128 THE CANADIAN ENTOMOLOGIST. 



Liburnia albolineosa, Fowler. Twelve specimen?, all of which 

 are paler than those from Florida, the West Indies and Mexico, but 

 apparently not distinct. 



Liburnia circumcincta. Van Duzee, M.S. Three examples. This 

 species is described in a report on Florida Hemiptera, now in press. 



Liburnia ornata, Stal. One brachypterous female. 



Agallia sanguinolenta. Provancher. One example. 



Athysanus exitiosus, Uhler. Common here as in Florida and 

 Jamaica. 



Thamnotettix perpunctala. Van Duzee. Several taken on the 

 fine shore grasses. 



Tinobregmus vittatus. Van Duzee. Two males, one female 

 and two larva?. The male has more recently been described by Prof. 

 Osbom. On the mainland it has been taken only in Fljiida and along 

 the gulf coast. 



Jassus olitorius, Say. Common. These were of the typical dark 

 variety found throughout the northern States. 



SOME NEW BEES, AND OTHER NOTES. 



BY T. D. A. COCKERELL, BOULDER, COLO. 



Melissodes dagosa, n. sp. 

 <$ . Length, 10 mm; black, with the clypeus bright lemon-yellow; 

 the labrum (except at extreme sides) and a small spot on the mandibles 

 also yellow ; hair of head and thorax abundant, silky-white, without any 

 black ; eyes pale greenish ; antennae reaching to metathorax, scape black, 

 flagellum black above, but broadly pale reddish-orange beneath ; wings 

 clear, nervures and stigma ferruginous ; legs black, with light hair ; small 

 joints of tarsi red ; hair on inner side of hind basitarsus orange ; abdomen 

 with pale hair ; hind margin of first segment broadly hyaline ; hind mar- 

 gins of segments 2 to 6 with broad, conspicuous white hair-bands ; sixth 

 and seventh segments toothed laterally, the teeth short ; hind margins of 

 ventral segments reddish-subhyaline. In my table of Melissodes (Trans. 

 Amer. Ent. Soc, 1906), this runs to M. lupina and M. agilis, which it 

 greatly resembles, but from which it differs in the very much shorter 

 antenna?. The middle joints of the flagellum are little more than half as 

 * long as they are in those species. The antenna? are also wholly without 

 crenulation.
