Described from 4 specimens, 1 female, 3 males, reared May 7, 1870, 

 The name of the rose on wliich it occurs is nnk-nown. Dr. lliley in his 

 I^sote Book says: 



A small gall. Ixiaring a general rcscmTilaiue to a mangel-wurzel seed or large l>eet 

 seed, occnrj'iDg on rose trees, and esjieeially on the single wild rose. The galls were 

 first noticed in September. 



43. RHODITES SIMILIS, new species. 



Gall. — An irregularly rounded, brown or brownish yellow, pithy gall 

 on the smaller stems of an unkimwn wild rose. They vary greatly in 

 size and shape, from a small pea-like form to a more or less globular or 

 oblong shape, some of them being an inch or more in length. There 

 is no consistency in their shape; some are i)erfectly round or oblong or 

 of various irregnlar shai)es. 



GaUflii. — Female. In stature and color, this s])ecies is very near 7»'. 

 (lichhcerus^ Harris, but the surface of the thorax is much smoother, 

 shining", the head and lateral lobes of mesothorax are darker, almost 

 black, the median and parapsidal grooves more distinct, broader, the 

 disk of the mcsopleura smoother, veins darker, while the vein at base 

 of marginal cell is arcuate. 



The male is entirely black, except the basal antennal joints, spots on 

 vertex above base of antenna', and the legs, wiiich are red, the middle 

 and posterior coxa^. being black basally. 



It may be distinguished at once fiom the male of (lichlovvrnn by its 

 nuich larger size, broad i)ara])sidal grooves, the smooth shining spot on 

 inesopleura, and the red basal joints of the antenme.
