angles. So the noted " dog's head " breaks out now and then in both 

 the species named. 



I think, therefore, that the genus Megonostoma should be dropped 

 from circulation, for there certainly is no more to justify a separate genus 

 for these two species than there is for Edusa or for Behrii. 



NOTES ON SOLPUGID^. 



AY W. G. WRIGHT, SAN BERNARDINO, GAL. 



My first So/puga was found under a clod of hard earth, which I over- . 

 turned in search of spiders. Upon being uncovered, it reared its palpi 

 aloft with a menacing motion, and backing down as closely as possible 

 into a little depression, stood motionless' till captured-. This was in 

 August, 1882. The specimen is apparently a $, Datrines constrida, of 

 medium size. The head and mandibles conform closely to the figure of 

 that species, but it differs materially from the letter-press description of 

 Constrida ; as to the other parts. 



The second individual was taken in the evening, after a favorable op- 

 portunity for observing its motions. It was in May, 1883, at 9 or 10 

 o'clock, as I was sitting at my work-table writing a letter. A shaded lamp 

 threw a strong light down upon pen and paper. For a few moments I 

 had sat still, elaborating a sentence in my mind, when a magnificent 

 Datrines came \\\) from under my left arm as the elbow was extended 

 after usual fashion, and ran with rapidity across the paper upon which I 

 was writing, to the cover of some loose papers two feet to the right. As 

 it ran I distinctly saw its motions. The body was nearly or quite drag- 

 ging, and its palpi were raised up and curved forwards, and were in rapid 

 motion, evidently as antennae or feelers, and not from fear or as a menace. 

 Immediately recognizing my visitor, I hastily got the alcohol bottle and 

 soon dislodged the animal from the papers, when it ran, with the same 

 motions as previously, to regain its old hiding-place under the table, almost 

 re-passing over its previous track \ and as it dropped over the edge of the 

 table, by good fortune it fell into the bottle. 



This, larger one, is evidently a Datrines^ but is unlike any plate or 

 description seen by me. It is much larger than D. constrida, but, like it, 

 is also a ^ .
