From its broad thorax and other characters this species 

 should be placed near FuUcri, from which it differs rad- 

 ically in color. 



Calmalli Mines. 



It is highly probable that Mr. Champion has realized 

 the extremely close relationship existing between Calos- 

 pasta, Tegrodera and Eupompha, and but few more spe- 

 cies are needed to unite the three beyond question. Re- 

 cently (Ann. N. Y. Acad., 1891, p. 175) Capt. Casey has 

 described the genus Negalius, which does not show any 

 structural differences from Calospasta, the grooved man- 

 dibles and dilated tarsi occurring in the latter genus. 



The most remarkable discovery, however, is the result 

 of the collections of Mr. D. W. Coquillett of Los Angeles. 

 During a visit to him in May, 1893, he gave me what I 

 recognized as a Calospasta. The male has the form of 

 FuUcri (which is rather that of a Tetraonyx than a Ca- 

 lospasta), but the female is from any standpoint of class- 

 ification a Meloide, apterous and with the meso - coxce 

 overlapping the metasternum. In fact, the female was 

 described by me many years ago as Megetra opaca. 



Megetra opaca, or Calospasta opaca, as it must now be 

 called, is somewhat variable. I have three series of spec- 

 imens, the first represented by six taken by Mr. Gabb 

 near Los Angeles about thirty years ago; a second series 

 of eleven from Morrison, taken about ten or twelve years 

 ago, with no special locality other than southern Califor- 

 nia; a third series from Mr. Coquillett, taken near Los 

 Angeles in 1893. The first two series are all females. 

 In the last series three are males and four females. 



The last series has the elytra coarsely punctate sca- 

 brous, the first series the elytra are less coarsely punctate 

 and less coarsely scabrous, while the Morrison series is 

 comparatively smooth. These subdivisions are not sharply 

 drawn, but describe the general aspect of each series.
