126 THE CANADIAN ENTOMOLOGIST. 



tuberculoid granules, much larger on the thorax ; the intervals are slightly 

 alternately narrower, sometimes on the same plane, sometimes the 

 narrower deeply depressed, producing a costate appearance ; the serial 

 punctures are large and unevenly spaced ; the apices are conjointly 

 rounded with a slight notch. This species is fully as large as gemellus. 

 The examples seen are from Vancouver Island and the high mountains 

 of British Columbia. 



Mr. Casey has described some forms which have not been seen. 



L. OREGONUS, the describer states, differs from palustris (geminatus) 

 in the more elongate form, much smaller and less transverse prothorax, 

 longer and almost non-carinate beak, coarser serial punctures, and more 

 prominent sutural angles of the elytra. Habitat — Oregon. 



L. PiNGUis, Casey, is said to differ from geminatus by its more obese 

 form, stouter beak and coarser punctuation, more exposed humeri, more 

 declivous elytra and denser vestiture. Habitat — Colorado (Rocky 

 Mountains). 



L. ERRANS, Casey, is described from a unique taken in the mountains 

 of New Mexico, near Abiquire, in which the elytral intervals are separated 

 rather by striae than by series of punctures, alternately narrower and 

 depressed, the narrower more finely sculptured and clothed with denser 

 brown squamules ; the elytra tessellated with patches of denser pale 

 scales, and the usual median spot not distinguishable. The beak is 

 longer than the thorax, with a broad and feeble carina. 



L. CANADENSIS, Cascy. — As stated under capucitius, this species 

 should probably go into synonymy, but the form has not been seen and 

 there may be some really specific structure not mentioned by the de- 

 scriber. The length is given at .44 inch, and the habitat, Canada (North- 

 west). 



L. GEMELLUS, Kirby. — This species is only mentioned to complete 

 the genus ; it is not nearly related to any of the others ; more elongate, 

 elytra longer with four or five broad elevated interspaces separated by 

 striae-like impressions, each interspace with a depressed linear furrow, 

 roughly scalerous, lines of denser white scales on the intervals simulating 

 vittae ; thoracic stripes and abdominal spots white, median elytral spot 

 absent ; mesosternum as in perforatus, the femoral sinuosity a little more 

 abrupt. Length .40-.50 inch. Habitat — Vancouver Island to Hudson 

 Bay.
