Figure 36 



Neohrotica semicostata Jacoby, in Godman and Salvin, Biologia Centrali-Ameri- 

 cana, Coleoptera, vol. 6, pt. 1, p. 574, 1887. 



About 6.5 mm. in length, elongate oblong oval, wider at the apical 

 end, dull, not shining, the elytra with many costae, the intervals being 

 coarsely geminate striate punctate, entirely pale. 



Head with interocular space half its width, a depression above the 

 frontal tubercles, occiput finely punctate and alutaceous, lower front 

 coarsely punctate on each side of the carina, a little pubescent, the 

 tips of the mandibles piceous. Antennae entirely yellow brown with 

 the three apical joints pale yellow. Prothorax almost rectangular 

 with slightly curved sides, a deep sulcus across the middle, surface 

 alutaceous, finely punctate, pale. ScuteUum pale. Elytra widened 

 below the middle, irregularly costate, the intervals with deep coarse 

 geminate punctures. Body beneath pale, legs pale, the claws a 

 little deeper in color. Length 6.7 mm.; width 3.5 mm. 



Type, female, BMNH, from Panistlahuaca, Mexico, collected by 

 Salle. 



Remarks: This is clearly closely related to Neohrotica pluristicta 

 Fall and N. sexmaculata Jacoby, but unlike them is without any dark 

 marks or spotting. Only a single specimen is known to me.

About 7 mm. in length, elongate oblong oval, shining although 

 faintly alutaceous, the elytra with niunerous fairly distinct costae, 

 with the intervals irregularly geminate striate punctate, pale yellow- 

 ish brown with a piceous head, deeper brown intermediate joints of 

 the antennae and brown tibiae and tarsi. 



Head with interocular space half the width of head, a median 

 depression over the frontal tubercles, a narrow carina running down 

 the lower front, shining, impunctate, piceous except for the pale neck 

 underneath. Antennae with paler basal and apical joints, intermedi- 

 ate ones deep brown. Prothorax much wider than long with rounded 

 sides and a transverse sulcus, shining although feebly alutaceous and 

 very finely and indistinctly punctate, entirely pale. Scutellum tan 

 colored. Elytra with 8 or 9 more or less distinct costae, the interspaces 

 irregularly geminate striate punctate, shining, although faintly
