520 NOTES ON LACHNOSTERNA. 



74. L. glabricula Lee. 

 There are ten males in the Museum collection from Texas and Kansas 



(coll. C. V. B.). 



The female of this species was unknown to Dr. Horn, and I have not 

 found it in any collection examined by me. The claspers of the male 

 genitalia are quite characteristic andstrongly modified, yet symmetrical. 



75. L. fucata Horn. 

 Not in the Museum collection. I owe the chance of studying the male 



to Dr. Horn. The claspers of the male are symmetrical and quite dis- 

 tinctive. I have not been able to obtain the female. 



76. L. exorata Horn. 



Not in the Museum collection. The specimens known are from Texas, 

 and species is probably local. To Dr. Horn I owe the chance of study- 

 ing the male, which is quite characteristic iu sexual structure. The 

 claspers are symmetrical, free in front, and with a distinctive process 

 anteriorily. 



77. L. ignava Horn. 



There are 3 $ and 1 9 in the Museum collection, all from Texas (coll. 

 C. V. R.). 



The specimens were collected by Belfrage, and the range of variation 

 in size is greater than that given by Dr. Horn. Oar smallest male is 

 .56 inch, our only female .67 inch. Otherwise the specimens agree per- 

 fectly, and show no variation at all. 



The male only has been studied, for some reason which I do not now 

 remember. The male organs are characteristic from the tendency, here 

 first strongly marked, to the oblique lengthening of the apex. The 

 claspers are symmetrical, little modified, and absolutely immobile. 



L. longicornis Blanch. 

 This must be dropped from our lists. Dr. Horn has seen the type, 

 and says that it is not North American. 



78. L. quercus Knoch. 

 There are four males in the collection — North Carolina, Louisiana, 



Florida (coll. J. B. S. and Morrison). The range of the species is thus 

 somewhat extended southward. 



The species is not at all a common one, and is not often found in mis- 

 cellaneous collections. The male only has been studied. It has, like 

 the other species with which it is allied, symmetrical claspers, not united 

 anteriorly, and sufficiently modified to be distinctive. 



79. L. inepta Horn. 



Two males from North Carolina (coll. J. B. S.) are in the collection. 

 The locality is new, Dr. Horn's specimens being from Ohio. One of our 

 specimens has the ventral characters very strongly marked, and pre- 

 cisely as described ; the other is so much weaker as to scarcely differ 

 from a specimen of quercus, in which the depression is well marked. 

 The shining surface is really all the difference I am able to make out
