Otherwise this might be regarded as a second species. The beak is sul- 

 cate like Otiorhyjichus sulcatiis, but twice the length, and the scape of the 

 antennae scarcely reaches the eye. The elytral ornamentation of sukatus 

 is less noticeable and more pubescent like, and none of the tubercles of 

 the thorax and elytra, which are much smaller, are perforate, those of the 

 intervals being arranged in irregular clusters. 



Conotrachelus tiaso Lee. I am not aware of a record of this species 

 occurring in the Northern States. Last year and also the present I bred 

 it from the fruit oicratcegus — haws — as well as C. posticatiis. The species 

 are very close and are best separated by the two yellowish white spots on 

 the thorax of naso. C. cratcegi is, however, the great haw worm next to 

 the larvae of the Lepidopterous Grapholitha prunivora Mels., which 

 developes with, but a couple of weeks later, than the beetles. 



DESCRIPTION OF THE LARVA OF DATANA MAJOR G. & R. 



BY HARRISON G. DYAR, RHINEBECK, N. Y. 



Young larva. — Body dark reddish, inclining to black ; otherwise as 

 in the following stage. 



Before last moult. — Body black or reddish black, with eight longitu- 

 dinal clear white stripes, as broad as the intervening spaces or broader, 

 with the exception of the dorsal space. Beneath are three partly obsolete 

 white lines, two of them interrupted by the legs. The head and cervical 

 shield all dark mahogany red, as are also the abdominal feet, the bases 

 of the thoracic feet and two spots on segments 4, 5, 10 and 1 1. Thoracic 

 feet black. The anal plates are black or dark mahogany red ; sparsely 

 distributed white hairs. Length about 30 m.m. 



Mature larva.— Body black ; stripes broken into a series of irregular- 

 ly square or rectangular white spots. In the three upper rows on each 

 side these spots occur two on each segment situated near the edges of 

 the sef^ment. The lower row consists of a spot before the spiracle, 

 alternating with an elongated one overlapping on two segments, so that 

 these spots nearly alternate with those of the upper rows. Head, cervical 

 shield, anal plates, all feet (except thoracic) with their bases and two spots 

 on segments 4, 5, 10 and 11, dark mahogany red. Below are a few white 

 dots representing the usual stripes. Scattered whitish hairs. Length 

 about 60 m.m.
