Variations. — As might be expected in a species with such rough 

 sculpture, the distinctness of the costse may vary and the sculpture 

 between them be less pronounced. The coloi- also varies, but this is 

 a matter of greater or less maturity. 



With this species I have united ventricom Lee. The two species 

 Avere each described from two females, the cribrosa types being smaller 

 and less mature. The genus Eugastra was founded to receive these 

 species, but there are no reasons why it should be retained distinct 

 from Lachnosterna. 



Occurs in Texas in the Rio Grande Valley. 



I have a species from Mexico closely allied to the above, but 

 smaller ; the elytra shorter and broader, with but four costse. As it 

 is represented by a female in not very good state, and as it is not 

 advisable to complicate bibliography I pass it with this mention. 



3. Li. Sfqiisilis Lee. — Ovate, convex, piceous-black, shining; surface with 

 sparsely placed, white, scale-like hairs. Body 9 with rudimentary wings. 

 Clypeus entire concave, mai-gin reflexed ; surface coarsely, not densely punc- 

 tured. Thorax widest at middle, the margin serrate, sides arcuate, disc deeply 

 coarsely punctured. Elytra deeply uol closely punctate, the discal costs? entirely 

 obliterated. Pygidiuni convex, strongly punctured. Metasternum with moder- 

 ately dense short hair. Length .80 inch ; 20 mm. 



The above short description is practically a transcript of that of 

 Dr. LeConte. The si)ecimen is not now before me, and as far as I 

 know the unique has never been duplicated. By its facies it recalls 

 ventricosa if the latter is dei)rived of costse. 



Collected at El Paso, Texas. 



4. Li. lareta Lee. — Ovate, convex, facies robust, rufocastaneous, dark brown 

 or piceous, moderately shining. Body feebly winged in both sexes. Clypeus 

 feebly sinuate, border reflexed, more widely in front; surface coarsely and mod- 

 erately closely punctate, the front more coarsely. Thorax broadest at middle, 

 very little narrowed i!i front, margin distantly crenate, with short cilite, punc- 

 tures of the disc moderately coarse, regularly placed, not dense, near the lateral 

 margin very sparse. Elytra! punctures as coarse as those of the thorax and 

 rather deeper, as closely placed ; surface slightly scabrous, sutural costa well 

 marked, the discal costse scarcely visible. Pygidium convex, gibbous near apex 



9, punctures finer than on the thorax, scarcely visible near the apex. Metas- 

 ternum sparsely punctate, the hair very short and sparse. Abdomen sparsely 

 punctate, more coarsely in the female. Claws moderately arcuate, the tooth in- 

 tramedian in both sexes, and acute, longer in the female. Last joint of maxil- 

 lary palpi fusiform, not impressed. Length .72 — .97 inch ; 18 — 24.5 mm. 



Male. — Antennal club as long as the funiculus. Abdomen 

 broadly impressed at middle. Penultimate ventral segment with 

 vague oblique impressions, which meet at the suture in front, behind
