are more uniform in color, and show less of a tendency to a band; the 

 veins are more distinctly lined and the outer angle is less rounded and 

 retreating. The submarginal line on the fore wings is less rounded in 

 at the costa, and on the hind wings is much nearer the outer margin.

 much more developed in cinctaria, and the insect is more than twice as

Note on Quadrina diazoma, Grote. 



By John B. Smith. 



In Mr. Grote 's catalogue of 1882, Quadrina diazoma is placed 

 in the ' ' Hemileucinr and is associated with Hemileuca, Hyperchiria and 

 Coloradia, which are all typical Bombycids. The genus and species had 

 been a great puzzle to me, and being unrepresented in N. Y. collections I 

 wrote Prof. Snow, for information. On a recent visit to Washington, 

 Prof, b-'now kindly brought me the unique type which is in poor condi- 

 tion. I saw at a glance thatthe insect was wrongly placed in the catalogue, 

 and very little study decided me in placing it with iht Cossidae, with 

 strong tendencies in appearance to Hepialus-d. tendency which the vena- 

 tion of the primaries emphasizes, while the secondaries are Cossid. 

 Primaries with 12 veins, the ist or only internal being sinuate. 

 The cell is very short, and the median vein gives rise to 2 near its incep- 

 tion; to 3 at about its middle, and to 4 and 5 close together at the tip: 6 

 and 7 are on a stalk from the end of the subcostal vein: 8 arises near the 

 tip, 9 and 10 are on a stalk about one third from tip, and vein 10 runs 

 to the apex: V. 1 1 runs from the middle of the sub-costal to the costa 

 about one-fifth from tip. The cell is closed by an angulated vein at tip. 

 On the secondaries there are two internal veins. The cell is shurter than 

 in the primaries and is closed in the same way; 2 arises from the 

 middle of cell, 3, 4 and 5 close together at the tips: 6 is straight from 

 the upper angle of cell and a direct continuation of the sub-costal: 

 7 arises from the sub-costal close to base and is connected near its incep- 

 tion by a cross vein with the costal vein, which is sinuate and has a short 

 spur at base. Essentially this is also the venation of Gloveria. 

 There appears to be no frenelum. The tongue is obsolete and the 

 palpi are short. The antennse are moderately long the joints very 

 short, lengthily bipectinated. There appear to be no ocelli. The 

 legs are moderately long, the median and hind tibiae each with a pair of 

 short terminal spurs. The anterior tibiae have the epiphyses reduced to 

 a small tubercle in a shallow depression. The tarsi are strongly spined 

 and the claws are simple. In color the insect is a dull, even luteous red 

 with traces of an outer broken black band. Altogether this is a remark- 

 able insect, and the genus is probably a good one, nearly related to 

 Gloveria but belonging to the Cossidcs.
