in the imago, but in the 

 youngest larvae with the second joint comparatively shorter, 

 being scarcely longer than the last joint. The larvae before 

 me belonging to the younger stages are in so poor condition 

 that their other structural characters cannot be properly made 

 out, but the two last stages show the following additional 

 characters : — 



Fourth Stage. — Distance beween eyes six times broader 

 than an eye. Pronotum three times broader than long in the 

 middle, lateral margins narrowly reflexed, the transverse im- 

 pression placed far behind the middle, anterior lobe more 

 than three times longer than posterior lobe, with an impressed 

 longitudinal median line not quite reaching the apical margin, 

 and with a foveate impression on each side of the disk. 

 Scutellum coalescent with the tegmina, but separated from
